Abstract
The utility model provides a biomass boiler. The biomass boiler comprises a boiler body, a furnace hearth and a flue gas return pipe, wherein the internal wall of the furnace hearth and the internal wall of the flue gas return pipe are coated with a high-temperature resistant heat insulation material. According to the biomass boiler provided by the utility model, the internal wall of the furnace hearth and the internal wall of the flue gas return pipe are coated with the high-temperature resistant heat insulation material, so that the heat preservation effect of the boiler is effectively improved, and the utilization ratio of heat energy is effectively increased.
Description
Technical field
The utility model relates to a kind of boiler, is specifically related to a kind of biomass boiler.
Background technology
Biomass boiler be a kind of with biomass energy the boiler as fuel, it has rational in infrastructure, heating surface area is large, the thermal efficiency is high, sufficient combustion, pollution-free, the features such as low emission, all kinds of discharge indexs, lower than country's (GB13271-2001) " emission standard of air pollutants for boilers " regulation, are all to substitute electricity, fuel oil, combustion gas, coal-fired steam boiler best product.Biomass boiler burner hearth operating cost is low, can save 40%～50% operating cost than fuel oil, combustion gas, electrically heated boiler, is a kind of thermal hardware of high-efficient energy-saving environment friendly.
The fuel that biomass boiler uses is biomass fuel.Biomass fuel is environmental protection regenerative resource, is the green energy resource that the whole world is widelyd popularize; Biomass fuel can reach " zero-emission " in combustion process---without deslagging, smokelessly, also without pernicious gases such as sulfur dioxide, free from environmental pollution, carbon dioxide approaches zero-emission, is the effective way that changes weather disadvantageous changes.Alternative standard coal 0.8～1.0 ten thousand ton of every 10,000 tons of biomass fuels, reduce 160 tons of sulfur dioxide (SO2) emissions, reduce 80 tons of soot emissions, reduce 1.44 ten thousand tons of CO2 emissions.It is to utilize the discarded crops such as wood chip to make raw material through machine granulation shape, and raw material source is abundant, and burning time is long, and when overheavy firing, fire box temperature is high; Biomass fuel calorific value can reach 3700～5000 kilocalories/kg, and firepower is prosperous by force, and the thermal efficiency can reach more than 90%, far away higher than 60% of fire coal, saves mass energy.Use biomass fuel operating cost low, burning cost drops to common coal and is equal to, and is 1/6 and 1/3 of electric boiler and fuel-oil or fuel-gas boiler, has saved the simple coal-fired environment protection treating expense increasing.Fuel density reaches 0.9～1.2 ton/side, is easy to transport and stores.
Visible biomass boiler is the brand-new trial of boiler industry above, according to its burning heat-dissipating principle, on the basis of current pilot boiler, need the heat energy that further improves boiler to continue with temperature preservation and controlling, increase thermal effect utilization rate, certainly will make biomass boiler burner hearth have more wide market prospects and the huge potentiality of sending, will become the product that boiler industry updates.
Utility model content
For above problems of the prior art, the utility model provides a kind of good heat insulating, sufficient combustion, biomass boiler that thermal effect utilization rate is high.
The utility model is achieved through the following technical solutions:
Biomass boiler, comprises body of heater, burner hearth, flue gas return duct, and described inboard wall of burner hearth and flue gas return duct inwall are coated with high temperature resistance insulation material.
Described high temperature resistance insulation material is portland cement.
Described burner hearth adopts fire proofing tile and portland cement to make.
The beneficial effects of the utility model are: biomass boiler of the present utility model, by applying high temperature resistance insulation material at wall of inner container and flue gas backhaul inwall side, effectively solve boiler insulation effect, and effectively improve the utilization rate of thermal efficiency.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure: 1 is body of heater; 2 is burner hearth; 3 is flue gas return duct; 4 is high temperature resistance insulation material.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
The utility model provides a kind of biomass boiler, comprises body of heater 1, burner hearth 2, flue gas return duct 3, is coated with high temperature resistance insulation material 4 at the inwall of burner hearth 2 and the inwall of flue gas return duct 3, is convenient to increase the heat-insulating property of burner hearth 2 and flue gas return duct 3; High temperature resistance insulation material is portland cement; Burner hearth adopts the features such as fire proofing tile and portland cement are made, and it is low that fire proofing tile has cost, and high temperature resistant property is superior.
Biomass boiler of the present utility model, by applying high temperature resistance insulation material at wall of inner container and flue gas backhaul inwall side, effectively solves boiler insulation effect, effectively improves the utilization rate of thermal efficiency.
