Abstract
The utility model discloses a horizontal coal gasification boiler which belongs to the technical field of boilers and solves the problems of deep hearth, small operating area, inconvenience for operation, combustion insufficiency and lower thermal efficiency of a high-power coal gasification boiler in the prior art. The horizontal coal gasification boiler comprises a positive combusting coal gas generating chamber and a negative combusting coal gas generating chamber which are mutually communicated at the upper parts and respectively provided with a coal feeding boiler door, wherein the negative combusting coal gas generating chamber is positioned between the positive combusting coal gas generating chamber and a heat absorbing region, and the coal feeding boiler doors are arranged at different side surfaces of the boiler. The utility model increases the combustion space and the area of a fire outlet to ensure that the combustion is more complete and the heat absorbing region is convenient for absorbing heat; and by adopting a mode of feeding coal from different side surfaces, the area of the hearth is increased, the combustion is more complete, the heat efficiency is improved, and the hearth becomes shallow so that a fireman is convenient for operation.
Description
Technical field
The utility model belongs to the technical field of boiler, is specifically related to a kind of horizontal coal-fired coal gasification boiler.
Background technology
Existing horizontal coal-fired coal gasification boiler comprises small-power hand-fired boiler and high-power boiler.High-power coal-fired coal gasification boiler, comprise preceding generation chamber and the left and right sides, the back reverse-burning gas generation chamber of just burning gas that top interconnects, before just burning gas generation chamber bottom be provided with and just burn fire grate, just burning fire grate below high-pressure blast and water-stop pond are being set, just burn the fire grate top and be the generating region that just burns gas, the generating region that just burning gas top is provided with bypass pipe, and bypass pipe is provided with by-passing valve and is connected with chimney; Reverse-burning gas generation chamber bottom, the back left and right sides is provided with anti-burn grate, and the anti-burn grate below is provided with the combustion chamber and has the crater that is communicated with the district of absorbing heat, and the anti-burn grate top is the reverse-burning gas generating region, and secondary high-pressure wind is established in reverse-burning gas generating region top.Because existing high-power coal-fired coal gasification boiler unreasonable structure, burner hearth is dark, and operations area is little, has inconvenient operation, and it is insufficient to burn, the problem that the thermal efficiency is low.
Summary of the invention
There is inconvenient operation in high-power coal-fired coal gasification boiler to the utility model in the prior art in order to solve, and it is insufficient to burn, and the problem that the thermal efficiency is low provides a kind of horizontal coal-fired coal gasification boiler.
The utility model adopts following technical scheme to realize:
Horizontal coal-fired coal gasification boiler, comprise the generation chamber that just burns gas, the reverse-burning gas generation chamber that adds coal stove door that be provided with that top interconnects, wherein the reverse-burning gas generation chamber is arranged at and just burns gas between generation chamber and the heat absorption district, adds the not ipsilateral that coal stove door is opened in boiler.
The operation principle of this utility model is when the coal adding is just burning gas generation chamber, the mixed gas and the used heat that produce under the wind action of a malleation high pressure enter the reverse-burning gas generation chamber by connector, under the effect of high wind of secondary malleation and air-introduced machine, the coal seam, Jiao's layer that penetrate the reverse-burning gas generating region enter the combustion chamber with anti-burn grate and fully burn, entering heat absorption district and fin type backhaul at last carries out after heat joins, enter chimney by desulfurizer, whole process reaches environmental protection, the energy-saving effect of smokeless and dust free.
The reverse-burning gas generation chamber comprises anti-left side gas generating chamber and anti-right side gas generating chamber.
The utility model compared with prior art has following beneficial effect:
(1) the reverse-burning gas generation chamber is arranged at and just burns gas between generation chamber and the heat absorption district, increases the area of combustion space and crater, makes burning more abundant, is convenient to the heat absorption of heat absorption district;
(2) adopt the not mode of ipsilateral coal, increase the burner hearth area, burning more from dividing, improves the thermal efficiency, and burner hearth is shoaled, and is convenient to fireman's operation.
