Description

Biological particles combustion gasification stove

Technical field

The utility model relates to stove, and particularly a kind of biological particles combustion gasification stove is fit to cities and towns, rural area and mountain area and uses.

Background technology

The crowd can be known, and at present the cook cooking stove of usefulness of the many rural areas of China and mountain area still becomes with brick, with biomass as fuel such as firewood, straw, hay, leaves.This furnace construction is very simple, but the thermal efficiency is very low, and its structure is not considered living beings clean-burning problem whether in stove at all, and black smoke is a lot, not only wastes heat energy, but also contaminated environment, even human body skin and eyes are damaged.Some company developed some and utilized sawdust in recent years, made the combustion gasification stove of fuel after straw is pulverized, but immature because of technology, used complexity, and was also combustion-supporting with air blast, not only can't resolve the black smoke problem, and expended many electric energy, can't apply.I had once applied for a utility model patent that denomination of invention is " a regeneration biological matter gasification combustion furnace " in 2008 to Patent Office of State Intellectual Property Office, had improved the thermal efficiency greatly, significantly reduced the generation of black smoke.Yet the instructions for use that this stove can't the adapted biomass granular fuel is difficult to normal combustion and operation.This is the problem that prior art still need solve.

Summary of the invention

In order to solve the combustion problem of biological particles, the utility model provides a kind of sufficient combustion on the basis of test of many times, the high and easy to operate biological particles combustion gasification stove of calorific value.

Above-mentioned task realizes by this way: a kind of biological particles combustion gasification stove, include body of heater, burner, fire-stop ring, divide fire ring, smokejack, the fire door neck, flue, grate, store up grey incubator, ash hole, rotary type air register and dust collecting box, it is characterized in that: be to link together between fire door neck and the flue with a Taper Pipe shape transition piece, on Taper Pipe shape transition piece, evenly be provided with several fresh air inlets, on the Taper Pipe shape transition piece of fire door neck bottom, be provided with an adjusting rod that extends to outside the body of heater, below the adjusting rod at corresponding fire door neck place, be provided with one and be not more than 3 millimeters valve plates with fire door neck fit clearance.

The utility model also can take following measure further perfect:

Described flue is preferably up-small and down-big Taper Pipe shape, makes with refractory material, is beneficial to burning and heat-insulation and heat-preservation.

Whole of described fire door neck and Taper Pipe shape transition piece cylinder iron cast or steel plate is welded.

Valve plates is provided with an elastic positioning pin in the grip of adjusting rod, so that can be fixed on a certain position convenient the adjusting.

On burner, also have a branch fire ring, use with the pot that adapts to different sizes.

This combustion gasification stove is to use like this: this stove has two kinds of sell goods, and a kind of is that smokejack and smoke exhaust ventilator link together, and mainly uses for the town dweller; Another kind is not to be with smoke exhaust ventilator, during use smokejack is connected with chimney, mainly uses for rural area and hillman.This stove is opened reinforced passage with perpendicular the putting of valve plates earlier in use, add particulate biomass fuel in from the fire door neck toward flue, then light the biomass fuel on upper strata with paper, on burner, put iron pan then, this moment is under the draft effect of chimney or smoke exhaust ventilator, it is combustion-supporting that air enters flue from ash hole, thermal current that produces and unburnt gas discharge out of the furnace from smokejack through conical transition connector and fire door neck again, after 5 minutes air register is closed, make and be in anaerobic condition in the stove, run into the extraneous air that enters from fresh air inlet when unburnt gas process conical transition connector that is produced and fire door neck, obtain secondary oxygen supply fully burning immediately, produce blue flame, so calorific value is than higher, black smoke also seldom.After the utility model is provided with valve plates, just in time cooperate in the time of above valve plates forwards adjusting rod to,, almost flue is sealed because the gap is very little with the fire door neck; And when below valve plates forwards adjusting rod to, valve plates is left the fire door neck, and bigger gap is arranged between the conical transition connector, a large amount of hot gas and unburnt gas just can enter in the fire door neck, if valve plates has gone to certain angle, the gas that enters the fire door neck just increases, this shows, just can rationally control the flow that burning gases enter the fire door neck by regulating rotary type air register and valve plates, make secondary oxygen-supplying amount and burning gases reach optimum Match, realize fully burning, progressive part that the present utility model point produced that Here it is.Therefore, people in use, as long as conscientiously adjust the rotary type air register and valve plates just can obtain desirable combustion efficiency.

In sum, the utility model has following advantage:

1. adopt and go up igniting, igniting easily, and is on fire fast, simple to operate.

2. the once reinforced incendivity long period, the convenient use.

3. rational in infrastructure, sufficient combustion, the calorific value height, blowdown is few, and especially superior is to make burning reach comparatively perfect condition by the adjusting of rotary type air register and valve plates.

4. the very cheap biomass granule fuel of incendivity is easy to apply, and therefore, the utility model is the combustion furnace of the most suitable use biomass granule fuel up to now.
