Abstract

The utility model designs a smoke-relieving coal-saving furnace device with low cost and stable combustion temperature, and coal has sufficient combustion to eliminate black smoke. The utility model comprises a combustion chamber and a stove plate, which is characterized in that a fire pulling port 8 is arranged at the horizontal direction of a coal bucket 1 and is arranged above a coal digging plate 2, a space between a coal controlling plate 2 and a wind separation plate 3 forms a bell mouth shape. The bottom of the wind separation plate 3 is arranged on a step guard board 9, a turnover fire wall 4 is installed at both side stove walls, the turnover fire wall 4 which is positioned in a hearth is composed of one to two blocks, and a turnover fire port 6 is arranged between the turnover fire wall 4 and a stove body top plate.

Description

The coal-saving furnace apparatus

The utility model belongs to the Industrial Stoves class, specifically a kind of coal-saving furnace apparatus.

The crowd knows known, and the coal-fired smoke contamination that produces is a global difficult problem always.Advanced machine burning grate firing has all been adopted as boiler etc. in the home and abroad on large-scale coal combustion equipment, thus only there is the smelting reason of dust, and all there is advanced cleaner the improvement home and abroad of dust, all can reach environmental protection standard basically.And in black smoke (the being lingemann blackness) improvement as generations such as Industrial Stoves on the small-sized manual stoking combustion apparatus, the home and abroad does not all have good measure.The country that has changes equipment into gas, wet goods in order to eliminate black smoke.And China is a coal big country, can not adopt ways such as burning gas, oil firing fully, and not too tally with the national condition, so the technique for smoke of small investment, instant effect has just become the research direction of China and developing country.In technique for smoke, " double-layer inverse burning " arranged on the boiler, " naked light is counter to be burnt ", technology such as " lower feedings ", effect is fine, but these technology have certain limitation, such as " double-layer inverse burning " technology, fire bars is under the hot conditions all the time, so can only do fire bars with water cooling tube, both steam can be produced, can guarantee that again fire bars is not burnt ring, but ceramic kiln etc. water bar can not be used, one of its reason is a safety problem, because produce steam pressure is just arranged, former two is that temperature also can not be burnt to such an extent that get on therefore, takes away a large amount of heat energy because water bar will absorb, can not satisfy production requirement, and the employing silicon nitride ceramics, the aluminium oxide ceramics of purity 99% is used on the ceramic kiln, and then material cost is too expensive, unrealistic.

The purpose of this utility model is that it is low to have designed a kind of cost at the problem of above-mentioned prior art existence, and ignition temperature is stable, and coal can fully burn and reach the coal-saving furnace apparatus of eliminating black smoke.

The purpose of this utility model can reach by following measure:

A kind of coal-saving furnace apparatus, comprise combustion chamber, stove plate, it is characterized in that drawing crater 8 is located at the top of coal bunker 1 horizontal direction and coal mining board 2, be bell mouth shape between coal control board 2 and the wind isolation board 3, wind isolation board 3 bottoms are arranged on the ladder stove plate 9, turn over wall with flues 4 and are installed on the furnace wall of both sides, are positioned at burner hearth, constitute by one to two, turn over to be provided with between wall with flues 4 and the body of heater top board and turn over burner 6.

The purpose of this utility model can also reach by following measure:

Coal control board 2 is installed on the furnace wall of both sides;

On coal control board 2 and the wind isolation board 3 coal bunker 1 is housed;

Wind isolation board 3 bottoms are arranged on several from top to bottom second block of ladder stove plate 9;

Ladder stove plate 9 is inserted on the furnace wall of both sides, and it is arranged above and below is 40 °～45 °.

Advantage of the present utility model:

It is low to the utlity model has cost, ignition temperature is stable, coal is fully burnt, reach the advantage of eliminating black smoke, wherein economize on coal and ignition temperature stable be because of to the greatest extent with the black smoke burning, make it to change into heat energy, the corresponding raw coal imperfect combustion that reduced, there is not the variations in temperature of big rise and big fall, thus the suitable benefit of economizing on coal is arranged, again because after the coal of precombustion chamber becomes red-hot charcoal, draw the poker effect to fall into hot room through drawing crater, on the occasion of firepower vigorous in, add the carbon black that slowly continues and burn continuously, so temperature is very stable.

Fig. 1 is the utility model structural representation.

Below in conjunction with accompanying drawing the utility model is further described:

Raw coal is added by coal bunker 1, by control panel 2 control coal seam thicknesses, enter bottom by wind isolation board 3 control cold wind, make coal form anti-burning state, by the heat radiation of turning over wall with flues 4 control high temperature combustors 7, make the coal seam in precombustion chamber 5, slowly separate out fugitive constituents such as carbon black, carbon black enters after-flame in the high temperature combustors 7 by turning over burner 6, put in the drawing crater 8 and draw poker that the main fuel charcoals in the precombustion chamber 5 are drawn to drop down onto main combustion in the high temperature combustors 7, the lime-ash of after-flame drops on the open hearth bar 10 through 40 °～45 ° order of a permutation ladder stove plates 9, from the space decline ash charge pit 11 of open hearth bar 10.Behind the actual use coal-saving furnace apparatus, the discharging lingemann blackness of kiln is reduced to 1 grade by 5 grades, and the discharging blackness of glazed tiles pushed bat kiln, ceramic roller kiln is reduced to 0 grade by 3 grades.
