Experimental study on the premixed lean-burn in alumina particles based porous burner

Coal mine methane (CMM) emissions from underground coal mines is becoming a global problem since it produces greenhouse gas contributing to global warming. It is critical to reduce low-concentration CMM(LCM) and ventilation air methane (VAM) emissions, which has become the focus to be solved urgentl...
