Sleeve vertical biomass fuel furnace

Abstract

The invention discloses a biomass fuel furnace with a vertical type sleeve. The biomass fuel furnace comprises a furnace body, a fire grate, paired fins, a pneumatic biomass powder feeding tube, a biomass particle feeding port, a mode water cooling wall, a slag collecting tank, a plurality of circulation ports, a smoke outlet and a base, wherein the furnace body comprises a first furnace body anda second furnace body; the second furnace body is arranged outside the first furnace body in a sleeving mode; the fire grate is vertically arranged in the first furnace body in a rotatable mode through a rotating shaft; the fire grate comprises a plurality of fuel trays, and the fuel trays are sequentially arranged in a spaced manner in the axial direction of the shaft; the paired fins are spirally and symmetrically arranged on the two sides of the shaft and penetrate through the multiple fuel trays in sequence; one end of the pneumatic biomass powder feeding tube penetrates through the furnace body and extends to the position opposite to the fins; the biomass particle feeding port is formed in the top of the furnace body; the mode water cooling wall is arranged on the side wall of the furnace body; the slag collecting tank is detachably arranged at the bottom of the fire grate; and the multiple circulation ports are arranged on the position, close to the bottom of the first furnace body, of the side wall in an annular and uniformly spaced mode. According to the biomass fuel furnace with the vertical type sleeve, the biomass powder and the biomass particle fuel can be fully mixed and combusted, combustion is sufficient, the heat utilization rate is high, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of environmentally friendly fuels, in particular to a sleeve vertical biomass fuel furnace. Background technique [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 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 environmentall...

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
