Biomass gasification furnace with efficient combustion

Abstract

The invention relates to a biomass gasification furnace with efficient combustion, comprising a furnace body, a heating combustion system, a feed system and a tail gas circulation system, wherein the furnace body is provided with an inner combustion chamber, the heating combustion system is arranged in the inner combustion chamber, the feed system is arranged at the top of the furnace body, and the tail gas circulation system is connected between the furnace body and the feed system; when the biomass gasification furnace works, biomass materials are firstly fed into the feed system, then enter the inner combustion chamber by the feed system, are heated by the heating combustion system in the inner combustion chamber for oxygen debt combustion, and then are gasified into biomass gas, and finally the biomass gas is discharged from the furnace body for storage or direct combustion utilization.

Description

technical field [0001] The present invention relates to a gasification furnace, in particular to a gasification furnace capable of gasifying biomass. Background technique [0002] As we all know, biomass refers to various organisms produced through photosynthesis using the atmosphere, water, land, etc., that is, all living organic substances that can grow are collectively referred to as biomass. It includes plants, animals and microorganisms. Broad concept: Biomass includes all plants, microorganisms, animals that feed on plants and microorganisms, and their wastes. Representative biomass is crops, crop waste, wood, wood waste and animal manure. Narrow concept: Biomass mainly refers to lignocellulose such as straw and trees other than grain and fruit in the process of agricultural and forestry production, leftovers of agricultural product processing industry, agricultural and forestry waste, and poultry manure and waste in the process of animal husbandry production, etc. ...

AI Technical Summary

Problems solved by technology

[0004] Biomass has many of the above-mentioned characteristics, but is limited by the backwardness of the current biomass treatment equipment technology. A large amount of biomass raw materials are often discarded or wasted through simple burning methods. For example, most of the current agricultural straw is simply burned. This way of disposal not only wastes resources but also causes great harm to the environment

At present, some biomass treatment equipments have many shortcomings such as low production efficiency, backward treatment methods, and low thermal efficiency conversion rate.
