Description
Technical field
The invention belongs to field of boilers, be specifically related to coal-burning boiler, especially a kind of coal-fired Full-auto gasification burning boiler.
Background technology
Existing normal-pressure fire coal hot-water boiler adopts coal to do raw material, and coal cinder is normally from bottom to top burning in burner hearth, therefore the burning of ubiquity coal cinder is insufficient, and the problem that cinder is many, the thermal efficiency is low; Also exist simultaneously the dust of discharging many, even discharging problem not up to standard.
Summary of the invention
The object of the present invention is to provide that a kind of thermal efficiency is high, cinder is few, dust is few, can realize cleaning the coal-fired Full-auto gasification burning boiler of discharging.
In order to realize the present invention, the technical scheme that the coal-fired Full-auto gasification burning boiler of the present invention is taked is as follows:
A kind of coal-fired Full-auto gasification burning boiler, it comprises combustion chamber, Heat Room, wind force device, chimney, cleaning door, wherein, described combustion chamber and described Heat Room closely are set together and the outside is provided with aluminum alloy frame; Described combustion chamber comprises burner hearth, ventilation terminal, wherein burner hearth top and following a ventilation terminal is set respectively; Described Heat Room vertically is provided with some smoke pipes, is provided with two cleaning doors below the smoke pipe; Described wind force device comprises blower fan, volume damper, wind-distributing pipe, wherein blower fan is connected with volume damper, volume damper is connected with two wind-distributing pipes, and wind-distributing pipe wherein is connected with the ventilation terminal above the burner hearth, and another root is connected with ventilation terminal below the burner hearth.
Above-mentioned coal-fired Full-auto gasification burning boiler, described chimney are vertically set in the Heat Room and with one of them cleaning door and are connected.
Above-mentioned coal-fired Full-auto gasification burning boiler, the air quantity of the ventilation terminal above the described burner hearth is regulated less than the ventilation terminal air quantity below the burner hearth by volume damper.
Above-mentioned coal-fired Full-auto gasification burning boiler, described burner hearth front is provided with coal feeding hole, loose cinder notch and gray-drawing port successively by the upper-lower position relation.
The coal-fired Full-auto gasification burning boiler of the present invention is to realize that like this coal cinder Full-auto gasification in combustion process burns:
The coal feeding hole of coal cinder before burner hearth put into and entered fire grate the burner hearth, burning downwards on upper fire-grating, open blower fan, the adjusting volume damper makes the air quantity of the ventilation terminal below the burner hearth greater than the air quantity of the ventilation terminal above the burner hearth, coal cinder is burning downwards on upper fire-grating, the coal cinder imperfect combustion of fire grate top, the coal gas that under anoxic, hot conditions, generates simultaneously, enter the fire grate middle and lower part under the wind-force effect of the ventilation terminal of coal gas on burner hearth, and fully burning under the excess oxygen of the generation of the ventilation terminal below burner hearth.Thermal-flame enters below fire grate the smoke pipe of Heat Room and the water heat exchange, and enters cleaning door and chimney is discharged after backhaul up and down.
Its positive meaning of the coal-fired Full-auto gasification burning boiler of the present invention is: adopt that malleation is instead burnt, the combustion technology of multiple spot air distribution, the top in burner hearth arranges air intake one time, the bottom secondary air is set and greater than air intake, strengthen the oxygen supply amount.After coal cinder drops into, the fuel gas coal gas that produces in burner hearth burnouts being lighted by the coal seam high temperature combustion zone fully, the coal gas that generates under anoxic, hot conditions is simultaneously lighted during downwards by fire grate, sufficient combustion, and the flame of centre temperature can reach more than 1000 ℃.Uprise according to the actual motion thermal efficiency of actual measurement boiler and to reach more than 80%, comprehensively economize on coal more than 30% than the traditional heating boiler, each is few more than 30% for cinder and dust.
