Abstract

See full text

A method for gasifying biomass. The method includes: a) grinding the biomass, feeding the biomass into a gasifier while spraying superheated water vapor into the gasifier, controlling the gasifier at an operating temperature of 1200-1600° C., contacting the biomass with the superheated water vapor, desiccating, separating volatile matters, pyrolyzing, and gasifying the biomass to produce crude synthetic gas and ash; b) transporting the crude synthetic gas into a spray tower, quenching the crude synthetic gas by spraying water to cool down the crude synthetic gas to a temperature of 650-800° C., condensing a slag and a tar from the crude synthetic gas, dissolving and removing alkali metal oxides and part of acid gas to obtain primary synthetic gas; and c) cooling, dust removing, deacidifying, and desiccating the primary synthetic gas to transform the primary synthetic gas into clean synthetic gas.
