Continuously operated biomass forming fuel gasification combustor

Abstract

The invention discloses a continuously operated biomass forming fuel gasification combustor, belongs to the technical field of combustion of biomass forming fuels, and solves the problems in a traditional biomass forming fuel combustor. The continuously operated biomass forming fuel gasification combustor comprises a combustor body; the combustor body comprises a gasification combustion chamber; a feed port is formed in one side of the gasification combustion chamber; a fire grate and a primary wind port are arranged at the bottom of the gasification combustion chamber; a gas gathering area is arranged above the gasification combustion chamber; a gas nozzle is arranged on one side, farther from the feed port, of the gas gathering area; a secondary wind port is formed in the gas nozzle; the fire grate adopts a reciprocating fire grate; a tempering prevention wall is arranged in the upper side edge position of the feed port in the gasification combustion chamber; an isolation wall perpendicular to the fire grate is arranged in the gasification combustion chamber for dividing the gasification combustion chamber into two areas; an air hole is formed in the upper side of the isolation wall; and cyclone blades are arranged in the secondary wind port. The continuously operated biomass forming fuel gasification combustor is applied to gasification combustion of the biomass forming fuels.

Description

technical field [0001] The invention belongs to the technical field of biomass briquette fuel combustion, and in particular relates to a continuously operating biomass briquette fuel gasification burner. Background technique [0002] Biomass briquettes such as straw particles have many advantages such as high calorific value, environmental protection, and regeneration. The existing biomass briquette fuel burners are prone to slagging in the gasification chamber, and need to be shut down frequently for manual slagging, which cannot Continuous operation; Insufficient combustion; Direct-flow flame is generated, the diameter of the flame is small, the length is large, and it is directly sprayed onto the back wall to cause serious slagging of the back wall, resulting in a short maintenance cycle, and the molten slag on the back wall needs to be cleaned regularly, which is labor intensive and Problems such as low heat utilization rate need to be solved.

AI Technical Summary

Problems solved by technology

[0005] The beneficial effects of the present invention are as follows: the problem of intermittent operation of the existing burner due to slagging is solved; since the reciprocating grate is used, it can continuously feed materials, continuously discharge slagging, and prevent slagging; the temperature in the gasification chamber It can be controlled in a lower temperature range, and it is not easy to slagging while generating gas; the secondary air adopts a swirl structure to prevent the direct current flame from damaging the rear wall, the flame is full and high, and the heat utilization rate is high; the gasification combustion chamber is separated by a partition wall Divided into gasification area and fixed carbon burnout area to achieve staged combustion, the concentration of nitrogen oxides produced is low, and the environmental protection effect is good
