Abstract
The utility model provides an air inlet pipe of a biomass boiler. The air inlet pipe comprises a boiler body, a furnace hearth and an air inlet pipe, wherein the outer side of the air inlet pipe is coated with a layer of heat insulating material. According to the air inlet pipe provided by the utility model, the heat insulating material is coated, and a heat insulating pad is additionally arranged, so that the condition that the surface layer of the biomass boiler cannot be smoked and baked when high temperature from a combustion chamber is transferred to the air inlet pipe can be ensured, and thus, the appearance and cleanliness of the boiler are guaranteed.
Description
Technical field
The utility model relates to a kind of biomass boiler, is specifically related to a kind of biomass boiler Gas inlet tube.
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 (GB13271-2001) < < of country 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 operating cost is low, than fuel oil, combustion gas, electrically heated boiler, can save 40%～50% operating cost, is a kind of thermal hardware of high-efficient energy-saving environment friendly.
The fuel that biomass boiler is used 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 during 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 transportation and stores.
Traditional biomass boiler is in the process of burning, and air intake vent pipe temperature is too high, and the variable color of easily being fire-cureed in casing top layer, affects biomass boiler outward appearance.
Utility model content
For above problems of the prior art, the utility model provides a kind of good heat insulating, avoid the high temperature biomass boiler top layer of fire-cureing.
The utility model is achieved through the following technical solutions:
Biomass boiler Gas inlet tube, comprises body of heater, burner hearth, Gas inlet tube, brushing one deck heat-barrier material outside described Gas inlet tube.
Described Gas inlet tube outside is provided with the heat insulating mattress of coated Gas inlet tube.
Described heat insulating mattress is asbestos pad.
The beneficial effects of the utility model are: inlet tube of the present utility model through applying heat-barrier material, set up heat insulating mattress and can guarantee from the high temperature of combustion chamber when being delivered to Gas inlet tube, the top layer that can not fire-cure biomass boiler, thereby outward appearance and the spatter property of assurance boiler.
Accompanying drawing explanation
Fig. 1 is positive overall structure schematic diagram of the present utility model.
In figure: 1 is body of heater; 2 is burner hearth; 3 is Gas inlet tube; 4 is heat-barrier material; 5 is heat insulating mattress.
The specific embodiment
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 Gas inlet tube, as shown in Figure 1, comprises body of heater 1, burner hearth 2, Gas inlet tube 3, at Gas inlet tube 3 outside brushing one deck heat-barrier materials 4, can effectively reduce the temperature of Gas inlet tube; In the outside of Gas inlet tube 3, be provided with the heat insulating mattress 5 that is coated on Gas inlet tube 3, can more effectively avoid the impact of heat energy on body of heater top layer; Heat insulating mattress is asbestos pad, the good seal performance advantage of asbestos pad, the superior scope of application of decay resistance of asbestos pad.
Inlet tube of the present utility model through applying heat-barrier material, set up heat insulating mattress and can guarantee from the high temperature of combustion chamber when being delivered to Gas inlet tube, the top layer that can not fire-cure biomass boiler, thus guarantee outward appearance and the spatter property of boiler.
Claims (3)
1. biomass boiler Gas inlet tube, comprises body of heater, burner hearth, Gas inlet tube, it is characterized in that brushing one deck heat-barrier material outside described Gas inlet tube.
2. biomass boiler Gas inlet tube according to claim 1, is characterized in that described Gas inlet tube outside is provided with the heat insulating mattress of coated Gas inlet tube.
3. biomass boiler Gas inlet tube according to claim 2, is characterized in that described heat insulating mattress is asbestos pad.
