BIOMASS GASIFIER PRODUCING LOW TAR

摘要

A low tar gas producing biomass gasifier is provided to use air introduced from the side as a gasification agent and to separate ashes in a grate at the bottom to produce synthesis gas. A low tar gas producing biomass gasifier includes: a biomass hopper(10) into which biomass materials are injected, an optical sensor(11) for measuring a reduction amount of the biomass, a combustion unit(60), an air injection unit with a plurality of nozzles(20) for injecting air from the lateral face of the combustion unit, a heat insulating layer(70) for maintaining gasification temperature of combustion gas, a grate(50) for receiving ashes produced by gasification, an ash collector(30), a reforming catalyst reaction layer(80) for removing tar, and a synthesis gas outlet(40).
