Abstract
The utility model relates to a horizontal backfire coal burning boiler with a double-layer water pipe grate. The boiler body is horizontal. The horizontal backfire coal burning boiler comprises a coal storage bin, a coal gas generating chamber, a burning chamber and a reburning chamber and adopts a backfire burning type. The horizontal backfire coal burning boiler is characterized in that the bottom of the coal storage bin is provided with an upper water pipe grate; the bottom of the burning chamber is provided with a lower water pipe grate; the upper water pipe grate and the lower water pipe grate are arranged up and down; and both the upper water pipe grate and the lower water pipe grate are water cooling pipes. The top of the burning chamber is provided with a plurality of water jacket clapboards which separate the burning chamber away; and the gas path is trend to double-S. The reburning chamber is internally provided with a plurality of convection tubes. Compared with the prior art, the horizontal backfire coal burning boiler has the benefits as follows: the backfire burning type is adopted, the applicable scope of fuel is broad, the utilization rate of the fuel is high and the effect is remarkable in the aspects of reducing fuel consumption, lowering burning gross and relieving pollution of waste gas to environment; the service life of a water cooling grate is long; and the horizontal backfire coal burning boiler is convenient for users to use and achieves the double purposes of environment protection and energy saving.
Description
Technical field
The utility model relates to field of boilers, relates in particular to a kind of horizontal double-deck water pipe furnace grate backfire coal-burning boiler.
Background technology
Existing coal-burning boiler generally all is to be positive firing method, and promptly fuel is after burning on the fire grate, and in burner hearth, hot flue gas is discharged through chimney through furnace outlet and convection bank from bottom to top then.This positive combustion method produces a large amount of black smokes when burning, not only fuel availability is low, and contaminated environment.The solid fire grate non-refractory of cast iron, service life is short, changes inconvenience.
Summary of the invention
The purpose of the utility model provides a kind of horizontal double-deck water pipe furnace grate backfire coal-burning boiler, overcomes the deficiency of prior art, improves fuel availability, prolongs fire grate service life.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Horizontal double-deck water pipe furnace grate backfire coal-burning boiler, boiler furnace is horizontal, comprises coal store, gas generating chamber, combustion chamber and burning chamber; Adopt the backfire combustion system; It is characterized in that the coal store bottom is provided with the upper hose fire grate, the bottom, combustion chamber is provided with the downcomer fire grate; Upper hose fire grate and downcomer fire grate arrange that up and down said upper hose fire grate and downcomer fire grate all are water cooling tubes.
Said top of combustion chamber is provided with several water jacket partitions the combustion chamber is separated, and the combustion gas path becomes two S type trends.
Be provided with a plurality of convection tubes in the said burning chamber.
Compared with prior art; The beneficial effect of the utility model is: backfire combustion system fuel is applied widely; Fuel availability is high, reduce fuel consumption, reduce the burning total amount, to alleviate waste gas remarkable to effect aspect the pollution of environment, the water-cooled grate long service life; Be user-friendly to, reach the two purposes of receiving of environmental protection and energy saving.
