ABSTRACT:
The present invention relates to a method for producing coal gas, including: feeding raw material pulverized coal and a high temperature gasification agent (7) into a coal gas producer (a) for reaction to produce coal gas; performing heat exchange between the coal gas coming out of the coal gas producer and a gasification agent to produce the high temperature gasification agent (7); performing heat exchange between the coal gas, after performing heat exchange with the gasification agent, and water to produce vapor (4), wherein the vapor (4) is a component of the gasification agent; and outputting the coal gas after further dust removal and desulfuration which has performed heat exchange with the water.
