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

Abstract

The invention relates to a feeding mechanism and a biomass burner using the mechanism, including a silo, the outlet of the silo is connected to a feeding channel, and the channel outlet and one end opened at the bottom of the feeding channel can be connected to the combustion chamber The feeding channel is connected, and the feeding channel is arranged obliquely; a sleeve is arranged outside the feeding channel, and a closed annular cavity is formed between the inner wall of the sleeve and the outer wall of the feeding channel, and is placed in the annular cavity The side wall of the inner feeding channel is provided with a number of through holes from the outer wall to the inner wall. The air inlet of the sleeve is connected to an air duct. The end of the air duct is provided with a fan, and the gas is introduced into the ring through the air duct through the fan. In the cavity, enter the feeding channel through the inclined hole. The invention has the advantages of good anti-blocking performance, high feeding efficiency, more complete combustion of biomass particles, simplified structure, reduced 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., which are a huge renewable resource. If it is unreasonably disposed of (disposal, incineration), it will not only cause energy Waste has also brought about increasingly obvious environmental problems such as air pollution. A few days ago, biomass burners provide the energy required for production by burning the heat generated by biomass. It is a promising biomass energy utilization technology that has gradually been 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 traditional bio...
