A biomass particle semi-gasification combustion head

Abstract

The invention relates to a biomass particle semi-gasification combustion handpiece. The biomass particle semi-gasification combustion handpiece comprise a furnace body, a feeding device, a primary cyclone oxygenating system and a secondary cyclone oxygenating system. A gasification combustion chamber is arranged on the upper portion of the furnace body. A flame bridge is arranged on the lower portion of the furnace body. An interlayer water jacket is arranged on the side face of the gasification combustion chamber. A water-cooled flame spray pipe communicating with the outside is arranged on the upper side portion or the top of the gasification combustion chamber. Through the biomass particle semi-gasification combustion handpiece, biomass particles can be sufficiently combusted, the defects that the biomass particles are not combusted evenly, blue smoke and black smoke are generated, the ash content is high, and ash is too much are effectively overcome, the biomass particle combustion efficiency is improved by about 5%, waste heat is absorbed and utilized, energy is saved, and emission is reduced.

Description

technical field [0001] The invention relates to a biomass burning device, in particular to a biomass particle semi-gasification combustion head. It is generally used for civil heating, domestic energy or thermal power generation, and more is used to heat industrial boilers to replace traditional coal-fired. Background technique [0002] As a new type of renewable energy, biomass pellet fuel is widely used because of its high combustion heat, easy storage, easy transportation, and no pollution. However, when the biomass particle burner in the prior art burns, because of the pyrolysis gasification and volatilization of the biomass particles, the ratio is that the gasification volatiles account for about 60%, and the carbides account for about 40%; Insufficient or uneven oxygen supply; it is easy to cause insufficient combustion of volatiles or incomplete combustion to form blue smoke and black smoke; at the same time, the delivery volume of biomass pellet fuel is not easy to ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the object of the present invention is to provide a biomass particle semi-gasification combustion head, which can fully burn the biomass particles and effectively solve the problem of uneven combustion of the biomass particles and the generation of blue smoke and black smoke. The shortcomings of smoke, high ash content, and large ash content have improved the combustion efficiency of biomass pellets by about 5%, and the waste heat can be absorbed and utilized to save energy and reduce emissions.
