Beschreibung
Zusammenfassung:	The invention relates to coal gas electricity generation, and provides a low heating value coal gas electricity generation method. The method comprises the steps that low heating value coal gas is introduced into a combustion chamber for combustion, and meanwhile water liquid inside a drum is introduced into the water cooling wall of a furnace body; heat generated by the low heating value coal gas combustion heats the water liquid inside the water cooling wall, the water liquid is subjected to phase change to become a steam-water mixture, the steam-water mixture enters the drum to be separated, saturated steam separated out is heated again through a heat unit to generate superheated steam, the superheated steam is introduced into a high pressure cylinder of a steam turbine for impulse starting electricity generation, steam for reducing temperature and pressure can be heated again through a high-temperature reheater and a low-temperature reheater to be superheated steam, the superheated steam is introduced int
