Abstract:

Abstract: experimental through deploying extremely low concentrations methane whose concentration are 0.75% to imitate coal mine ventilation air methane. Making the 0.75% concentration of methane through high temperature furnace, and collect the exclude gases of furnace. Then to detect the collected gas and confirm the conditions and characteristics of coal mine ventilation air methane.The study show; when The same concentration of VAM different flow rates through the high temperature furnace,Its flow rate is greater the higher the furnace temperature needed for complete oxidation;Flow rate the smaller the lower the temperature of oxidation required;

Key words: Key words: VAM, the extremely low concentrations, High-temperature oxidation, High-temperature furnace
