Abstract :
Combustion of coal mine ventilation air methane (VAM) was investigated in a thermal reverse-flow reactor. Effects of CH4 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 CH4 are all above 99%.Some heat could be recovered. With the increase of CH4 concentration and VAM flow, the temperature of middle area increase, the volume of high temperature increase. It is to improve conversion rate of CH4. The lowest combustion temperature is 880degC.
