Possibility of combustible gas production from municipal solid waste(MSW)using hot blast face(BF)slag has been studied.The objective of this work is to generate combustible gas from MSW using heated BF slag.In this experiment,the thermal stability of the MSW was analyzed by theogravimetric analysis,and effects of temperature,gasifying agent(air,N2,steam)and BF slag on the gas products were investigated at 600-900 ℃.The thermogravimetric analysis indicates that the weight loss of MSW includes four stages:evaporation of the moisture,combustion of volatile materials,bing of carbon residue and bout of ash.The contents of the combustible gas increase with increasing temperature,and the lower calorific value(LCV)increases rapidly at 600-900 ℃.It is found that volume fraction of CO,H2 and CH4 at different atmospheres increases in the order N2＜air＜steam.It is believed that BF slag acts as the catalyst and the heat carrier,which promotes the gasification reactivity of MSW.
