Yields of mine fuel under the heat effect of fire flame when methane explosions

摘要：

　　In order to study the mechanism of second-fire induced by methane explosions,the yields of several main fuels in mine were studied through doing some fast pyrolysis experiments.Use courier point fast pyrolysis system and GC to do this experiment.All experiment conditions fulfill methane explosions environment thoroughly.The experiment results show that the yields mainly include CH4,C2H4,C2H6,C3H6,C3Hs,C4,C5,CO,CO2 etc.Where,CH4,C2H4,C3H6,C4,C5,CO,CO2 yields are larger than others.Only supporting wood has H2,and only PVC has HCl but others.And include some dangerous flammable gas such as CH4,CO,H2 etc.The model and influence factors show that temperature and heating rate have great influence on yields but pressure,especially temperature.All results show that methane explosions could produce some flammable gas which out of fuel,and could induce second fire.
