Embodiment describes the utility model in detail below in conjunction with accompanying drawing.

Fig. 1, body of heater (1), ventilating opening (2), heat-insulation layer (3), fire door (4), furnace bottom (5), burner hearth (6), burner hearth internal layer (7), burner hearth skin (8), cavity (9), brushwood inlet (10), fire bars (11), combustion chamber (20), main burner (12), secondary burner (13), table (14), oven opening (15), chimney (16).Fig. 2, burning firewood flue (17).Fig. 3, burning straw grass flue (18), ignition chamber (19).The utility model designs according to the kerosene stove gasification principle, and body of heater (1) adopts iron sheet, and body of heater, furnace bottom are one.Two ventilating openings (2) communicate with the cavity (9) of burner hearth, pass heat-insulation layer (3) to the body of heater outer surface, heat-insulation layer (3) adopts fine earth or other insulation material, and fine earth or insulation material are put between furnace chamber skin (8) and the body of heater (1), forms heat-insulation layer.Fire door is opened the upside in furnace bottom (5), with main burner (12), brushwood inlet (10) on an axis.Burner hearth internal layer of the present utility model (7) first half is to be made by the porous sieve shape iron sheet of φ 3mm, and Lower Half is combustion chamber (20).Burner hearth skin (8) is made by the atresia iron sheet, is a confining bed.The burner hearth ectonexine is cavity (9) apart from 12mm between the inside and outside layer, and cavity (9) is by 180 ° of placements of iron pipe left-right symmetry of two φ 30mm, and cavity (9) communicates with body of heater atmosphere outward.Brushwood inlet (10) is opened the top in fire bars (11).In order to increase function of the present utility model, flue is designed to two kinds, and a kind of is to burn firewood flue (17), and another kind is to burn straw grass flues (18).Burn firewood and made by the iron cylinder of the sieve shape aperture that has φ 3mm with flue (17), divide three kinds of models, No. 1 courage is adorned 0.6 kilogram in firewood, and No. 2 courage is adorned 0.45 kilogram in firewood, and No. 3 courage is adorned 0.3 kilogram in firewood.Can select the flue of different model for use according to cooking what of food.Burning the straw grass is to be made by the iron sheet cylinder with holes of two different-diameters with flue (18), and little cylinder (19) is an ignition chamber, before lighting, places faggot 20-50 gram earlier in ignition chamber, then flue is put into burner hearth and lights a fire.Convenient in order to exchange flue for, burner hearth (6) and flue have certain interval between (17,18), are 10-12mm.Table of the present utility model (14) is the iron sheet platform, and main burner (12) is positioned at the middle part of table, and secondary burner (13) is positioned at the right side of table, and baking box (15) is positioned at the left side (also can not establish baking box) of table, and chimney (16) is positioned at the upper right corner of table.Can sit the aluminum pot of 24-32 centimetre on the major-minor burner, also can be with 42 centimeters sharp floor iron pot.Three mouths can utilize a burning things which may cause a fire disaster to work simultaneously.

Operation principle of the present utility model is: according to kerosene stove gasification principle firewood or careless when burner hearth bottom burns, flame is by upper furnace and flue, make the temperature of burner hearth and flue bring up to 400-600 ℃ rapidly, reach gasification temperature, the fuel gas of faggot in 400-600 ℃ temperature slit by the time reached spontaneous combustion.Burning the faggot fire box temperature can not balance, when temperature hang down, and the oxygen abundance, the firewood in the ignition chamber burns, and the straw grass is lighted.When temperature raises, ignition chamber's anoxic, firewood does not have flame from breath, reaches automatic adjusting.The flame operation passage of this stove is: discharged from chimney (16) then by baking box (15) to secondary burner (13) by main burner (12) to baking box (15) again.If without baking box, flame is discharged from chimney by main burner (12) to secondary burner (13) again.As need not secondary burner (13), flame be discharged from chimney (16) then by main burner (12) to baking box (15).Because this stove has enlarged the contact area of flame with pot, has set up two and has used burner, flame can be reused, thereby improved the thermal efficiency, accomplished simultaneously a fire is used more.

Compared to existing technology, the utlity model has following advantage:

1, thermal efficiency height, a fire is multiplex, saves the energy;

2, cook the time 1/2 than common stove and accessory saving;

3, reasonable in design, the scope of application is extensive.
