Feeding mechanism and biomass burner applying same

Abstract

The invention relates to a feeding mechanism and a biomass burner applying the same. The feeding mechanism comprises a stock bin, wherein a discharge hole of the stock bin is communicated with a material conveying passage; a passage outlet formed in the bottom of the material conveying passage is communicated with a feeding passage; one end of the feeding passage is communicated with the interior of a combustion chamber, and the feeding passage is obliquely arranged; the exterior of the material conveying passage is provided with a sleeve; a sealed annular cavity is formed between the inner wall of the sleeve and the outer wall of the material conveying passage; the side wall of the material conveying passage positioned in the annular cavity is provided with a plurality of through holes which penetrate through the outer wall and the inner wall; <0}{0><}0{>an air inlet of the sleeve is communicated with an air pipe; the end part of the air pipe is provided with a blower; gas is introduced into the annular cavity through the air pipe by virtue of the blower, and enters into the material conveying passage through an inclined hole. The feeding mechanism has the advantages of being good in anti-clogging performance, high in material conveying efficiency, relatively full in biomass particle combustion, simplified in structure, reduced in production cost, and the like.

Description

Technical field: [0001] The invention belongs to the technical field of biomass energy utilization, and more specifically relates to a feeding mechanism and a biomass burner using the mechanism. Background technique: [0002] As we all know, the world is rich in biological resources in various forms, including crop straw, forestry waste, weeds and animal manure, etc. It is a huge renewable resource. If it is disposed of unreasonably (abandoned, incinerated), it will not only cause energy Waste, but also bring increasingly obvious environmental problems such as air pollution. A few days ago, the biomass burner provides the energy required for production by burning the heat generated by biomass. It is a relatively promising biomass energy utilization technology, which is gradually adopted by the industry. [0003] The existing biomass burners all have a biomass feed structure, which sends biomass particles into the combustion chamber, such as figure 1 As shown, the tradition...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of biomass feeding mechanism for the deficiencies of the prior art, which cancels the spiral propulsion structure of the traditional biomass feeding mechanism, and by adding an air path branch on the air induction channel, The biomass particles are quickly pushed into the combustion chamber by the airflow that enters the feeding channel from the inclined hole on the side wall of the feeding channel, increasing the fluidity of the biomass particles in the feeding channel, and avoiding the problem of biomass particle accumulation and blockage. Simplified structure and low production cost
