Description

Bituminous coal burner for range

The application relates to a kind of burner class, and especially a kind of a kind of bituminous coal that is embedded in the stove body looses and burns burner.

The diffusing problem of burning the burner existence of existing bituminous coal mainly is that smoke abatement and dust control is bad, and its reason is that air feed is unreasonable, and bituminous coal combustion is insufficient, and the fugitive constituent that it is flammable fails fully to burn.

The application's purpose is to disclose a kind of kitchen range that can make the abundant smokeless combustion of bituminous coal and looses with bituminous coal and burn burner.

Technical scheme is as follows: the diffusing burner that burns of bituminous coal is made up of preheating air compartment and comb shape fire grate.The preheating air compartment is a semi-enclosed horse-hof shape, and comb shape fire grate is enclosed in wherein, is communicated with the air blast air inlet on the outer wall of this air compartment, on the air compartment inwall of the both sides up and down of fire grate some vents is arranged respectively.During use, this burner is embedded in the cooking stove, make the openend forward fire door of horse-hof shape air compartment, so that from fire door to the fire grate upper coal feeding, it on the fire grate combustion chamber, the fire grate lower end is communicated with ash hole, the air inlet of burner preheating air compartment is connected air blast, light the back with igniting and add coal combustion to fire grate from fire door, because the preheating air compartment is positioned at the high-temperature region of cooking stove, blast the interior air of air compartment earlier after preheating, discharged by the vent on the madial wall, the exhaust vent that is positioned under the fire grate is a wind hole again, and this wind aperture fire grate gap provides a wind combustion-supporting to the combustion chamber, the exhaust vent that is positioned on the fire grate is a secondary air hole, and this wind hole directly provides secondary wind combustion-supporting to the combustion chamber.Because this primary and secondary air is hot blast, mixes supply up and down from fire grate respectively again, make bituminous coal under the condition of high temperature polyoxy, fully to burn, its volatile coal smoke also burns totally down the combustion-supporting of secondary wind, thereby reaches bituminous coal smokeless combustion purpose.

In the enforcement, for the ease of fixed grate, be provided with a horizontal ledge in the front end inboard of horse-hof shape air compartment, the openend of horse-hof shape air compartment has a cross struts, and the two ends of fire grate are supported on respectively on this boss and the strut.The last leeward hole of air compartment inboard all is inclined upwardly.

Below in conjunction with the embodiment accompanying drawing this application is described in further detail.

Fig. 1 is the plane structure chart of this kitchen range with the diffusing burning of bituminous coal burner.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the end view drawing of looking up of Fig. 1.

Fig. 4 is that this burner combines the installation cut-away view with stove.

As shown in the figure, kitchen range is made up of horse-hof shape air compartment 5 and comb shape fire grate 4 with the diffusing burner 2 that burns of bituminous coal, in the front end inboard of horse-hof shape air compartment one horizontal ledge 3 is arranged, there is a cross struts 6 the corresponding opening end, the two ends of comb shape fire grate 4 are supported on respectively on this horizontal ledge 3 and the cross struts 6, on the front end outer wall of horse-hof shape air compartment, be provided with forced air inlet mouth 1, can aweather indoor forced-air blast by this air inlet.On fire grate air compartment madial wall up and down some vents are arranged respectively, wherein the wind hole 8 of fire grate below is a wind hole, and the wind hole 7 of fire grate top is a secondary air hole.During use, this burner combines as Fig. 4 with stove, burner 2 is embedded in the stove 9, the openend of burner is connected with the kitchen range door 10 of stove, so that in burner coal, other end air inlet 1 stretches out outside the stove, and the comb shape fire grate top of burner is combustion chamber 12, and the bottom leads to ash hole 11.

This kitchen range loose to burn burner with bituminous coal, is applicable to that dining room, restaurant, food stalls and collective's cooking stove use, and has that firepower is prosperous, a bituminous coal smokeless combustion, free of contamination advantage.

Claims (3)

1, the diffusing burner that burns of a kind of bituminous coal contains preheating air compartment and comb shape fire grate, it is characterized in that the preheating air compartment is a semi-enclosed horse-hof shape, and comb shape fire grate is enclosed in wherein, be communicated with air inlet on the outer wall of this air compartment, on the air compartment inwall of the both sides up and down of fire grate, some vents are arranged respectively.

2, bituminous coal as claimed in claim 1 looses and burns burner, it is characterized in that being fixed with a horizontal ledge on the front end madial wall of horse-hof shape air compartment, and the openend of horse-hof shape air compartment has a cross struts.

3, bituminous coal as claimed in claim 1 or 2 looses and burns burner, it is characterized in that the direction of the inboard vent of described air compartment is tilted to.
