Problems solved by technology

[0002] At present, with the massive consumption of non-renewable energy such as coal, oil, and natural gas, the shortage is increasing, and the use of traditional combustion methods will also cause environmental pollution. As a renewable energy source, biomass materials are receiving more and more attention from the society, but , the current biomass gasification technology only stays in the use of gasifiers to produce combustible gas for daily cooking, which greatly limits the application and development of biomass gasification technology
At present, environmentally friendly boilers burning renewable energy granular biomass are being widely promoted and applied at home and abroad, but the existing biomass boilers still have problems such as insufficient combustion, large smoke, not environmentally friendly, low thermal efficiency, and inconvenient maintenance. Especially in the combustion process, because the biomass boiler contains a lot of chlorine and alkaline substances, the fly ash particles of these substances are bonded to the boiler body, causing serious corrosion of the boiler, which makes the boiler unable to operate within a heating period use

Abstract

The invention discloses a biomass fuel boiler with a rotatable fire grate. The biomass fuel boiler comprises a furnace body, wherein the furnace body comprises a first furnace body and a second furnace body which are arranged in a sleeved mode; the rotatable fire grate, wherein the rotatable fire grate is vertically arranged in the first furnace body in a rotating mode through a rotating shaft, the rotatable fire grate comprises multiple fuel trays, and the fuel trays are sequentially arranged in the axial direction of the rotating shaft at intervals; a pair of fins, wherein the pair of fins are spirally and symmetrically arranged on two sides of the rotating shaft, and sequentially penetrate through the multiple fuel trays; and pneumatic biomass powder feeding pipes, wherein one ends of the pneumatic biomass powder feeding pipes penetrate through the furnace body and extend to be opposite to the fins. A biomass particle feeding hole is formed in the top part of the furnace body; a mode water cooling wall is arranged on the side wall of the furnace body; a slag collecting tank is detachably arranged at the bottom part of the rotatable fire grate; multiple circulating ports are annularly and uniformly arranged on the side wall, close to the first furnace body, of the bottom of the second furnace body at intervals; and the biomass fuel boiler further comprises a smoke outlet anda base. According to the biomass fuel boiler, biomass powder and biomass particle fuel can be fully mixed and combusted, combustion is sufficient, the heat utilization rate is high, and energy-savingand environment-friendly effects are achieved.

Description

technical field [0001] The invention relates to the technical field of environmentally friendly fuels, in particular to a biomass fuel boiler with a rotary grate. Background technique [0002] At present, with the massive consumption of non-renewable energy sources such as coal, oil, and natural gas, they are becoming increasingly scarce, and the use of traditional combustion methods will also cause environmental pollution. Biomass materials, as a renewable energy source, are increasingly valued by the society, but At present, biomass gasification technology only stays in the use of gasifier to produce combustible gas for daily cooking, which greatly limits the application and development of biomass gasification technology. At present, environmentally friendly boilers burning renewable energy granular biomass are being widely promoted and applied at home and abroad, but the existing biomass boilers still have problems such as insufficient combustion, large smoke, not environ...
