Ventilation Air Methane Abatement Safety Project
Experimental process and facilities
Below is a selection of the apparatus used in testing throughout the project. A range of gas, gas-dust and gas particulate explosions were ignited in varying concentrations and conditions. Data from this research has culminated in the design and construction of an at-scale VAM Capture Duct.
