Principles of coal gasificationCoal gasification is the formation of water vapor and air mixture flowing through the high-temperature gasification agent produce a series of fixed-bed combustion of a chemical reaction process. The oxygen and steam in gasifying agent and fuel in the carbon reaction generated containing CO, CO2, H2, CH4, C2H4, N2 and many other components of the furnace gas. CO, H2, CH4, CmHn is combustible gases,
