The utility model can be given full play to the burning capacity of fuel, makes full combustion of fuel, has the furnace temperature of use height, and firepower is concentrated, and thermal efficiency height does not produce advantages such as black smoke.Therefore it is big to efficiently solve traditional cooking stove smog, energy consumption high-technology problem.

Description of drawings

Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.

Fig. 1 is the structural representation of a kind of preferred implementation of the utility model;

Fig. 2 is the cutaway view of embodiment shown in Figure 1.

The specific embodiment

Fig. 1 is the structural representation of a kind of preferred implementation of the utility model, Fig. 2 is its cutaway view. in conjunction with two figure as can be known, this smoke-less power-saving gasification furnace is mainly by body of heater 2, combustion chamber 4, furnace panel 5, base 9 compositions such as grade. be provided with furnace panel 5 above the body of heater 2, furnace panel 5 centers are provided with in fire door 50. bodies of heater and are provided with drop-bottom 3, body of heater 2 bottoms are fixed on the box-like base 9, be provided with the drawer type ash bin 90 that falls in the base 9, body of heater 2 tops are provided with the flue 1 that communicates with thorax mouth 22, flue 1 bottom is provided with valve plate switch 10, flue 1 below is provided with cigarette ash road 11, this cigarette ash road 11 is communicated with the ash bin 90 that falls, be provided with charge door 6 at the middle part of body of heater 2, this charge door 6 communicates with combustion chamber 4, be provided with some air vents 20 in the bottom of body of heater 2 sidewalls, drop-bottom 3 is positioned on the air vent 20, the center of drop-bottom 3 has air inlet 30, air inlet 30 is provided with stove tooth 31, be provided with the ash port 92 relative with air inlet 30 in the center of base panel 91, constitute a vented cavity 23 between base panel 91 and the drop-bottom 3, be provided with duplex air door 7 in this vented cavity 23, combustion chamber 4 places on the drop-bottom 3 and covers air inlet 30, combustion chamber 4 is up-small and down-big taper, its wall is provided with a plurality of air vents 40, between combustion chamber 4 walls upper end and body of heater 2 sidewalls, be equipped with dividing plate 21, makes between the sidewall of the sidewall of combustion chamber 4 and body of heater 2 and form secondary air duct 8, and secondary air duct mouth 80 is arranged on the drop-bottom 3 between furnace core wall and the sidewall of the furnace body.

During fuel, duplex air door 7 is pulled out, simultaneously the valve plate switch 10 on flue 1 bottom is opened, at this moment, air inlet 30 is opened, secondary air duct mouth 80 is closed, and air enters the combustion chamber 4 through air inlet 30 from the air vent 20 of body of heater 2 sidewalls bottom, and fuel adds in the combustion chamber 4 by charge door 6, and conflagration in combustion chamber 4, temperature raises rapidly in the stove, and the flue gas that burning produces is discharged by flue 1, and its cigarette ash is fallen in the ash bin 90 by cigarette ash road 11.After temperature raises, duplex air door 7 is pushed in, simultaneously with 1 switch 10 closures on the flue, at this moment, air inlet is closed, the secondary air duct mouth is opened, air enters the combustion chamber 4 through secondary air duct 8 from the air vent 20 of body of heater 2 sidewalls bottom, at this moment have only a spot of air can enter in the combustion chamber 4, because of temperature in the combustion chamber 4 very high, and the air that enters in the combustion chamber 4 is not enough, therefore fuel is understood imperfect combustion and is generated carbon monoxide, because combustion chamber 4 is up-small and down-big taper, and because the effect of dividing plate 21, the carbon monoxide that produces can be assembled at thorax mouth 22 places, owing to can obtain a large amount of oxygen herein, therefore the carbon monoxide that produces can burn away herein, because of the fuel value height of carbon monoxide, so can produce high temperature at kitchen range mouth place, make and the utlity model has the higher thermal efficiency, the solid particle that burning produces in combustion chamber 4 because the closing of chimney valve switching plate 10, make in the combustion chamber 4 ascending airs a little less than, solid particle part in uphill process can become carbon monoxide by imperfect combustion, a part can fall to melting down in the core 4, and remaining a part of cigarette ash can drop to by the cigarette ash road 11 under the flue 1 in the ash bin 90, so the utility model can not produce flue dust.The lime-ash that burning back produces again can be smoothly space by 31 in stove tooth enter drawer type in the base 9 through the center of base panel 91 and air inlet 30 relative ash ports 92 and fall in the ash bin 90, after ashes are filled in the ash bin 90 that falls, the ash bin 90 that only needs to fall is extracted out, just can conveniently remove the ashes of ash bin 90 the insides.
