Abstract
A pyrogenation gasification combustion device for biomass fuel is characterized in that a pyrogenation device is added inside a hearth of a boiler and is composed of a pyrogenation cylinder and a pyrogenation grate, and a material feeding device is arranged outside the hearth. The biomass fuel is pushed forward by a main spiral propeller and is gradually compressed when passing through a fuel passage to improve the degree of compaction and prevent pyrogenation gas from escaping; the biomass fuel is pushed to move on by subsequent fuel after entering the pyrogenation cylinder, and gradually falls on the pyrogenation grate to contact oxygen for ignition; the pyrogenation cylinder is heated by flame after ignition; the biomass fuel in the pyrogenation cylinder is heated to a temperature higher than that of pyrogenation; the biomass fuel carries out gas-solid separation; the gas can only escape from the flame on the pyrogenation grate; the combustible component therein is subjected to forced ignition; the flame goes up to the upper part of the hearth along the lateral face of the pyrogenation cylinder and is burnt out; at the same time the pyrogenation cylinder is heated for the continuous pyrogenation reaction therein; and the solid on the pyrogenation grate is broken to pieces, and falls or continuously burns on the pyrogenation grate.
