Abstract
Combustion of coal mine ventilation air methane (VAM) was investigated in a thermal reverse-flow reactor. Effects of CH 4 concentration, VAM flow and temperature were studied. The results show that combustion of coal mine ventilation air methane be achieved for methane concentration of 0.2%~0.8% in reactor. The conversion rates of CH 4 are all above 99%.Some heat could be recovered. With the increase of CH 4 concentration and VAM flow, the temperature of middle area increase, the volume of high temperature increase. It is to improve conversion rate of CH 4 . The lowest combustion temperature is 880degC.
