Abstract

The invention provides a biomass gasification burner. The biomass gasification burner comprises a bracket, and a primary combustion tube is fixedly mounted at the top of the bracket. The nozzle at oneend of the primary combustion tube is a fuel inlet, and the other end of the primary combustion tube communicates with a secondary combustion tube. The secondary combustion tube comprises a secondarycombustion inner tube and a secondary combustion outer tube. A cracking disk arranged in the secondary combustion tube separates the secondary combustion inner tube into a gasification chamber and aflaming cavity, and the gasification chamber communicates with the flaming cavity through flame outlet holes in the cracking disk. The secondary combustion inner tube, the secondary combustion outer tube and the primary combustion tube enclose an annular cavity, and the cracking disk separates the annular cavity into a secondary oxygen supply chamber and a tertiary oxygen supply chamber. The secondary oxygen supply chamber communicates with the gasification chamber through vent holes, and the tertiary oxygen supply chamber communicates with the flaming cavity through the vent holes. A secondary oxygen supply tube and a tertiary oxygen supply tube separately communicate with the secondary oxygen supply chamber and the tertiary oxygen supply chamber. The biomass gasification burner can fullyburn biomass fuel, has high thermal efficiency and high gasification rate, and is beneficial to environmental protection.
