Utilization of ventilation air methane (VAM) from coal mine shafts is presented. In Poland nearly 600 millions m3/year of CH4 is emitted to the atmosphere. Despite that concentration of VAM varies within the range of 0.1-0.6 vol.% utilization of this methane is very important for future energy conservation. The most promising solution seems to be autothermal combustion in thermal flow reversal reactor (TFRR). A short review of the principle of flow reversal reactor (FRR) and experimental results of non-catalytic combustion of lean methane-air mixtures in a TFRR research & demonstration plant (gas flowrates up to 420 m3/h) as well as its mathematical model are presented. The modelwas validated by comparing experimental data with simulated results and the agreement obtained was satisfactory.
