Description

Energy saving and environment friendly back firing boiler
Technical field
The present invention relates to a kind of boiler, be specifically related to a kind of energy saving and environment friendly back firing boiler.
Background technology
Boiler is a kind of energy conversion, have the forms such as heat energy of chemical energy in fuel, electric energy, high-temperature flue gas, and through boiler conversion, outwards output has steam, high-temperature water or the organic heat carrier of certain heat energy to the energy of boiler input.The original meaning of pot refers to the water container heating on fire, and stove refers to the place of combustion fuel, and boiler comprises pot and stove two large divisions.The hot water producing in boiler or steam, can be directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by Steam Power Equipment, or by generator, mechanical energy is converted to electric energy again.Traditional boiler adopts directly burning type, and the fuel that is in top first burns, and the flue gas that burning produces is directly upwards drawn.Solid fuel can produce some imflammable gas when burning, and traditional this boiler, easily causes these imflammable gas, goes back unburned and just with flue gas, discharges, and burns insufficient.And traditional this boiler, the heat exchanger effectiveness of flue gas is also low.
ZL200820118627.7 Chinese utility model patent, discloses a kind of name and has been called: many fuel environmental protection energy-saving type kitchen work full heating dual-purpose stove, its structure has been comprised of body of heater, Bunker, Fan Shao district and two backhaul water pipes.Wherein: described body of heater is comprised of filler door, cold-water wall, burner hearth, fire door, ashes storehouse, cooking mouth seat and outlet flue; On the top of described Bunker, filler door is set, the surrounding of described body of heater and top arrange the cold-water wall consisting of outer courage and inner bag, and its top is also provided with cooking mouth seat and outlet flue, in the bottom of body of heater, is provided with burner hearth, ashes storehouse and fire door; In the inside of body of heater, Bunker is set from front to back according to the order of sequence, Fan Shao district and two backhaul water pipes; By high-temperature flame-proof mud, overfiren air port is built by laying bricks or stones into and is defended formation Fan Shao district, combustion chamber.The advantage of this kind of back firing boiler is: fuel completes dry, desulfurization, carbonisation in Bunker, enters the burning of high temperature Fan Shao district, meets combustion law.Fuel is cracked into the fuel gas such as carbon monoxide, hydrogen, methane after by high-temp combustion.In combustion process, during flame process overfiren air port, the oxygen that overfiren air port provides is burnt fuel gas.Yet there is following defect in this kind of back firing boiler:
1) because a large amount of flue gases flows to outlet flue by overfiren air port, thereby cause entering by outlet flue, and it is very limited to flow to the amount of oxygen of overfiren air port, this just makes a large amount of fuel gas, Fan Shao district is fully burning not, just with flue gas, discharges, and has caused the waste of the energy;
2) speed is slower during the air proper flow in flue, causes the burning velocity of fuel slower, thereby makes the efficiency of heating surface of this kind of boiler lower;
3) this kind of boiler, cannot carry out real-time monitoring to the combustion case of fuel automatically, also cannot carry out Real-Time Monitoring to water temperature in boiler simultaneously;
4) for this fuel of for example coal, after burning, still can keep its block structure, owing to limited by chamber structure, this waste residue cannot fall into ashes storehouse automatically, thereby affects the normal combustion of other fuel.
Summary of the invention
The object of the invention is to solve back firing boiler in above-mentioned prior art, Yin Fanshao district causes burning insufficient for hypoxgia, and the efficiency of heating surface is low, in the combustion case to fuel, and boiler automatically, water temperature is carried out real-time monitoring, block waste residue can not be entered automatically to the problem in ashes storehouse, provide a kind of assurance fuel combustion abundant, the efficiency of heating surface is high, can be automatically to fuel combustion situation, and in boiler, water temperature is carried out Real-Time Monitoring, and can automatically waste residue be entered to the back firing boiler in ashes storehouse.
For achieving the above object, the technical solution adopted in the present invention is as follows:
