Abstract
The utility model belongs to the technological field of hot water boiler, and in particular relates to a coal-gasification hot water boiler. The coal-gasification hot water boiler solves the problem that the direct coal burning boiler in the prior art wastes the energy and pollutes the environment. And the coal-gasification hot water boiler comprises a gas generation chamber; a fire grate is arranged in the gas generation chamber; one side of the gas generation chamber is provided with a combustion chamber; the gas generation chamber is connected with the combustion chamber through a fire outlet; the combustion chamber comprises a front combustion zone and a back heat-absorbing zone with a water tube; the front combustion zone is arranged on the side near the fire outlet and is provided with a fire tube on the top; and the front combustion zone is communicated with the back heat-absorbing zone; the wall of the front combustion zone under the fire tube is provided with a closed dedusting furnace door; the wall of the gas generation chamber below the fire grate is provided with a positive-pressure fan. The coal-gasification hot water boiler has the beneficial effects of complete combustion of coal to save the energy and to protect the environment, structural integrity, simple operation, beautiful design, high thermal efficiency, reduction of heat loss, and achievement of standards for emissions.
Description
Technical field
The utility model belongs to the technical field of hot water boiler, is specifically related to a kind of gasification hot water boiler.
Background technology
The direct combustion coal burning boiler all is the coal direct combustion in the prior art, and coal generates burning smoke and directly do not enter atmosphere not through fully burning, has not only wasted energy but also contaminate environment.
Summary of the invention
The utility model had not only wasted energy but also problem of environment pollution caused in order to solve in the prior art direct combustion coal burning boiler, provide a kind of before the gasification hot water boiler of fire tube, back water pipe pressure combustion
The utility model adopts following technical scheme to realize: a kind of gasification hot water boiler, comprise gas generating chamber, fire grate is installed in the gas generating chamber, it is characterized in that gas generating chamber's one side is provided with the combustion chamber, gas generating chamber is connected by crater with the combustion chamber, the combustion chamber comprises back heat absorption district (the preceding fire tube that close crater one side and top are provided with the preceding combustion zone of fire tube and water pipe is set, back water pipe), preceding combustion zone and top, back heat absorption district interconnect, the preceding combustion zone wall of fire tube below is provided with sealing deashing fire door, on gas generating chamber's wall of fire grate below positive pressure fan is installed.
Heat absorption district, back is connected with spray equipment, and the spray equipment bottom is provided with reaction tank.Crater connects blowing mouth.Gas generating chamber establishes on top and dispels pipe.
The structure design of fire tube, back water pipe overcomes the deficiency of other hot water boiler before described in the utility model, coal adds gas generating chamber, gasification back and the coke generation mixed gas that burns jointly, under the effect of the positive power of blower fan, mixed gas enters in the internal fire pipe of preceding combustion zone by crater and fully burns, the cinder of fire tube below has also carried out sufficient burning simultaneously, enters the post-heating district then water pipe is heated back heat transfer, effect smokeless, dustless, no chimney that whole process reaches.
The utlity model has following beneficial effect:
1, the gasification of coal burning is combined with the cinder burning, carry out pressure combustion in gas generating chamber earlier, in fire tube, burn again, coal is fully burnt, thereby reach effect in energy saving and environmental protection.
2, structural integrity, simple to operate, handsome in appearance.
3, preceding fire tube thermo-efficiency height, back water pipe prevent that tar from stopping up, and make whole stove fully hot, reduce thermosteresis, reach discharging.
