Abstract

The utility model discloses a coal gasification combustion furnace, which comprises a furnace main body (1) which is also used as a heat-insulating layer (3), a gas kitchen range (4) and a water interlayer sleeve (2). Water in the water interlayer sleeve (2) can be boiled through igniting fuel in a fuel tank (11) to produce steam, and steam gets into an air inlet (6) through a steam pipeline (5), air and steam get into the fuel tank (11), and coal, wind and steam which are burnt are combined into one body to produce normal-pressure combustible gas, when coal ash is cleaned, an ash dropped pillar (7) is pushed, and ash drops in an ahs dropped disc (10).

Description

Coal gasifying combustion stove

[technical field]

The utility model relates to a kind of coal gasifying combustion stove, body of heater double as heat-insulation layer especially, and the water interlayer cover, flexibly connects the coal gasifying combustion stove that stove canopy, gas-cooker are formed at fuel bore.

[background technology]

People cook food, heat up water, and cooking stove is the thing of using always, use for convenience coal stove, honeycomb briquette stove to have occurred, coal stove in the market is as burning faggot, and the many and flue dust of feed consumption scatters and contaminated environment, and not a kind of honeycomb briquette stove firepower is slow, calorific value is low, and the coal gas flavor scatters and contaminated environment.

Existing Coal Gasification Technology is large-scale, and the enterprise that can only give gas uses, and the people does not rise with home-use.

[summary of the invention]

The purpose of this invention is to provide a kind of normal pressure fuel gas that belongs to, easy to use, the just formula coal, the charcoal that are fit to individual, family, restaurant's use, honeycomb briquette gasification, and combustion cooking stove, coal burns much cleaner through gasification again, can also energy savings, only need the push-and-pull grey bar that falls just can make coal ash fall into ash-pan during cleaning coal ash.

To achieve these goals, the utility model coal gasifying combustion stove is made up of furnace body double as heat-insulation layer, water interlayer cover, gas-cooker, fuel bore fuel body of heater waste heat energy on fire is boiled and produce steam the water in the water interlayer cover, steam enters air inlet by jet chimney, wind and steam enter fuel bore through the stove canopy, fuel and wind and steam are integrated and produce combustible gas, and combustion gas directly reaches gas-cooker by the gas outlet.Furnace body and stove canopy be for flexibly connecting, and the push-and-pull grey bar that falls just can rotate the stove canopy during cleaning coal ash together with lime scraping knife, and coal ash falls into ash-pan by the stove canopy, ash-pan is taken out just finished deashing.

After adopting such structure, coal or honeycomb briquette through gasification after burning again, firepower is bigger, calorific value is higher, the body of heater waste heat uses through water steam, fuel burns more fully, can energy savings, soot emissions still less, and are much cleaner.

[description of drawings]

Below in conjunction with drawings and Examples the utility model is described in further detail.

Accompanying drawing is the vertical section structural map of the utility model embodiment.Heat-insulation layer in the drawings, 1, body of heater, 2, the water interlayer cover, 3,, 4, gas-cooker, 5, steam pipeline, 6, air inlet, 7, grey bar falls, 8, Lu Peng, 9, lime scraping knife, 10, ash-pan, 11, fuel bore, 12, gas outlet, 13 fire-resistant mud layers, 14, glass visits the water window, 15, filler, 16, valve, 17, charge door, 18, charge door spiral cover, 19, discharge outlet, 20, the air intake flap.

[specific embodiment]

Coal gasifying combustion stove shown in the figure is made up of body of heater 1 double as heat-insulation layer 3 and water interlayer cover 2 and gas-cooker 4, gas-cooker 4 is put on gas outlet 12, body of heater 1 is flexible connection with stove canopy 8, and stove canopy 8 is connected one with lime scraping knife 9, the center that the grey bar 7 that falls is inserted in stove canopy 8.Ash-pan 10 is under stove canopy 8, and ash-pan 10 sides are air inlets 6, and air inlet 6 is connected steam pipeline 5.Filler 15 enters water interlayer cover 2 by valve 16, and water interlayer cover 2 is provided with glass and visits water window 14, and charge door 17 leads directly to into fuel bore 11 on body of heater 1.Charge door 17 has the screw thread coupling of screw thread and charge door spiral cover 18.Fuel bore 11 liners adopt fire-resistant mud layer 13, the hot water in the discharge outlet 19 convenient water intaking interlayer covers 2.

Put into several from charge door 17 earlier during use and be with fiery charcoal or coal cinder to fuel bore 11 bottoms, and then pour coal into, reinforced many more burning times are long more, but should not fill it up with charge door 17.Build charge door spiral cover 18, from air inlet 6 just burnings of blowing fuel, discharge water into filler 15 again, water completely arrives glass and visits water window 14, shuts valve 16, and gas-cooker 4 has flame normally to use after several minutes.

Regulate firepower: control intake size can reach the purpose of regulating firepower.

Postcombustion: generally speaking, flammable about 5 hours of 5 kilograms of fuel, when gas-cooker 4 flames redden, expression fuel bore 11 few material, as continue to use the need postcombustion, and at first close air inlet 6 and open valve 16, open charge door spiral cover 18 again, add fuel from charge door 17, again valve-off 16 and open air intake flap 20.

Stop using: close air inlet 6, open valve 16, can stop aerogenesis.

Bank up a fire: fire-sealing time can reach 1-3 days, and the method for banking up a fire is same as and stops using, if fuel bore 11 fuel should add fresh fuel less.

Reuse: being same as postcombustion, is because the coals ash too much stops up gas circuit in the fuel bore 11 as firepower slowly, fall grey bar more than 7 times of push-and-pull, and the coal ash falls into ash-pan 10, just can normally use.

Certainly, steam pipeline, charge door and gas-cooker and gas outlet can be installed in other positions of body of heater, also can draw body of heater to combustion gas with pipeline and use outward.Body of heater, Lu Peng, lime scraping knife, gas-cooker, steam pipeline also can use other structures, as circle, half elliptic, square, triangle or other suitable shapes.The conversion of sample all drops within the utility model protection domain.
