Abstract
The invention discloses a high-efficiency and low-emission biomass water heater, which comprises a furnace body and a chimney, wherein the chimney is arranged at the top of the furnace body; a hearth, a double-ring combustor, a heated tube and a flame path tube are sequentially arranged in the furnace body from bottom to top; the hearth is made of a fireproof material; a feeding hole with an open-close cover is formed in the side wall of the hearth; the bottom of the hearth is an ash outlet, and the top of the hearth is a gas outlet; an ash receiving hopper is arranged below the ash outlet; the double-ring combustor is arranged on the gas outlet; the heated tube is transversely arranged above the double-ring combustor; the inlet and the outlet of the heated tube are connected to the outside of the furnace body; the flame path tube is vertically arranged above the heating tube; and an air distribution channel is arranged at a position, as high as the double-ring combustor, on the furnace body. The high-efficiency and low-emission biomass water heater can effectively perform full semi-vaporizing combustion, and the heated tube and the flame path tube are arranged in the furnace body, so that heating area can be increased. Under the draught of the chimney without a blower and the like, combustible gas, namely flame can be spread over the whole furnace body, so that heat efficiency is greatly improved.
Description
Technical field
The present invention relates to boiler, especially a kind of hot-water boiler take living beings as fuel.
Background technology
Biomass fuel belongs to renewable resource, and NATURAL DISTRIBUTION is wide, and aboundresources is a kind of low-cost resource of alternative fire coal.As civilian biomass boiler, require boiler itself simple in structure, the volume less.
A kind of biomass fuel boiler, described in Chinese utility model patent 200820090959.9, biomass fuel combination relates to boiler, is specifically related to a kind of civil boiler take living beings as fuel.It comprises body of heater and heat exchanger, and heat exchanger is made of shell and smoke pipe, and shell wraps between smoke pipe periphery and smoke pipe and forms water layer, and heat exchanger is fixed on the body of heater top, and body of heater is common stove.It is little, simple in structure that it has a volume, is fit to civilian advantage, but uses traditional combustion system, and efficiency of combustion is not high.
With the similar a kind of biomass molding fuel gasification combustion boiler as describing in Chinese utility model patent 200720063393.6 of technique scheme, this boiler has partly increased air blast and pay-off at burner hearth, and the Secondary Air that has increased in burner hearth distributes and automatic feeding function.Efficiency of combustion in body of heater is better.
Above-mentioned boiler combustion technology is the direct combustion burning, and this combustion system obtains heat by fuel is directly burnt, and fuel is generally coal, liquefied gas, heavy oil etc.The shortcoming one of this combustion system is that fuel availability is not high, has increased entreprise cost; The 2nd, the scarcity of having aggravated non-renewable energy resources; The 3rd, contaminated environment.
In order to address this problem, a kind of biomass gasification combustion furnace is disclosed in Chinese invention patent 200910187815.4, it is converted into the high-quality fuel gas by preheating, destructive distillation with biomass fuel, and the design by wind, Secondary Air and an air port, with the abundant mixed intensified burning of air, accomplish smokeless, dustless, no-pollution gas discharging fully.In addition, the design of underneath type spiral feed system, the further perfect global design of boiler, feeding is more scientific, greatly reduces workman's labour intensity, has improved work situation.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can improve biomass combustion efficient, and efficient low-emission biomass water heater simple in structure.
A kind of efficient low-emission biomass water heater comprises it is characterized in that the chimney at body of heater and body of heater top:
Be disposed with from the bottom to top burner hearth, dicyclo burner, heat pipe, quirk pipe in body of heater inside; Wherein burner hearth is that refractory material is made, burner hearth sidewall is provided with the charging aperture with open-close cover, burner hearth bottom is ash hole, the top is the gas outlet, has ash bucket, dicyclo burner to be installed on the top, gas outlet below ash hole, the heat pipe lateral arrangement is in dicyclo burner top, the import and export of heat pipe are connected to outside body of heater, vertically are furnished with the quirk pipe above heat pipe, and the position that is positioned at the dicyclo burner height on body of heater is provided with the air distribution passage.。
Supplementary technology scheme of the present invention is as follows:
Preferably, described air distribution passage is multichannel air distribution passage.
Preferably, the ash bucket below ash hole is drawer type ash bucket.
The invention has the beneficial effects as follows: after biomass fuel enters in burner hearth, close the parts such as charging aperture, ash bucket, freeze profile becomes the condition of anaerobism burning, under the biomass fuel anaerobic state, burning produces flammable mist, flammable mist burns at dicyclo burner place by the gas outlet, be combined with the Secondary Air of coming in by the air distribution passage at this and burn fully completely, this is half gasification, and combustion.Be equipped with heat pipe and quirk pipe in the pot body, heating surface area is strengthened.(do not need air blast etc.) under the draft of chimney, imflammable gas is that flame can be covered with whole pot body, thereby the thermal efficiency is greatly improved.
Efficient low-emission biomass water heater of the present invention has changed the high problem of boiler oil cost.One ton of biomass block cost is 400-500 unit, and the cost of one ton of coal is wanted 800-1000 unit, has improved the economic benefit of enterprise.Changed the low problem of fuel availability.With respect to traditional direct combustion mode, the present invention adopts half gasification, and combustion mode, can greatly improve the thermal efficiency of fuel.Because the direct combustion mode that half gasification, and combustion mode is compared traditional can be burnt fuel more fully, thereby has reduced the gas dischargings such as carbon dioxide, nitrogen oxide, protected environment.
Description of drawings
