Abstract

The utility model discloses a multi-fuel semi-gasification cooking and heating furnace, comprising a fuel bunker (1), a reversal combustion zone (2), an ash bucket (3), a secondary air device (4), a metal liner (5), a main cooking port (6), an assisting cooking port (7), a smoke outlet (8), an oven (9), a radiating hole plate (10) and a hearth (11). Fuels are fed into the fuel bunker (1) from a feeding door, and then dried, desulfurized and carbonized in the fuel bunker (1), and then fed into the high temperature reversal combustion zone (2) to be combusted under the support of secondary air, and the smoke is exhausted into the outside atmosphere through a flue. The fuels are combusted without the support by a fan and can be automatically combusted with the air from the opened ash bucket (3) and stop combustion when the ash bucket (3) is closed. The utility model has the advantages of simple structure, comprehensive functions, easy manufacture, convenient operation and maintenance and low cost.

Description

Many fuel half gasification radiator of cooking a meal

One, technical field

The utility model product belongs to a kind of stove and accessory, is specifically related to a kind of herdsman with efficient half-gasification multifunctional biomass furnace.

Two, background technology

Because herdsman's rule of life and life style have exclusive national characteristic, requirement and ordinary student material (or fire coal) hot-water boiler of stove and accessory there is very big difference.Biomass fuel is exactly that bar, leaf, rhizome (being mainly straw) crops pulverized after mechanical compress is shaped fuel (a bar-shaped briquetting), boiler combustion is provided, biomass energy belongs to regenerative resource, have energy-conservation, combustion cleaning, low pollution emission and operating cost and be lower than advantages such as conventional energy resource, especially being fit to the rural area uses, help improving the life in the countryside environment, improve the life of farmers quality, produce market has a extensive future.

At present, biomass fuel boiler is used for cooking or heating more, and fuel is briquetting or particle, and fuel palpus producer provides or buys to specialized factory.Do not supply or the too high user of price is reluctant to buy as producer, the boiler oil supply will be a problem.Design the herdsman who satisfies above-mentioned specification requirement is very necessary with efficient half gasified bio-matter stove for this reason.

Three, summary of the invention

According to background technology, the purpose of this utility model is to avoid above-mentioned deficiency, it is extensive that it is suitable for fuel, animal residues such as cow dung, sheep excrement can burn, again can the biomass burning briquetting, fuel such as firewood, corncob, every kind of fuel can independent burning, gravity-flow ventilation can realize half gasification, and combustion (combustion-supporting without blower fan), heating stove and accessory metal shell provides the herdsman family heating with forms of radiation.

There are the small atmospheric boiler manufacturing of two more than ten years, research and development experience in my company, once develops the mobile counter-burning coal-fired boiler of individual layer, finds a good market so far.We in conjunction with fuel combustion characteristics such as cow dung, biomass block, need condition, by tens trial-production, test, observe, have determined present type of furnace design on this type of furnace basis.

To achieve these goals, the utility model is achieved through the following technical solutions:

A kind of many fuel half gasification radiator of cooking a meal, mainly by Bunker (1), instead burn district (2), ash bucket (3), overfire air device (4), metal courage (5), main cooking mouth (6), pay cooking mouth (7), outlet flue (8), baking box (9), heat radiation orifice plate (10), the kitchen range top (11) form.Fuel is knocked down Bunker (1) from the filler door, finishes drying, desulfurization, carbonization process in Bunker (1), enters the anti-district (2) of burning of high temperature and burns, and meets combustion law.The anti-district (2) of burning of high temperature builds defending of forming by laying bricks or stones by high-temperature flame-proof mud to fire the chamber, fuel is cracked into fuel gas such as carbon monoxide, hydrogen, methane after by high-temp combustion, in the combustion process, during flame process overfire air device (4), the oxygen that overfire air device (4) provides will not burn full combustion of gas.During normal combustion, can be observed the blue look flare of secondary air hole from anti-burning district (2) top flame-observing hole, flame is limpid, chimney is over-emitting black exhaust not, installs main cooking mouth (6) on overfire air device (4) additional, can be used for cooking, heats up water, cooks etc., above flue, install additional and pay cooking mouth (7), can be used for heating sour milk etc., below flue, be provided with baking box (9), but foods such as baked steamed bread, Ipomoea batatas.Flue gas is entering atmosphere through behind the horizontal flue.Four meters of chimney height, the chimney draft impels flow of flue gas, and promotes burning.Combustion-supporting without blower fan, make ash bucket (3) and enter air and get final product automatic combustion, close ash bucket (3) and promptly enter the state of banking up a fire.

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, the utility model incendivity cow dung, sheep excrement, biomass block, firewood, corncob and bituminous coal, and can realize the quick switching of fuel.

2, the utility model fuel is finished drying, desulfurization, carbonization process in Bunker, meets combustion law.Filler incendivity 2-3 hour meets general herdsman and cooks the time.

3, smokeless combustion during the utility model normal combustion, flue gas lingemann blackness be less than the I level, and flue dust and gas concentration of emission all reach or be better than national environmental standard.

4, the utility model is gravity-flow ventilation, and can realize half gasification of burning, sufficient combustion, and flame is limpid.Boiler thermal output is greater than 75%.

5, the manual deashing of the utility model guarantees that flue is unimpeded, need not install cleaner additional, and the fuel saving is smokeless again, and operating cost is cheap.

6, the utility model functional diversity, but cooking, but heating is multiple functional.

7, the utility model is safe and reliable, and is easy and simple to handle, economic and practical.
