Oxy-Fuel Technology

Conventional pf coal-fired boilers use air for combustion in which the nitrogen from the air dilutes the CO2 concentration in the flue gas. In oxy-fuel technology, combustion with oxygen typically of greater than 95% purity and recycled flue gas is used for combustion of the fuel. By recycling the flue gas, a gas consisting mainly of CO2 and water is generated, ready for sequestration without stripping of the CO2 from the gas stream. The recycled flue gas is used to control flame temperature and make up the volume of the missing N2 to ensure there is enough gas to carry the heat through the boiler.

Currently there are no full-scale plants using oxy-fuel combustion in operation. However, theoretical studies combined with laboratory and pilot-scale studies (typically 30 - 100 MWe) have been announced or are planned, which will lead to commercial deployment.

The Project

The Asia Partnership Partnership project supports an oxy-fuel working group (O-fWG) to coordinate collaboration through information sharing, and joint projects, between oxyfuel demonstrations and support development of the technology towards commercialisation.

Asia Pacific Partnership

The countries comprising the Asia Pacific Partnership are Australia, Canada, China, India, Japan, Korea, and the USA.
