Abstract

The utility model relates to a smoke-eliminating energy-saving blowing stove implement burning coal, which is an ideal stove for cooking and heating. The utility model can be widely used for the reforming of a cooking range of restaurants, group dining rooms and residential families. The stove wall is used for forming a wind chamber. The inside and the outside of the burning chamber are provided with two exhaustion holes respectively. In particular to the two exhaustion holes on the upper part are provided with a reasonable angle, which can cause the burning flame and the outer source wind to interweave and then rise helically. Thus the coal can be burnt sufficiently and the goals of coal saving, smoke eliminating and dust removal can be achieved.

Description

Blowing stove implement burning coal

The utility model relates to the coal stove that a kind of external source is given wind, is particularly suitable for collectiveity canteen and catering and serving trade and civilian family and burns the usefulness of cooking a meal.

Along with updating of coal stove, many people design secondary or give the wind structure three times on to wind in the external source of stove and accessory combustion chamber, make fire coal not only when coal combustion, be subjected to helping oxygen to wind from the external source of furnace bottom and burner hearth sidewall, and help oxygen to wind once more on top, coal seam, make further burning such as carbon monoxide in the flame and hydrocarbon volatile matter, but that this stove and accessory still exists burning is not enough fully inadequately.

Task of the present utility model is further to change secondary to give the wind mode, impels secondary wind and burned flame really to form the wind fire and interweaves, and makes abundant after-flames such as carbon monoxide in the flame and hydrocarbon, thus reach economize on coal, the purpose of smoke elimination, dedusting.

The utility model both can be designed to independently stove and accessory, also can be supporting for pot and stove, its basic structure is that body of heater adopts double-decker, inwall surrounds the combustion chamber, form the ring-type air compartment between inwall and the outer wall, external source forms tangent line UNICOM by outer wall and air compartment for the ajutage of wind, and the bottom, combustion chamber seals with furnace bottom, characteristics are that the bottom and the top of inboard wall of furnace body is respectively equipped with a double wind hole and double secondary air hole, and wherein double secondary air hole has at least a row to be the elevation angle upwards in the combustion chamber.The elevation angle of double secondary air hole can be different, wherein descend the elevation angle of the elevation angle of vent greater than last vent, on this basis, double secondary air hole can make a vent and inboard wall of furnace body inner surface side angle less than 90 ° at least, and side angle direction should be consistent with the tangential direction of ajutage.The double angle of wind hole in the combustion chamber can be done following design: go up vent at the indoor angle of depression that is of fire coal, following vent is the elevation angle, the center extended line of two vents is intersected in the combustion chamber converge.Prominent formula frustum structure in above-mentioned all wind holes all can be designed to.

For ease of continuous coal in stove, the upper of furnace body side can be established fire door in addition, is provided with anti-reverse cigarette on the furnace body wall at fire door place, anti-reverse windburn hole.

Closed furnace bottom can be designed to two sections plank frames, and wherein one section is closure plate, and one section is the grate plate, and the effect of grate plate is to remove cinder and furnace bottom funnel draught.

The utility model furnace body outer wall adopts steel or cast iron to make, inboard wall of furnace body cylinder iron or the refractory material of refractory cement or sintering make.

The utility model ajutage forced ventilation, top, coal seam is by the air-supply of secondary air hole different angles in the combustion chamber, it is synthetic to impel wind and flame formation spiral upwards to interweave, and has improved flame intensity, and carbon monoxide and hydrocarbon volatile matter that burning is discharged are able to abundant burning.A double wind hole forms to intersect in the coal seam and blows, and the fluffing action by interior prominent formula frustum structure wind hole makes more easy firing of fire coal.

The utlity model has simple in structurely, cheap, advantage of convenient mounting is compared with traditional stove and accessory, and this stove and accessory can burn low colm, and economizes on coal and can reach more than 50%.

Fig. 1 is that the utility model is faced and partly cutd open structural representation

Fig. 2 is the utility model plan structure schematic diagram

Fig. 3 is that the utility model is used for the scheme of installation on the pot and stove

It is as follows to describe the utility model embodiment in conjunction with Fig. 1 and Fig. 2:

Main ajutage (11) is by furnace body outer wall (6) and air compartment (12) tangent line UNICOM, double secondary air hole (2,3) wind hole exits direction in combustion chamber (13) is the different elevation angle that makes progress, wherein descend the elevation angle of the elevation angle of vent (3) greater than last vent (2), last vent (2) outlet and inboard wall of furnace body (1) inner surface side angle are less than 90 °, and its direction is consistent with the tangential direction of main ajutage (11).A double wind hole (4,5) is to intersect air-supply up and down in the combustion chamber; Drop-bottom is divided into sealing plate (8) and grate plate (14), can go up pull at slideway (7) by handle (9).The upper of furnace body side is provided with fire door, and the furnace body wall at fire door place is provided with the wind hole (15) of the anti-contrary cigarette of burning with anger.

Claims

1, a kind of coal-fired wind fire furnace tool, inboard wall of furnace body surrounds the combustion chamber, inwall and outer wall form the ring-type air compartment, ajutage is by outer wall and air compartment tangent line UNICOM, the bottom, combustion chamber seals with furnace bottom, feature of the present utility model is that the bottom and the top of inboard wall of furnace body is respectively equipped with a double double secondary air hole in wind hole, and wherein double secondary air hole has at least a row to be the elevation angle upwards in the combustion chamber.
