Description

Regeneration biological matter gasification combustion furnace

Technical field

The utility model relates to life use stove, and particularly a kind of regeneration biological matter gasification combustion furnace is fit to rural area and mountain area and adopts.

Background technology

As everyone knows, at present used kitchen range is cooked still based on brick in many rural areas of China and mountain area, with firewood, adopt regeneration biological matter such as bar, hay, leaf, branch and make fuel.Put living beings in flue ignition from charge door during use, the needed air that burns enters in the flue through stove Gate from charge door and ash collection slot, and the cigarette that is produced is discharged outside the room by chimney from the cigarette groove of burner.The ash that the burning back produces is fallen in the ash collection slot through stove Gate.The kitchen range minor structure of this traditional type is very simple, but the thermal efficiency is very low, its structural design is not being considered living beings problem of completing combustion whether in stove at all, therefore can produce in use that not have clean-burning gas in a large number be that black smoke is discharged inside and outside the house, not only waste heat energy, contaminated environment, also human body skin and eyes are damaged when serious.There were indivedual enterprises to develop some energy-saving cookings in recent years, hope improves the thermal efficiency by the biomass burning briquetting, reduces environmental pollution, but because design is unreasonable, great majority also adopt down-firing, have weak points such as difficult, on fire slow, Pintsch process weak effect of igniting and calorific value are low always.Some cooking stove also adopts air blast combustion-supporting, not only wastes electric energy, but also can't resolve the low and blowdown problem of calorific value.This is the defective that always exists of prior art just.

Summary of the invention

In order to solve that the burning that present regeneration biological matter burning kitchen range exists is insufficient, calorific value is low and problem such as contaminated environment, the utility model provides a kind of regeneration biological matter gasification combustion furnace.

Above-mentioned task realizes that by this way a kind of regeneration biological matter gasification combustion furnace includes body of heater, burner.Smoke evacuation is logical, flue, fire-stop ring, stove Gate and ash collection slot, it is characterized in that; Described flue is made up of neck, upper furnace and lower furnace, the cross section of neck, upper furnace and lower furnace successively increases from top to bottom, upper furnace and neck and lower furnace and upper furnace link together by tapered slope respectively, the lower furnace lower end is connected with the ash hole of reduced cross-sectional by a back taper inclined-plane, evenly has several fresh air inlets on the tapered slope between neck, upper furnace and upper furnace and the lower furnace.

The purpose of this utility model also can take following measure further perfect:

It is circular that the cross section of described neck, upper furnace and lower furnace is preferably, and its diameter ratio is suitable with 1: 2.0～2.2: 2.8～3.2, and whole flue can be welded with steel plate.

On burner, have one and pass the horizontal auxiliary charging spout that fire-stop ring is communicated with the neck end face, so that when further feeding in raw material, can in flue, feed in raw material from assisting charging spout.

The ash rake that neither one cooperates with stove Gate below stove Gate, its control stick extends outside the body of heater, so that can in time clear up the solid grey piece of the knot of obstruction.

The rotary air register of neither one in ash hole, its control stick extends outside the body of heater, so that adjust wind supply quantity according to flue endogenous substance combustion position at any time.

Design of the present utility model is with living beings and briquettings thereof such as stalk, corn bone, straw, cotton stalk, beans stalk, cigarette stalk, dish stalk, shell, the pinecone, leaf, universe cow dungs, and powder fruit grain waits makes fuel.During use, the neck by fire door adds living beings in flue, fills it up with the back and lights a fire at the neck place, after catching fire, the living beings in the flue just are heated, from top to bottom constantly burning, thermal current rises, and cold air enters in the flue from the ash discharge oral pore and replenishes, and forms general air-flow from bottom to top.Because the design of this flue is up-small and down-big layer pyramidal structure, the large number of biological matter that stores in lower furnace is in the lower temperature state, add by regulating rotary air register control wind supply quantity, they can not be burst into flames under the cold and oxygen deficient situation, but the temperatures involved of the living beings of progressively burning above being subjected to, can constantly be subjected to thermal cracking to go out carbon monoxide, Party A's alkane and and incendivity mist such as hydrogen.These fuel gas also can not burn under anaerobic condition immediately, can only up flow.Because the structure of flue is low wide and up narrow, gas flow channel is more and more narrower and small, it is flowed increases, density increases, when these fuel gas flow to upper furnace and neck, in time obtain outside air from fresh air inlet continuous secondary and three air-supply supplemental oxygen, create condition for the burning of these fuel gas, blazed up very soon, especially arrived the neck place, the air that replenishes further increases, oxygen supply is more abundant, and is more vigorous in control pyrosphere internal combustion, realized abundant burning, Here it is, and why the utility model can allow living beings be subjected to thermal cracking, fully burning, the calorific value height, the reason that blowdown is few.Show that through preliminary test the utility model has been compared following obvious advantage with existing biomass-burning stove:

1, it is easy, on fire fast to light a fire in the employing, light a fire, and operates very simple.

2, only need before using with living beings dry just can, do not need auxiliary equipment such as pulverizer and air blast, can save electric energy, be particularly suitable for not having electricity, the mountain area of short of electricity and outlying rural area use.

3, the flue capacity is bigger, and once reinforced incendivity reached as high as 5 hours more than 1 hour, but also can be reinforced by auxiliary charging spout, need not lift pot, brings convenience to use.

4, simple in structure, need not build stove, body of heater and flue can be made with steel plate punching press and welding, are fit to industrialized mass production, and cost is low, and is easy to utilize.
