Biomass pellet fuel burner

Abstract

The invention relates to a biomass pellet fuel burner, comprising a casing, wherein a hearth is arranged in the casing; a feeding hopper communicating with the hearth is arranged at the upper part ofthe the casing; an igniter with a nozzle extending into the hearth is also arranged on the casing; and an ash outlet communicating with the bottom of the hearth is arranged at the lower part of the casing; further comprising a fan horizontally arranged on the casing and a flame spraying component horizontally arranged on the casing to spray flame generated by combustion in the hearth out of the hearth; an air outlet pipe of the fan communicates with the hearth, an air inlet pipe communicates with the outside, and the flame spraying component is positioned in front of an air outlet pipe of thefan. In the invention, 1) the characteristic of fast combustion of biomass pellet can be met by only adding enough biomass pellet fuel into the feeding hopper instead of multiple feeding; 2) the flameis sprayed out through the horizontally arranged flame spraying component, so that the flame cannot jump up to a high place, and the spraying direction is fixed, so that adverse effects on surrounding operators and the environment cannot be caused.

Description

technical field [0001] The invention relates to the technical field of biomass particle fuel combustion devices, in particular to a biomass particle fuel burner. Background technique [0002] Biomass pellet fuel is a new type of energy source. It is made of biomass raw materials such as agricultural straw, wood chips, and branches through crushing, granulation, and drying. It has excellent characteristics such as uniform particles, fast combustion, and less ash. [0003] When using biomass pellet fuel to provide heat energy, it needs to be added to the combustion device for combustion to generate heat. [0004] The devices in the prior art often cannot adapt to the characteristics of rapid combustion of biomass pellet fuel, and the following problems may occur: [0005] 1) Multiple feeds are required to meet the requirements of rapid combustion; [0006] 2) The flame produced by the combustion will rise very high, which will easily endanger the surrounding operators and th...
