Biomass high-temperature gasification boiler burner

Abstract

The invention discloses a biomass high-temperature gasification boiler burner. The biomass high-temperature gasification boiler burner comprises a furnace body; a furnace cavity is formed in the furnace body; multiple gasification combustion assisting air distribution pipes injected to surfaces of combustion materials are arranged on the side wall of the furnace cavity; a reciprocating fire grate, with a slag outlet end positioned in a boiler hearth, is arranged at the bottom of the furnace cavity; an injecting combustion channel, inserted in the boiler hearth, is arranged at the front end of the furnace cavity; and a smoke stop combustion assisting air supply device for forming an air curtain in the injecting combustion channel is arranged on the side wall of the injecting combustion channel. The biomass high-temperature gasification boiler burner uses the characteristic of hot air upwards moving for building a similarly closed biomass high-temperature gasification combustion environment in the furnace body; the highest combustion point temperature can reach 1200-1300 DEG C; all harmful gas, such as dioxin, is totally decomposed; and the biomass high-temperature gasification boiler burner greatly improves the heat energy use efficiency of materials, largely reduces the material combustion smoke discharge, improves the prior art in a breakthrough manner, and provides full guarantee for total resource utilization of the materials, in particular biomass.

Description

technical field [0001] The invention relates to the technical field of energy utilization, in particular to a biomass burner that injects heat energy after combustion to a boiler. Background technique [0002] Combustion furnaces in the prior art all supply air from the ash layer, no matter it is a common furnace or a counter-burning furnace, the air is first supplied to the incompletely burned ashes to continue burning, releasing residual heat energy; then it is provided to the combustion layer for combustion, releasing heat and Heat energy is provided to the reduction layer; the reduction layer absorbs heat energy, decomposes volatile matter, and burns the volatile matter to generate a large amount of heat energy required. [0003] Many technical problems will arise in the actual combustion of the above-mentioned combustion principle. Because the air is supplied from the ash layer, the highest temperature of combustion is in the combustion layer, and the temperature of th...

AI Technical Summary

Problems solved by technology

Because the air is supplied from the ash layer, the highest temperature of combustion is in the combustion layer, and the temperature of the combustion space above the reduction layer cannot meet the conditions for complete combustion of volatile matter, thus forming dense smoke, resulting in incomplete combustion, and making 70% of the heat of solid combustibles Value loss, a great waste of energy, pollution of the environment

Especially in the process of waste incineration, the dioxins produced by combustion cannot be decomposed without a high-temperature environment, so that the waste incineration technology cannot be promoted
