Dynamic measurements of physical, chemical and thermal changes in the transformation of coal maceral concentrates were made during heating at a rate of 10°C/min to 1000°C. The endothermic and exothermic processes were identified by measurements of apparent specific heat while the fluidity was indicated by the estimated thermal conductivity. Measurements of swelling and bed permeability were made, with continuous quantitative elemental analysis of gases and tars as they evolved. Data for two coal concentrates of high and moderate vitrinite indicate that the same reactions and events are occurring for the two samples, but to a greater extent for the high vitrinite sample. The research has noted the significance of evolved tars in the early events, being the lowest temperature event identified, with rapid tar evolution prior to the onset of swelling associated with permeability change. Further tar release and gas evolution is associated with a rapid swelling event, this event being substantially greater for the high vitrinite sample. The data has also quantified contraction at higher temperatures following swelling which is associated with the release of hydrogen containing gases. Evolved tars from the high vitrinite sample showed elevated H/C ratio indicating that vitrinite tars appear to be more aliphatic than those evolved from inertinite. A comparison of measured swelling with estimated volumetric flow rate of the volatiles has indicated that thermo-expansion of coal utilised up to 21% of the volatiles to drive bubble growth. This utilisation rate varied significantly across the plastic temperature range.

Oxy-fuel combustion is a promising CCS technology which is being demonstrated prior to commercialisation. While the flue gas in oxy-fuel combustion is concentrated in CO2, it contains impurities such as SO2. The elimination of SO2 can provide a clean CO2 stream ready for storage. This paper is to understand the absorption of SO2 in scrubbing relevant to those used in oxy-fuel technology.Steady state experiments were conducted in a continuous well stirred reactor to understand the absorption rate of SO2/CO2 into a total concentration of 0.28M of mixtures of NaHSO3 and NaHCO3 simulating liquids formed by scrubbers using NaOH as the reagent at solution pH values from 4 to 7 with the exiting gas concentrations of SO2 from 19ppm to 1500ppm and a constant CO2 concentration of 70%. Online measurement included gas phase SO2 and liquid pH, and offline measurement included CO2 (aq), HCO3-, S (IV), SO32- and S (VI) after each experiment. Three aspects investigated were the impacts of pH on the solution chemistry, the significance of solution pH and the concentration of gas phase SO2 on the absorption rate of SO2.The total sulphur concentration in liquid was found to be related to the effectiveness of Na+. The effective ratio of Na+ can be defined as the total sulphur to Na+ ratio and this effectiveness ratio of Na+ is pH dependent. At pH<5, Na+ is 99% effective. It reduces dramatically from 99% at a pH 5 to less than 15% at pH above 7. With regard to carbon based species also absorbed, super saturation of CO2 (aq) was observed at pH>5.5. The concentration of HCO3- increases dramatically above pH 6 and below this pH, the concentration of HCO3- is negligible.The absorption rate of SO2 was found to increase with pH with some increase with the concentration of SO2. The operational pH window for scrubbing may be defined by an upper limit pH where the absorption rate of SO2 starts to decreases from the maximum absorption rate of SO2 and the lower limit pH where the absorption rate of SO2 reduces to half of the maximum absorption rate of SO2. Both the upper limit and the lower limit decrease initially and stay stable with the concentration of SO2. This decrease is caused by the reversible reaction of the hydrolysis of SO2 and confirmed by equilibrium experiments of SO2 and sodium solutions. Operation within region 2 (pH 5-6) is recommended, depending on the scrubber design. The operation exit pH of the produced liquid can be varied within the region.The absorption rates of SO2 obtained in the steady state experiments were predicted by a model based on the instantaneous reaction assumption. This model generally overestimates the absorption rates of SO2 at pH values below 6 indicating a kinetic limitation of SO2 and water reaction at low pH values. The analysis on the controlling regions indicates that the gas side mass transfer resistance decreases with the concentration of SO2. Liquid side resistance becomes more important at a lower pH and a higher concentration of SO2.

Oxy-fuel combustion is a promising CCS technology which is being demonstrated prior to commercialization. While the flue gas in oxy-fuel combustion is concentrated in CO2, it contains impurities such as SO2. The elimination of SO2 can provide a clean CO2 stream ready for storage. SO2 is commonly washed by sodium based spray towers with high efficiency but CO2 impacts are significant. A theoretical model was developed based on the two-film mass transfer model, and considering both the SO2 and CO2 reactions with sodium solutions. This model was firstly used to simulate the dynamic experimental results reported in our previous paper to confirm its applicability. With this model, simulations then were carried out on the absorption rate of SO2 into droplets with three droplet sizes: 100µm, 500µm and 1000µm, one sodium concentration of 0.08M (back calculated from liquid analysis), a range of pH from 4 to 12.5 and a range of SO2 concentrations from 19ppm to 1500ppm.Simulations focus on the impacts of droplet position, gas phase CO2 and droplet size on the absorption rate of SO2. These impacts are closely related with pH values. Taking a typical pH of 7 for example, the absorption rates of SO2 for droplets close to nozzles which move relative to the gas are significantly higher than these below nozzles which are at the terminal velocities, and the differences between two positions are larger for higher concentrations of SO2 with the concentrations range from 200ppm to 1500ppm. CO2 has a negative impact on the absorption rate of SO2 through reducing the gas phase mass transfer coefficient of SO2 in the gas phase controlled region and also through generating more acidic conditions at the liquid phase interface. Reducing the droplet size from 500µm to 100µm has a more significant improvement on the absorption rate of SO2 than from 1000µm to 500µm. Result: have implications in the controlling region and the operational liquid pH region. The controlling region is related to the droplet position. The droplets close to nozzles are located in the mixed controlled region or the gas film controlled region; and the droplets below nozzles can be located in three regions depending on the concentration of SO2 and pH. A lower concentration of SO2 and a higher pH are favourable for the absorption rates of SO2 to be located in the gas phase controlled region.The operational pH of the exit liquid may be established based on two criteria: a reasonable absorption rate of SO2 and a sodium reagent loss as NaHCO3. The optimal operational region is then in the region 2 where the absorption rate of SO2 is still high and reagent use is minimized. The region 2 can be further divided into four sub regions. In the region 2-1 and the region 2-2, the absorption rate is moderate, but there is too much Na+ wasted for CO2 capture. In the region 2-3, there is a moderate amount of Na+ wasted for CO2 capture. In the region 2-4, Na+ wasted for CO2 capture is minimized, but the effective ratio of Na+ is still not the maximum.The necessary operational pH region graph can be used to guide the operation of a spray tower.

Oxy-fuel combustion is a promising CCS technology which is being demonstrated prior to commercialization. While the flue gas in oxy-fuel combustion is concentrated in CO2, it contains impurities such as SO2. The reduction of SO2 prior to compression by a scrubber is a common feature of oxy-fuel systems. These scrubbers use sodium solutions. The products of the sodium-based scrubber after capture of SO2 contain Na2SO3 and NaHSO3. In the presence of O2 in the gas phase, sulphur related species (i.e., SO32- and HSO3-) in liquid phase will be irreversibly oxidized to sulphate. These sulphur related species are noted as S(IV). The oxidation of S(IV) could vary along the height of a spray tower due to changes in pH. The study of the S(IV) oxidation rate at different pH is helpful in evaluating the oxidation extent of S(IV) and understanding the impacts of S(IV) on the absorption rate of SO2.Both the heterogeneous oxidation and the homogeneous oxidation of S(IV) were studied here using two types of experimental reactors (Gas liquid reactor and liquid reactor). Heterogeneous experiments were conducted in the gas liquid reactor. In experiments, liquid phase pH and exit SO2 were recorded continuously. Liquids were also taken for sulphate analysis after certain time period (30-60min). For homogenous experiments, pH was monitored continuously and dissolved oxygen (DO) levels were manually recorded. For the heterogeneous oxidation, the oxidation of S(IV) results in reduction in pH, at pH 5.48, SO2 starts to be desorbed. With this reduction in pH, the oxidation rate of S(IV) changes accordingly. The oxidation of 0.01M S(IV) stays stable at pH>5.48. The oxidation rate of S(IV) drops by 44.5% at pH<5.48. For the homogeneous oxidation, there are three regions of oxidation rate. In region 1 (i.e., pH>5.6), the oxidation rate of S(IV) does not change with pH; in region 2 (i.e., 4.5332-.Comparisons between heterogeneous and homogeneous oxidation indicate that the heterogeneous oxidation rate of S(IV) at pH>5.48 is located in the liquid phase mass transfer controlled region. Below pH 5.48, the heterogeneous oxidation rate of S(IV) does not drop as much as homogeneous oxidation rate. This is possibly because the heterogeneous oxidation rate of S(IV) is enhanced by desorption of SO2 to produce SO32- for oxidation. Results have implications on the disposal of waste sodium solutions after absorption. The oxidation of S(IV) in discharged solutions results in a final pH of about 4 which may be neutralized to form Na2SO3 prior to disposal.

The interactions between vitrinite and inertinite-rich coals and the ionic liquid butylimidazolium chloride ([bmim][Cl]) heated to 100 C have been characterised. Differences in the interactions of coal macerals and ionic liquids have been identified. [bmim][Cl] is able to dissolve 22 wt% of a high-vitrinite coal fraction compared to 14 wt% of a high-inertinite coal fraction. The vitrinite-rich coal fraction tends to swell to a greater extent compared to the inertinite-rich coal fraction, which was fractured and fragmented rather than swelled. © 2013 Published by Elsevier Ltd.

The chemical looping air separation (CLAS) is a novel method for producing high-purity oxygen, which can be effectively integrated to oxy-fuel power plants. CuO/Cu2O, Mn2O3/Mn3O 4, and Co3O4/CoO have been found to be the most thermodynamically suitable oxidation pairs for the CLAS process. In the current study, the reactivity and stability of these metal oxides were analyzed further. A total of six different oxygen carrier samples were prepared by the dry impregnation method on SiO2 and Al2O3 supports. Their redox behavior has been investigated in a thermogravimetric analyzer (TGA) at four different temperatures, i.e., 800, 850, 900, and 950 C, where the temperature-programmed oxygen release and oxidation were applied for 5 continuous cycles using nitrogen and air, respectively. The results indicate that, although relatively all oxygen carriers exhibited good reactivity, CuO/Cu2O with SiO2 and Co3O4/CoO with Al2O3 were found to be most stable. Furthermore, oxygen transport capacity (OTC) (%) and rate of oxygen transport (ROT) (% min-1) were calculated. It was found that Cu oxide with SiO 2 has the highest OTC of 4.77% as well as the highest ROT of 5.1 and 10.9% min-1 for oxygen release and oxidation, respectively, at 950 C. The CuO/SiO2 oxygen carrier also exhibited better stability for the 41 continuous cycle test, with only 10.3% loss in OTC compared to 22.3% for Co3O4/Al2O3. The grain size growth was found to be the key cause in the loss of OTC. The oxygen concentration in the outlet stream for the CuO/SiO2 oxygen carrier was measured in packed-bed experiments at different temperatures. It was observed that the oxygen concentration at the outlet of the reactor was consistent with the equilibrium values at studied temperatures. © 2014 American Chemical Society.

The sulfur oxide (SOx) concentrations during oxy-fuel combustion are generally higher compared to conventional air firing. The higher SO x concentrations, particularly sulfur trioxide (SO3) in combination with high concentration of water in the recycled flue gas, increase the sulfuric acid dew point temperature in oxy-fuel fired systems, thereby increasing allowable flue gas temperatures and reducing the thermal efficiency of a power plant. This paper presents results of experiments carried out at a 20 kW once-through combustion rig of the Institute of Combustion and Power Plant Technology (IFK) of the University of Stuttgart simulating different extents of oxy-fuel recycle gas cleaning by impurities injection to the oxidant gas of a once-through combustion reactor. Three Australian coals that have previously been tested under air and oxy-fuel conditions at the Aioi furnace of IHI in Japan were used in the experiments. The SOx emissions were measured, conversion ratios of sulfur dioxide (SO2) to SO3 were calculated, and results were compared with existing literature, finding good agreement. The experiments with different extents of recycle gas cleaning and therefore different SO2 levels in the system, revealed differences in the SO3 generation behavior: A coal-specific trend of increasing conversion ratios of SO2 to SO3 with increased flue gas SO2 levels was observed that could be related to the ash composition of the three different coals. The capture of SOx in a baghouse filter was also evaluated. Acid dew point temperatures (ADPs) for the flue gas were calculated for the various firing conditions. Acid dew point (ADP) temperatures increased by up to 50°C when changing from air to oxy-firing with recycling of H2O and SO2. Considerable differences in the ADPs were found for different extents of oxy-fuel recycle gas treatment and were evaluated in respect to power plant efficiency implications. © 2014 American Chemical Society.

Ash produced during oxy-fuel combustion is expected to differ from ash produced during air combustion because of the higher CO2 and SO 2 atmospheres in which it is generated. For a quantitative understanding of the sulfation behavior of fly ash in oxy-fuel combustion, fly ash from three commercial Australian sub-bituminous coals was tested and decomposed under an inert atmosphere. Thermal evolved gas analysis was completed for ash produced in both air and oxy-fuel environments. Pure salts were also tested under the same conditions to allow for identification of the species in the ash that capture sulfur, along with thermodynamic modeling using FactSage 6.3. Sulfur evolved during the decomposition of air and oxy-fuel fly ash was compared to the total sulfur in the ash to close the sulfur balance. Both total sulfur captured by the ash and sulfur evolved during decomposition were higher for oxy-fuel fly ash than their air counterparts. Correlations of capture with ash chemistry are presented. © 2014 American Chemical Society.

The reaction of SO2 with fly ash in the presence of O2 and H2O involves a series of reactions that lead to the formation of SO3 and eventually H2SO4. Homogeneous experiments were conducted to evaluate the effects of the procedural variables, i.e., temperature, gas concentrations, and residence time, on the post-combustion conversion of SO2 to SO3. The results were compared to existing global kinetics and found to be dependent upon SO2, O2, residence time, and temperature and independent of H2O content. For a residence time of 1 s, temperatures of about 900 °C are needed to have an observable conversion of SO2 to SO3. Literature suggested that the conversion of SO2 to SO3 is dependent upon the iron oxide content of the fly ash. Experiments using three different fly ash samples from Australian sub-bituminous coals were used to investigate the catalytic effects of fly ash on SO2 conversion to SO3 at a temperature range of 400-1000 °C. It was observed that fly ash acts as a catalyst in the formation of SO3, with the largest conversion occurring at 700 °C. A homogeneous reaction at 700 °C, without fly ash present, converted 0.10% of the available SO2 to SO3. When fly ash was present, the conversion increased to 1.78%. The catalytic effect accounts for roughly 95% of the total conversion. Average SO3/SO2 conversion values between fly ash derived from air and oxy-fuel firing and under different flue gas environments were found to be similar.

Oxyfuel flue gas contains trace amounts of elemental mercury, which may corrode brazed aluminium heat exchangers used in the carbon dioxide purification system. International gas vendors have tested the use of the compression system to remove other flue gas impurities such as NOx; however, the reaction mechanism of mercury and its reaction products with NOx and nitric acid formed with condensed water vapour are unclear. This study used lab scale experiments to study the absorption of gaseous elemental mercury into nitric acid and the gas phase reaction between mercury and nitrogen dioxide formed from oxidised NO at pressures up to 25bar. It was observed that mercury has limited absorption into nitric acid and may partially desorb out of solution after depressurisation. On the other hand, mercury reacted readily with nitrogen dioxide (formed from nitric oxide oxidation at high pressure) in the gas phase. These gas phase reactions from the oxidation of nitric oxide to nitrogen dioxide to the subsequent oxidation of elemental mercury by nitrogen dioxide were predicted using existing global kinetic equations. The limited absorption of gaseous elemental mercury in nitric acid and significant oxidation of gaseous elemental mercury by nitrogen dioxide suggests that the primary removal step for elemental mercury is through the gas phase reaction. Oxyfuel compression circuits should therefore allow sufficient residence time for this gas phase reaction to occur. © 2014 Elsevier Ltd.

The desulfurization properties of Fe-Zn sorbent prepared by impregnating Fe and Zn into lignite char via ultrasonic-assisted impregnation (UAI) were investigated in comparison with the mechanical stirring (MS) method. The sulfidation experiments were carried out using a fixed-bed quartz reactor under ambient pressure. The amounts of metals loaded into char were measured by inductively coupled plasma atomic emission spectrometry (ICP-AES). The crystalline phases and chemical structure of sorbents before and after sulfidation were characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR), respectively. The morphology of sorbents was analyzed by using scanning electron microscope (SEM) with an energy dispersive X-ray (EDX) auxiliary. The experimental results showed that metal oxides as the active components were evenly dispersed on char as nanoparticles. The impregnation of active components was significantly improved by the ultrasonic-assisted impregnation method. When sorbents were prepared by ultrasonic-assisted impregnation, the metal oxide particles became smaller and more evenly dispersed on the char matrix which resulted in higher desulfurization efficiency and sulfur uptake capacity of the sorbents. The BET results showed that the physical properties of sorbents (surface area and pore volume) significantly improved when prepared by UAI method compared to MS method. The sulfidation temperature had a significant effect on desulfurization performance of char supported sorbents. The Fe:Zn molar ratio of 2:1, and impregnation time of 9. h were suggested as the optimal preparation conditions during ultrasonic-assisted impregnation.

A novel technique is described which provides quantitative and continuous analysis of light gas and condensable tar components as they are evolved in terms of carbon, hydrogen and oxygen. The technique has also been used to directly characterise the total tar sample in terms of carbon distribution and boiling point. It has been found that changes to the dynamic tar-H/C ratio correspond well with particular temperatures measured by Geiseler Plastometer for softening, maximum fluidity and re-solidification. This technique can enhance the chemical understanding of mechanisms occurring during de-polymerisation and cross-linking of coal (i.e. metaplast development and the transfer of hydrogen) while also monitoring tar evolution. A tar collection and re-vaporisation method provides a means of identifying tar groups that contribute towards the metaplast phase and temperatures at which they evolve. Both methods are unique in studying chemical aspects of coal and tar behaviour with heating, in a field based on thermo-physical techniques (e.g. H1 NMR, high temperature rheology, Geiseler plastometry, dilatation). Overall, the Dynamic Elemental Thermal Analysis (DETA) technique can give new insight into the fundamental mechanisms prevalent in coal pyrolysis and provides quantitative chemical assessment of tar nature (i) during the heating of coal and (ii) as a final (total) condensed product. © 2012 Elsevier Ltd.

Integrated Chemical Looping Air Separation (ICLAS) offers an energy efficient and cost effective option for large-scale oxygen generation in oxy-fuel type power plants. Oxygen production in the ICLAS is achieved by reduction of oxidised metal oxides in an environment of steam/recycled flue gas (CO2-rich) using a dedicated reduction reactor. This paper provides the results of a thermodynamic investigation into the effect of flue gas impurities on the reduction of three metal oxide oxygen carriers (Cu, Mn and Co oxides) under conditions pertinent to an oxy-fuel coal-fired power plant. Relevant calculations were carried out using the Fact-sage 6.1 thermodynamic equilibrium calculation software package. Different gas streams, namely crude/wet, dry, pure CO2 and steam were considered in the simulations together with the additional hypothetical impure flue gas stream having larger concentrations of CO, SO2 and NO. Effects of SO2, NO, CO and O2 contents of the flue gas on oxygen carrier conversion and oxygen decoupling process were investigated in detail. It was established that the successful reduction of metal oxides in the presence of flue gas impurities can only be achieved at higher temperatures due to increased partial pressure of O2 and the formation of metal sulphates at temperatures less than 800-900 °C. This may increase the operating and capital costs of the CLAS based oxygen production. © 2012 Elsevier Ltd. All rights reserved.

A fundamental study on the behaviour of heating coal macerals has been undertaken using two novel thermal analysis techniques. The apparent specific heat was determined during heating using an inverse calorimetric method (computer aided thermal analysis, CATA) and combined with pressure and displacement measurements to correlate endothermic and exothermic behaviour with measurement of swelling. The second technique used a post-oxidation stage to combust the tars and gases into products which were analysed. This method was used to study the elemental character of volatiles release from coal maceral concentrates in terms of carbon and hydrogen. Extents of swelling and exothermicity during primary devolatilisation were found to be correlated with vitrinite content and were associated with tar evolution. For the highest vitrinite fraction (of 86.4% vitrinite) swelling was initiated at the same temperature range for exothermic reactions, and maximum swelling coincided with the peak release of light gases. Tar evolution was found to change in chemical character (as defined by H/C ratio) during progressive heating, initially rising in the early stages of tar formation (<430°C) to a maximum of 1.24, then gradually decreasing to a minimum of 0.64 at 550°C. © 2012 The Combustion Institute.

Oxyfuel combustion enables carbon dioxide capture for storage and can therefore significantly reduce carbon dioxide emissions from coal fired power plants. However, CO2 derived from oxyfuel combustion has impurities that cause corrosion to plant equipment and transport lines and may be subjected to certain storage and end user requirements. The use of the CO2 compression system in an oxyfuel power plant to remove these impurities has been proposed and tested by international gas vendors both at laboratory and power-plant scale; however the extent of quantitative removal of these impurities by the compression system is unknown. The current research uses laboratory experiments to study the reactions of nitrogen oxides in the compression system. These include the oxidation of NO to NO2 in the gas phase, the absorption in liquid water and also reactions with water vapour in conditions from ambient conditions to pressures of 30bar. The reactor used was a bubble column that was preloaded with liquid water. Results show that nitric oxide is readily oxidised to water-soluble nitrogen dioxide at elevated pressures. This reaction is kinetically controlled and can be predicted using an equation derived for atmospheric pressure conditions. The resulting nitrogen dioxide is shown to react with liquid water to form nitrous and nitric acid. Single experiments also showed the potential for gas phase acid formation and condensation. Overall mass balances across the gas-liquid system were complicated by the stability of the absorbed NOx species in the liquid. © 2013 Elsevier Ltd.

Oxy-fuel combustion is an emerging technology to mitigate CO2 emissions from power plants. Compared with other CO2 capture technologies, gas impurities in oxy-fuel flue gas are highly concentrated, among which SO2 is of concern. Sodium based quench units have been used in oxyfuel projects to directly cool the gas prior to compression and to also remove SO2. However, the high concentration of CO2 in the flue gas can interfere with the capture of SO2. Dynamic transient experiments were therefore conducted in a semi-batch well stirred reactor (WSR) to study the mechanisms of SO2 absorption from gas mixtures of both SO2/N2 and SO2/CO2 into sodium based aqueous solutions, with measurements of SO2 absorption rate and decreasing liquid pH during the experiments. The liquids were analysed by ion chromatography (IC) and acid titration with equilibrium calculations to estimate sulfur and carbon species formed in the liquid.The dynamic absorption results for SO2/CO2 show three pH regions of absorption behaviour as pH reduced during the experiments, namely, region 1 with a constant gas absorption rate at pH values above 8.32 (this being 9.65 for the SO2/N2 experiments); region 2 where the gas absorption rate reduced at pH values from 8.32 to 4.22 (from 9.65 to 4.82 for SO2/N2); and region 3 where gas absorption reduced rapidly with pH, at pH values below 4.22 (4.82 for SO2/N2). From liquid analyses and thermodynamic calculations it is concluded that region 1 is associated with the consumption of OH- to give SO32-, region 2 with the consumption of HCO3-/SO32- and the formation of HSO3-, and region 3 with the consumption of H2O and the accumulation of HSO3- and SO2.The operational pH of the sodium based quench units is recommended to be in region 2, where a high absorption rate of SO2 and low sodium loss are expected. An operational pH window is thereby defined in terms of upper and lower limits. The operational pH window is found to be related to the concentration of sodium solutions when an inlet concentration of SO2 is proximately 3000ppm, and the window narrows at high concentrations of sodium solutions. The operational window is secondarily related with the concentrations of SO2 and narrows at low concentrations of SO2. © 2013 Elsevier Ltd.

In coal combustion, NOx is largely formed from the oxidation of volatile nitrogen compounds such as HCN and NH3. The experiments on the volatile-N conversion to NO at O2/CO2 atmosphere were carried out in a drop tube furnace. The effects of the excess oxygen ratio ¿ (0.6-1.4), temperature (1000-1300 °C), O2/CO2 ratio, and as well as CH4/NH3mole ratio were investigated. To further understand the importance of NO reburn during volatile combustion, experiments were also performed with different concentrations of background NO (0-950 ppm). The results show that volatile-N conversion to NO is sensitive to excess oxygen ratio ¿ at strongly oxidizing atmosphere. For volatile combustion, there is an optimal temperature and inlet O2 concentration to minimize the volatile-N conversion to NO. The CH 4/NH3 mole ratio plays an important role on the NO formation under oxidizing atmosphere. High levels of background NO prohibit the volatile-N conversion to NO significantly as the volatile-N conversion ratio decreases by 19-36%. The reburn fractions of recycle NO in fuel-rich and fuel-lean condition are 14.8% and 9.8% at 1200 °C, respectively. © Tsinghua University Press, Beijing and Springer-Verlag Berlin Heidelberg 2012.

Chars were made from four Australian coals of varying vitrinite content at pressures of 5, 10, and 15 atm. The morphology of the chars was correlated with the petrography of the parent coal. The intrinsic reaction rates of the chars at high pressures were measured, and no systematic effect of pyrolysis pressure or maceral concentration was found. It is concluded that observed variations in conversion rates under process conditions are likely to be due to char structural properties and not a result of variation in the intrinsic reactivity of the carbon in the chars. Consequently, this paper presents a char structural submodel that is integrated into an existing char combustion model to account for the combustion behavior of char particles of different morphologies. The char morphology used in the model was predicted using the developed correlation with parent coal petrography, so that a petrographic analysis as well as the proximate and ultimate analyses is required for model input. Validation of the model shows that chars produced at high pressure with a high percentage of cenospherical types burn more rapidly under process conditions than those at low pressure, with model predictions matching measurements. It is suggested that incorporating the char structural submodel into the existing char combustion model improves its predictability.

A mechanistic study is detailed in which coal ash is heated with its shrinkage measured continuously up to a temperature of 1600°C. The temperatures corresponding to the rapid rate of shrinkage are shown to correspond to the formation of eutectics identified on phase diagrams. Samples were therefore heated to these temperatures, cooled rapidly and examined with an SEM to identify the associated chemical and physical changes. The progressive changes in the range of chemical analysis (from SEM), the extent of undissolved ash particles and porosity were then quantified and related to homogenisation, viscosity and ash fusion mechanisms.

The ignition characteristics of a cloud of pulverised coal flowing in a drop-tube furnace are examined.Cloud ignition is defined at the minimum gas temperature at which significant oxygen consumption occurs. This is accompanied by the generation of carbon dioxide and oxides of nitrogen, and the formation of a visual flame. Cloud ignition occurs at several hundred degrees above that for the ignition of some single coal particles. For three coals the cloud ignition temperature decreased with oxygen partial pressure, but was not sensitive to fuel equivalence ratio or particle size (as has been observed for single particles). For the three coals examined, pyrolysis measurements show the existence of a tar/light hydrocarbon/oxygenmixture at the cloud ignition temperature. On combustion the accompanying temperature increase results in coal burnoffs from 35 to 65% even though the combustible volatile matter prior to the ignition event corresponds to less than 6.5% burnoff. Different trends of tar and methane combustion and soot formation are observed in the experiments as gas temperature and oxygen levels were changed; however, significant tar combustion was always observed at cloud ignition. A mechanistic model is proposed to explain the observations. © 1994 Combustion Institute.

The character of fireside ash deposites depend on the propocesses by which deposits are formed and subsequent reactions within the deposit and with furnancegases. The properties influencing furnance heat transfer. absorptivity for radiative transfer and thermal conductivity for conductive transfer are shown from many measurements to dependent on this character. Illustrative trends in these properties as deposits mature and grow are presented together with their effect on furnance exit temperature and efficiency. The reflective character of initial deposits from particular coals is then considered with predictions and measurements of the spectral character of such deposits, during the first three hours of growth, using on-line FTIR spectroscopy.

Experimental studies are detailed which examine the control of sodium based fouling and slagging of a Victorian brown coal. The ash forming elements namely-Na, Mg, Ca, Fe, Al, Cl, and S in the particular coal-are bound within the coal matrix to oxygenated functional groups. The coal also contains discrete 8 to 80 micrometers mineral particles of silica. The coal was firstly treated to adjust levels of Na, Cl and Al by (a) washing with water to reduce the levels of Na and Ci, (b) washing with an aqueous solution of aluminium lactate to reduce the levels of Na and Cl and to increase the levels of soluble aluminium, (c) adding aluminium lactate to the coal without reducing Na and Ci (d) adding sodium aceta to the coal without reducing Na and Cl and (e) adding sodium acetate and aluminium lactate without reducing Na and Cl. Closely controlled combustion experiments utilising a drop-tube furnace temperatures of 1000 °C,1200 °C and 1400 °C have been conducted.

During combustion the inorganic constituents of coal are transformed into products (including vapors, aerosols and residual ash particles) which may transfer to furnace walls and form deposits which restrict heat transfer. Many of the mechanisms of these transformations have now been identified and are detailed by considering the elements, iron and sodium, which have been associated with slagging and fouling respectively. Developments in the scientific analysis of ash deposition, based on these mechanisms, include techniques for coal characterisation, control techniques, the development of engineering deposition parameters and mathematical modelling of the processes. © 1992 Combustion Institute.

Contrary to widely held belief optical fibre cables in hazards are not intrinsically safe. This paper presents the results of both experimental and theoretical investigations into the intrinsic safety of optical fibre in combustible environments. Continuous wave (CW) optical power in the order of 100 mW and pulsed optical power in the order of 10 W (peak) with 100 µs pulse width and 10 Hz repetition rate (average power of 10 mW), delivered by multimode optical fibres, and incident onto dust particles, created explosions in H2/air and CH4/air mixtures. These power levels are generally higher than those used in communication systems but are not atypical of certain sensing systems. A mathematical model was developed to predict the optical power required to ignite a combustible gas by optically heating a small particle and to verify the ignition/explosion mechanisms. The effects of gas concentrations, particle size and particle surface reaction are determined and particle-laser beam interaction are detailed. The model suggests that reactive coal particles can change the gas ignition/explosion behaviour as the coal/oxygen combustion generates thermal energy to increase the particle heating, or consumes oxygen locally to cease the ignition of gases. © 1992 Combustion Institute.

Maceral concentrates, extracted by selective sampling from the coal face, were burnt as pulverised fuel in order to obtain the temperatures of many hundred individual particles of pulverised coal at several combustion times by two-colour pyrometry. The concentrate having a 93.7% vitrinite-rich analysis generates chars of fine walled cenospheres, with openings in the walls, which burn at high temperature, whereas the concentrate with a 89.2% intertinite-rich analysis generates chars of lower porosity and higher density which burn at a lower, and more uniform, temperature. The vitrinite-rich concentrate also burns with an increasing spread in the population of particle temperatures, the inertinite-rich concentrate burns with a decrease in this spread. Due to higher char densities and lower reactivities the burning time of the inertinite-rich concentrate is estimated to be from 2.9 to 3.8 times that of the vitrinite-rich concentrate. Reactivity distributions are estimated from the temperature populations by fixing the activation energy of the chemical rate coefficient and allowing the pre-exponential factor to accommodate the reactivity spread. An increase in the spread of the estimated distributions is evident at high burnoffs. © 1992 Combustion Institute.

The kinetics of combustion of a size-graded fractions of petroleum coke (VM 0.9% db) of pulverised fuel size is determined by measuring the carbon burning rate in a CSIRO laminar flow reactor and using a critical ignition technique where a pulse of coke falls into a drop-tube furnace. At the temperatures where a visible flash is observed in the ignition technique little combustion is found to occur and the coke reactivities estimated assuming heterogeneous ignition exceed those from the burning rate by factors from 102 to 103 depending on assumptions made regarding the products of combustion and the definition of the critical ignition temperature. Ignition experiments with coke recycled through the furnace and coke doped with volatile materials indicate the temperature where flashing is detected decreases as volatiles are added and increases as volatiles are removed. The common assumption of heterogeneous ignition in such experiments may not be valid even for fuels of such low volatility. © 1991 Combustion Institute.

Reactions of sodium with mineral silicates contribute to the formation of fireside deposits during the combustion of some high sodium coals. A systematic experimental study of the reactions between sodium with inherent silica and kaolin during pulverised coal combustion was undertaken in order to examine the mechanisms of the reactions. The experiments were conducted in a drop tube furnace with coal samples which had been specially prepared to control the concentrations, the size and the distribution of the inorganic constituents, which included silica, kaolin, sodium chloride, sodium acetate, and gaseous SO2 to simulate organic sulfur. The rate of formation of sodium silicate was found to increase with temperature but the extent of formation was limited by the progressive agglomeration and coalescence of the ash which reduced the surface area available for reaction. The extent of interaction between the sodium and silica/silicates was reduced by the presence of chlorine and sulphur and this effect was greater with kaolin than with quartz. At gas temperatures of 1200-1400°C, sodium was volatilised from the coal before significant reactions occurred with the silica. At 1000°C the sodium was not fully released prior to the commencement of the silicate formation reaction. © 1991 Combustion Institute.

A theoretical-experimental study of the combustion of pulverized coal in the blowpipe and raceway of the blast furnace was undertaken. The objective of the study was to develop a mathematical model of combustion, and to evaluate it against experimental data. Both experimental and theoretical work involved three levels of complexity: (1) Laboratory-scale studies on coal devolatilization; (2) Pilot-scale combustion studies in a physical blowpipe-model; and (3) Combustion studies in a full-scale blast furnace. The predictions of the theoretical models compared favourably with the experimental data. Coal grind and devolatilization characteristics are shown to have a substantial effect on coal burnoff. Dispersion of the injected coal within the main blast is found to have a significant effect on coal burnoff. Gas recirculation and coke combustion within the raceway are found to influence the combustion of the injected coal. © 1988 Combustion Institute.

Furnace heat transfer models-using the zone and flux methods-have previously beenevaluated against measurements from the M1-furnace trials of the International Flame Research Foundation. The M1 furnace configuration is shown to be insensitive to flame and combustion changes and is, therefore, a poor test of a model. A simple zoned model-using the Monte Carlo technique-is then evaluated on the later, more sensitive, M2-trials when the proportion of the furnace walls as a heat sink was increased. The model allows for variation in flame shape and the concentration of emitters between zones. A simple zoning for the end-fired furnace comprising a single flame zone, a recirculation region and two zones between the flame and the furnace exist is shown to be quite adequate for predictions of furnace heat transfer. A more detailed description of the flame and furnace may not be warranted even when the flow and combustion pattern is known in detail. © 1982 Combustion Institute.

Measurements are presented of the flow pattern and mixing within the quarl of a 1/9th-scaleair model of a brown coal burner. For flow conditions within the range used in operating burners, two flow types were observed: one, previously reported, where the primary (coal-laden) flow is deflected gradually around a central, swirl-induced, reverse-flow zone; the other, where the primary flow partially penetrates the reverse-flow zone before being deflected rapidly in the radial direction. The combustion behaviour of the coal in each type of flow is predicted by a computationalmodel, and the results compared with limited measurements on an industrial burner. The second type of flow is shown to mix the coal-laden primary flow with the internal reverse flow before mixing with the secondary air flow, resulting in a higher evolution of volatiles and the ignition of a greater proportion of the char mass. The temperature field within the quarl is shown to be dominated by the temperature of the reverse flow. © 1982 Combustion Institute.

Narrow wave-band measurements have been used to determine the absorption coefficient of combustion chamber gases in large utility boilers with an accuracy of about ±25%. Effective absorption efficiencies and refractive indices for the fly ash have been deduced where dust burden details could be measured. Modifications to instrument design would improve the accuracy. The absorption characteristics were shown to be influenced by the chemical composition of the ash. For a brown and a sub-bituminous coal of high alkali ash the measurements indicated a very high specific surface in the furnace, incompatible with sizing of collected fly ash samples, and a very high wavelength dependence of absorption. Small molten particles in the furnace gases could account for the high apparent surface area and the wavelength dependence. Results for two bituminous coals with high ash fusion temperatures indicate that an absorption coefficient Ka of 0.4 to 0.5 would be adequate for engineering purposes. However this value appears to be strongly influenced by chemical composition of ash; the cloud surface area may be more dependent on inherent ash and combustion characteristics than on the total ash or the coal grind.

Performance is reported for quasi-steady state computational models of two zones of borehole type in-situ gasification systems. The plug-flow reduction zone is a close replica of real systems; the well-stirred reactor models some special systems and may be indicative of a wide range of ignition zone conditions. For both models it is postulated that seam moisture evaporation and coal devolatilization occur at some distance (inversely proportional to the advance rate) behind a reacting face of coke and that reaction of these products with coke occurs behind the face. This model produces an apparent reactivity for the system more strongly dependent on seam moisture and volatile content than on the chemical reactivity of the coke. Computations predict that gasification efficiency and combustion stability are sensitive to an optimal combination of seam moisture and of blast moisture. These findings and the predicted gas analyses and efficiencies are generally in line with what published field information is available. The advantageous effect of high moisture content in the gas is to increase reaction rate (by increasing the concentration of a major reactant); this is balanced by the temperature drop due to added heat capacity. The overall effect is so dramatic as to warrant this type of analysis before completing design for field experiments. Laboratory testing on large samples of seam coal is advisable to test the model for detail and obtain better rate coefficients. It is predicted that high ratings and high gasification efficiencies are possible for oxygensteam gasification either in plug-flow or W.S.R. systems, particularly if preheat can be achieved. © 1977 Combustion Institute.

A mechanistic model of a tangentially-fired pulverised-fuel furnace of 900 MW thermal input is described, in which a zoned method of computation predicts the temperature distribution within the chamber and the heat absorbed by the water-tube walls. The cylindrical model, comprising 45 gas and 21 surface zones, approximates the furnace, which is rectangular in cross section. The flow pattern within the chamber is assumed but the treatment of coal combustion and the complexities of radiative inter-change are rigorous within the liminations of the method. A series of simulations to demonstrate the effect of variation in gas flow pattern, boiler load and ash content in the coal is presented. These show that variation in the specific surface of the ash has a dominating influence, whereas the effect of the flow pattern is smally by comparison. Measurements taken on the actual furnace provide a check on the validity of the model. Comparisons are generally good although temperature predicted close to the furnace walls at burner level are consistently low. Investigations to improve the comparisons, and the method in general, are recommended. © 1975 Combustion Institute.

To increase our knowledge of the role played by particulate matter in radiative transfer inindustrial furnaces, solids-absorption coefficients in the burner region of a tangentially corner-fired pulverized brown-coal boiler are estimated and predicted by various methods. The total solids spectral absorption coefficient is given by ktsol=klsol+A.Csoot/¿, where klsol is due to large-solids (coal, char, ash) and the soot contribution depends on its concentration and the constant A. Radiation pyrometer data, at 0.65 and 0.90 µm, together with suction-temperature data, allows solution for the constants in this equation. A monochromatic intensity calculation along a pyrometer beam to estimate spectral-absorption coefficients is developed and the results of this calculation are used to obtain klsol and Csoot. These values indicate that soot contributes equally with large solids to the total solids emission, and dominates the visible emission. It is shown that large-solids-absorption coefficients can be estimated by a burn-out calculation,and that these values are in reasonable agreement with those obtained independently by radiation measurements. Values obtained for soot-absorption coefficients by radiation measurements are only about one-third as high as those estimated by an empirical equation quoted by Ledinegg. The availability of absorption-coefficient data and estimation methods such as these can contribute significantly to progress in the prediction of radiation from p.f. flames in industrial chambers by the well-known zone technique. © 1973 Combustion Institute.

This paper presents results on experiments carried out at a 20 kW combustion rig simulating different extents of oxy-fuel recycle gas cleaning by impurities injection to the oxidant gas of the once-through combustion reactor. A comprehensive set of total (Hgtot), elemental (Hg0) and oxidized (Hg2+) mercury as well as SO3 concentrations was obtained before and after the combustion rig's baghouse filter for in total 14 air and oxy-fuel experiments with 3 Australian coals. Based on this data, an assessment in respect to Hg oxidation, SO2/SO3 conversion and Hg and SO3 capture on the test rig's filter was performed. The air and the oxyfuel experiments with different extents of recycle gas cleaning, revealed differences in the Hg and SO3 formation and capture behavior: The Hg2+/Hgtot ratios in the flue gas are higher during oxy-fuel combustion compared to air-firing. This effect is even more pronounced at the filter outlet, after flue gas has passed through the filter ash. In some experiments, even a net oxidation of Hg0 entering the filter to Hg2+ was observed. The Hg capture by ash in the baghouse filter has been found to reduce the Hg emissions considerably. However, the Hg capture was altered by the different oxy-fuel recycle configurations, leading to decreased Hg capture efficiencies on the filter for one of the coals. A coal-specific trend of increased SO2/SO3 conversion ratios with increased flue gas SO2 levels was observed that could be related to the ash composition of the three different coals. This and the higher SO2 concentrations in the flue gas lead to considerably higher SO3 levels in oxy-fuel combustion with SO2 recycling. During the experiments, also a considerable capture of SO3 in the baghouse filter was observed (up to 80% under air- And up to 66% under oxy-fired conditions). A reduction of the SO3 capture on the filter under oxy-fuel conditions may be related to the higher SO3 levels in this process.
