Energy-saving type biomass fuel furnace

Abstract

The invention discloses an energy-saving type biomass fuel furnace. The energy-saving type biomass fuel furnace comprises a furnace body. The furnace body comprises an inner furnace body and an outerfurnace body. The inner furnace body is arranged in the outer furnace body in a sleeving manner. A rotatable grate is rotatably and vertically arranged in the inner furnace body by a rotary shaft. Therotatable grate comprises a plurality of fuel pallets which are sequentially arranged on the rotary shaft at intervals along the axial direction. Pared fins are symmetrically arranged at two sides ofthe rotary shaft in a spiral-shaped manner and penetrate the fuel pallets in sequence. One end of a pneumatic biomass powder feeding pipe is arranged in the way of penetrating the furnace body, extending to the fins and exactly facing the fins. A biomass particle feeding port is arranged at the top of the furnace body. A mode water-cooling wall is arranged on the side wall of the furnace body. Aslag collecting groove is arranged at the bottom of the rotatable grate in a detachable manner. A plurality of circulation ports are uniformly arranged on the side wall which is closed to the bottom of the inner furnace body at intervals in an annular manner. The energy-saving type biomass fuel furnace further comprises a smoke exhausting port and a base. The energy-saving type biomass fuel furnace is capable of mixing and burning biomass powder and biomass particle fuel sufficiently, full in combustion, high in heat utilization rate and good in energy conservation and environment protection.

Description

technical field [0001] The invention relates to the technical field of environmentally friendly fuels, in particular to an energy-saving 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 environmentally...

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
