气化采煤技术是指将处于地下的煤炭在特定的设备内进行有控制的燃烧,在一定温度和压力的作用下使煤中含能成分与氧、水蒸气等气化剂发生一系列的化学反应,将固体煤直接转化为含有氢气、一氧化碳、甲烷等可燃性气体,最终输出地面的过程,被誉为第二代采煤法。分析了气化采煤技术优势,介绍了目前广泛应用的三种主要的气化采煤技术工艺,即固定床气化工艺、流化床气化工艺和气流床气化工艺,以期为煤炭生产提供参考。 Gasification coal mining technology refers to underground coal in a specific equipment for controlled combustion, under the action of a certain temperature and pressure make coal containing energy composition and oxygen, water vapor and other gasification agent a series of Chemical reactions, the direct conversion of solid coal containing hydrogen, carbon monoxide, methane and other flammable gases, the final output of the ground process, known as the second generation mining method. This paper analyzes the advantages of gasification coal mining technology and introduces three main technologies of gasification coal mining which are widely used at present, namely fixed bed gasification process, fluidized bed gasification process and entrained flow gasification process, for reference.
