Abstract
The utility model relates to a combined single furnace line with basin-shaped structure. The bottom of the basin is a barrier-shaped furnace line, and the wall and the center of the basin are respectively provided with a secondary air supplying port. The structure of the furnace line causes coal to be burnt in the basin-shaped structure of the furnace line, the combustion temperature is about 150 DEG higher than the combustion temperature in the prior art, the first and the second air supplies cause smoke gas to stay in a furnace chamber for a long time, mixed combustion is full, and the generation of the black smoke is fundamentally avoided. The utility model reserves the characteristic of easy operation of a single furnace line and overcomes the defect that an existing single furnace line can not eliminate smoke dust.
Description
The utility model relates to the single fire grate of a kind of fire coal, the combined type list fire grate that especially a kind of normal-pressure boiler uses.
Existing single fire grate boiler for domestic, fire grate is a grating structure, fire grate is air compartment down, be the combustion chamber on the fire grate, during burning, the wind of air compartment only from the gap of palisade fire grate to the combustion chamber air feed, flue gas can not get fully mixing and stirring in burner hearth, does not reach the condition that secondary flue gas burns again.So there is the drawback that can not thoroughly eliminate smoke in single fire grate boiler for domestic.
The purpose of this utility model is to disclose the combined type list fire grate of a kind of energy smoke abatement and dust control.
For finishing above-mentioned purpose, the technical scheme that is provided is as follows: combined type list fire grate is a kind of peviform structure, it at the bottom of the basin palisade list fire grate, the palisade gap can provide wind one time to burning, tub wall is outward-dipping, the tub wall top can with combustion chamber inwall sealing-in, secondary air hole is arranged on the tub wall, can provide secondary wind combustion-supporting to the combustion chamber by this wind hole.During burning, fire coal can be in this peviform fire grate internal combustion, directly do not contact the cold water layer,, at first reached clean-burning condition so ignition temperature is higher about 150 ℃ than general single fire grate, secondary air feed on the tub wall, the hot blast turbulent flow can be provided to the anoxic zone of burner hearth, and this hot blast turbulent flow provides comburant oxygen on the one hand in burner hearth, delayed the mass rate of emission of flue gas on the other hand, make fuel gas in burner hearth, have an opportunity fully to burn, reach the purpose of smoke abatement and dust control.
In the enforcement when if the peviform fire grate is big, also can secondary wind blender be set at the center of basin bottom gate shape fire grate, this secondary wind blender can be an inverted cup, and secondary air hole is arranged at the bottom of its glass and on the perisporium, can provide secondary wind to burner hearth by this wind hole, make the burning smoke better effects if.
This combined type list fire grate had both kept single fire grate advantage simple to operation, had overcome the halfway drawback of smoke elimination of the prior art again.Below in conjunction with the embodiment accompanying drawing this application is described in further detail.
Fig. 1 is the structural representation of the utility model in boiler for domestic.
Fig. 2 is the vertical view of the utility model embodiment.
As shown in the figure, combined type list fire grate is a peviform structure, 1 is the palisade fire grate at the bottom of the basin, tub wall 2 centers at the bottom of the basin, and is inclined upwardly the top of tub wall and inboard wall of burner hearth 6 sealing-ins, make the outer downside of tub wall that one space 7 be arranged, this space 7 communicates with an air compartment (or ash storage chamber) 8, and some secondary air holes 5 are arranged on the tub wall, and this wind hole is connected with tub wall space 7 outward.Centre bit at the bottom of the basin is equipped with secondary wind blender 3, this blender shape such as inverted cup, its rim of a cup inserts downwards in the palisade fire bars, or otherwise combine with fire bars at the bottom of the basin, at the bottom of its cup up, cup is at the end and on the perisporium some secondary air holes are arranged, and can provide secondary wind combustion-supporting to burner hearth by this wind hole.
During use, coal is in peviform fire grate internal combustion, and the coal that burnt quarrel and ash content can fall into from the gap of basin bottom gate shape fire grate in air compartment 8, so that eliminate.Provide wind by gap at the bottom of the basin 9 one time to fire box, provide through the space 7 and the secondary wind of space 10 preheatings to burner hearth, make coal fully burning in fire grate, reach the purpose of smoke abatement and dust control by tub wall wind hole 5, secondary wind blender wind hole 4.
The single fire grate of this peviform can be circular, can also be square, at the bottom of the basin and tub wall can be sub-assembly, also can be single piece.During use, air feed can be a natural air exhaust, also can be by the system air blast of the air compartment Final 8.
Claims (3)
1, a kind of combined type list fire grate, it is characterized in that: described single fire grate is a peviform structure, it at the bottom of the basin palisade fire grate, its gap can provide wind one time to burning, the tub wall ring encloses at the bottom of the basin and is outward-dipping, the tub wall top can with combustion chamber inwall sealing-in, secondary air hole is arranged on the tub wall, can provide the secondary air feed to the combustion chamber by this wind hole.
2, the single fire grate of peviform as claimed in claim 1, it is characterized in that described basin at the bottom of the center one secondary wind blender is arranged, secondary wind air supply hole is arranged on this blender.
3, the single fire grate of peviform as claimed in claim 1 is characterized in that described secondary wind blender shape such as inverted cup, on the cup end and the perisporium wind hole is arranged.
