An anti-coking biomass pellet burner

Abstract

The invention provides an anti-coking biomass particle combustion engine and belongs to the field of combustion equipment. The anti-coking biomass particle combustion engine comprises a combustion engine body, an air bag and a feeding mechanism, wherein a charging screw rod and a charging screw rod feeding pipe in the feeding mechanism penetrate through the air bag to be connected to a hearth of the combustion engine body; a furnace bridge in the combustion engine body is a round furnace bridge; an arc-shaped sawtoothed slag-removing knife is welded on the front side of the furnace bridge; and the middle part of the furnace bridge is connected with a furnace bridge rotating shaft. The biomass combustion engine drives the round furnace bridge arc-shaped sawtoothed knife through a furnace bridge fixing screw to rotate and removes slag through sprocket wheel transmission and rotation to crush combustion ash before the combustion ash is coked. Tornado formed at a furnace bridge arc-shaped cyclone airflow hole enters a fire spraying orifice along with smoke flame to perform combustion again, so that the anti-coking biomass particle combustion engine eliminates the coking hidden danger, is convenient to clean and continuous in operation, achieves an ideal effect, enlarges the applicable range of the biomass combustion engine fuel and is favorable for popularization and application of the biomass combustion engine.

Description

technical field [0001] The invention belongs to the field of combustion equipment, and relates to a biomass burner, in particular to an anti-coking biomass particle burner. Background technique [0002] Biomass burner is a kind of biomass semi-gasification automatic control burner, and it is a biomass pyrolysis burner that uses biomass particles as fuel. Biomass burners have the advantages of high thermal efficiency and low smoke exhaust pollution. The application abroad began in the 1980s, and countries such as Sweden, Denmark, Austria and Germany have certain applications. There are still few researches on biomass burning equipment in our country. It has only begun to research, produce and put into use in recent years. It has not yet reached large-scale application. The main reason is that there are many problems in domestic biomass burning equipment, which are mainly reflected in the following two aspects : On the one hand, the fuel of the biomass burner has a narrow app...
