Production method of continuous semi-fluidized fixed bed semi-water gas

The invention discloses a production method of continuous semi-fluidized fixed bed semi-water gas, and relates to a production method of semi-water gas. The method comprises the steps that A, active coal briquette is prepared; B, gas and liquid entering a furnace are prepared; oxygen-enriched air with an oxygen content of 56-65% and superheated steam are mixed uniformly according to a proportion that a volume ratio of O2 to H2O is 1:(1.5-2.0); the gas entering the furnace is obtained; C, gas-liquid reaction is conducted; the active coal briquette and the gas entering the furnace are input to a gasification reaction zone of a gas producer; temperature of the gasification reaction zone is controlled to be greater than an ash fusion point of the active coal briquette, so that the active coal briquette is fused to liquid coal and generates gas-liquid reaction with the gas entering the furnace; the semi-water gas and flow residue are generated; D, cooling is conducted; a gasifying agent is added continuously to th
