Abstract

The utility model relates to a semi-gasification boiler, which comprises a combustion stove and a decomposing furnace, wherein the combustion stove consists of a stove body (1) and a stove bottom (2); a smoke tube (16) is formed in the stove body (1); the decomposing furnace consists of a furnace wall (3), a furnace surface (4) and a furnace bottom (5); the furnace wall (3) is provided with a feed hole (6); a downward convex conical body (7) is arranged between the stove bottom (2) and the furnace bottom (5) for partitioning the inner cavity of the decomposing furnace into an upper cavity (8) and a lower cavity (9); the conical body (7) is provided with an air vent hole (71) for communicating the upper cavity (8) with the lower cavity (9); the furnace wall (3) is provided with an air supply tube (10) for communicating the lower cavity (9); the air supply tube (10) is externally connected with a blower (11); a projection angle formed by the furnace wall (3) and the air supply tube (10) on the horizontal plane can be set between 0 and 50 degrees; and a heat-insulating material (31) can also be filled in the furnace wall (3). Through the semi-gasification boiler, energy conversion rate can be greatly improved; meanwhile, injury caused to a human body by harmful gas and high temperature can also be effectively avoided.

Description

A kind of half-gasification oven

Technical field

The utility model relates to be produced and the used stove of living, and refers in particular to half-gasification oven.

Background technology

Present vast southern rural area and factory building are used for the employed stove of burning boiler; But owing to make simple, coarse, distinguished and admirable reason such as not smooth makes that burning is insufficient; Form a large amount of poisonous dust and smog, cause the health injury in various degree that vast southern rural area is often passed in and out the people in kitchen.

The utility model content

For making the stove burning more abundant, reduce the generation that stove burns pollutant to greatest extent, the utility model adopts following technical scheme to solve: a kind of half-gasification oven; Comprise burning kitchen range and dore furnace, said combustion furnace is formed at the bottom of by stove and kitchen range, is connected with chimney in the stove; Said dore furnace is made up of furnace wall, boiler face and furnace bottom; The furnace wall is provided with charging hole, and the bullet that is provided with downward protrusion at the bottom of the said kitchen range and between the furnace bottom is divided into upper cavity and lower chamber with the dore furnace inner chamber, and bullet is provided with passage and is communicated with upper cavity and lower chamber; The furnace wall is provided with ajutage and is communicated with lower chamber, and ajutage connects air blast outward.The half-gasification oven of this structure is when the continuous air blast of air blast gets into lower chamber, because the setting of bullet; Can between lower chamber, form one rotation wind, make the combustible substance in the upper cavity fully burn, simultaneously because the bullet protrusion is downward through the aperture on the bullet; Incendiary material can be effectively gathered, under the rotation wind action, temperature can be promoted very soon; Reach the purpose of vaporising fuel; Significantly reduce in this dust that forms simultaneously and smog, and dust and the smog of the overwhelming majority will be through the chimney discharges, be reduced to minimum the infringement of human body.

Further, said stove is made up of kitchen range circle, interior firestopping ring and outer firestopping ring, and its medium mess circle is arranged on interior firestopping ring and outer firestopping ring top, is the cone shape of downward protrusion, and interior firestopping ring is provided with exhaust hole, and outer firestopping ring communicates with chimney.Stove is arranged to this structure, and fully being heated of the pot that helps being heated on the stove enlarged heating surface area to greatest extent, improved energy transformation ratio.

Further, can said furnace wall and ajutage be arranged between 0 ° to 50 ° at the projected angle that horizontal plane forms, under the angle of this scope, the rotation wind between ajutage and the bullet can be bigger, more helps the abundant burning of faggot.

Further, filling with insulation material in the furnace wall, the more effective interior high temperature of body of heater that stops propagates into the outside, avoids damaging human body.

The utility model fuel source is abundant, and big or small faggot is inexhaustible with low cost, and the gasification cumulative is rapid, and sufficient combustion is practical reliable and stable, environmental protection and energy saving, and colleges and universities are convenient, light and handy, and easy mounting is safeguarded.

The specific embodiment

A kind of specific embodiment and accompanying drawing below in conjunction with the utility model are done further elaboration explanation to the utility model:

Half-gasification oven in the present embodiment comprises burning kitchen range and dore furnace; Said combustion furnace is by 2 forming at the bottom of stove 1 and the kitchen range; Said stove 1 is made up of kitchen range circle 12, interior firestopping ring 13 and outer firestopping ring 14, and its medium mess circle 12 is arranged on interior firestopping ring 13 and outer firestopping ring top, is the cone shape of downward protrusion; Interior firestopping ring 13 is provided with exhaust hole 15, and outer firestopping ring 14 communicates with chimney 16; Dore furnace is made up of furnace wall 3, boiler face 4 and furnace bottom 5; Filled heat-barrier material 31 in the middle of the furnace wall 3; Furnace wall 3 is provided with charging hole 6; At the bottom of the said kitchen range 2 and furnace bottom 5 between be provided with downward protrusion bullet 7 the dore furnace inner chamber is divided into upper cavity 8 and lower chamber 9, bullet 7 is provided with passage 71 and is communicated with upper cavities 8 and lower chambers 9, furnace wall 3 is provided with ajutage 10 and is communicated with lower chambers 9; The ajutage 10 outer air blasts 11 that connect, said furnace wall and ajutage are arranged on 40 ° at the projected angle that horizontal plane forms.Adopt the structure in the present embodiment, the half-gasification oven of this structure is when the continuous air blast of air blast gets into lower chamber; Because the setting of bullet can form one rotation wind between lower chamber, make the combustible substance in the upper cavity fully burn through the aperture on the bullet; Simultaneously because the bullet protrusion, can effectively be gathered incendiary material downwards, under the rotation wind action; Can promote temperature very soon, reach the purpose of vaporising fuel, significantly reduce in this dust that forms simultaneously and smog; And dust and the smog of the overwhelming majority will be through the chimney discharges, the infringement of human body are reduced to minimum, and the while can also effectively prevent the damage to human body of pernicious gas and high temperature.

But the utility model never only is limited in the above specific embodiment, and all are without prejudice to the equivalent variations of the utility model spirit or substitute, all will be within the utility model protection domain.
