[0003] The combustion method of the biomass reciprocating grate in the prior art is mostly the direct combustion type, that is, there is only one air in the combustion, the combustion is insufficient, the thermal efficiency is low, and the smoke emission is large, causing environmental pollution and great waste of energy
In the biomass burning device with a fixed grate, the fuel is dropped on the grate from the feed system and accumulated. Due to the uneven combustion of the fuel on the grate, the local temperature is too high, and coking often occurs, which makes the boiler The thermal efficiency is greatly reduced

Abstract
The invention discloses an automatic decoking biomass semi-gasification combustion device, which comprises a feeding port, a feeding motor, a feeding motor support, a chain wheel, a chain, a feeding pipe, an igniter pipe, an air blower interface, a connecting rod limiting pipe, a crank connecting rod mechanism, a cylindrical pin, an eccentric wheel, a reciprocating motor support, a reciprocating motor, a combustion chamber, a gasification wall, a secondary air hole, a reciprocating grate, a primary air hole, a feeding spiral conveyer, a connecting rod and a rail groove. The device is reasonable in structural design; air enters a cavity formed by the gasification wall and the combustion chamber from an air inlet and then goes out from air holes in the gasification wall and the reciprocatinggrate, so that secondary oxygen gasification combustion can be assisted to make biomass combustion more sufficient, and residues are reduced; the device is compact in structural design; and the reciprocating grate reciprocates at the bottom of the combustion chamber, and fuel can be conveyed to the middle of the combustion chamber, slag pushing and decoking are conducted regularly, so that oxygensupply of the combustion chamber is smooth, normal gasification combustion of the fuel is guaranteed, the combustion efficiency is improved, and practicability is high.
Description
technical field [0001] The invention relates to a combustion structure, in particular to an automatic decoking biomass semi-gasification combustion device, which belongs to the technical field of combustion devices. Background technique [0002] The burner is a general term for devices that make fuel and air spray out and combust in a certain way. Burners are divided into industrial burners, burners, civil burners, and special burners according to types and application fields. It is mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or metal titanium. The function of the burner is to atomize the sample by flame combustion. The atomized test solution enters the burner, and under the action of flame temperature and flame atmosphere, it undergoes drying, melting, evaporation, dissociation and other processes to produce a large number of ground state atoms, as well as some excited state atoms, ions and molecules. [0003] The c...
