Description

Horizontal extreme misery pipe less boiler

Technical field

The utility model belongs to the improvement of horizontal single drum-type boiler structure, particularly horizontal extreme misery pipe less boiler.

Background technology

The flue gas flow of existing horizontal boiler all is more than three backhauls, and the fume emission resistance is big, need be used the bigger air-introduced machine of power when work the flue gas in the combustion chamber is outwards taken out, so that make the flue gas recirculation smoothness, is beneficial to the burning of coal.Though can increase the flow velocity of flue gas in the body of heater like this, but a large amount of heat energy, fine dusts in the combustion chamber of furnace body and do not have the black wood charcoal grain of completing combustion also to be extracted into body of heater to enter in the air outward thereupon, not only cause atmosphere pollution, but also reduced the heat energy utilization rate of boiler.For dedusting, need huge deduster be set at boiler tail, and this has increased the resistance of flow of flue gas in the body of heater.The method of servicing units such as air-introduced machine, deduster is installed in this employing additional, not only can not effectively address the above problem, but also has increased operating cost, cost of investment and the maintenance cost of boiler greatly.

Summary of the invention

The purpose of this utility model is to provide a kind of horizontal extreme misery pipe less boiler, not only the fume emission resistance is little, and need not to join in addition servicing units such as deduster, air-introduced machine and just can realize smokeless emission, can greatly reduce operating cost, cost of investment and the maintenance cost of boiler, improve the heat energy utilization rate.

The purpose of this utility model is achieved in that a kind of horizontal extreme misery pipe less boiler, smokeless chain fire-gate body of heater is housed bottom comprising, in the body of heater of traveling-grate stoker top is the combustion chamber, the top of body of heater is vertical drum that is being provided with, form the smoke-box that advances of sealing between the front bulkhead of the front bulkhead of body of heater, the face arch of combustion chamber and drum, the aft bulkhead of drum is being provided with smoke-box outward, be in the drum level uniform smoke pipe, the two ends of smoke pipe are connected respectively with into and out of smoke-box; Be in the face arch of combustion chamber the lateral separation uniform be provided with before arch tube, preceding arch tube forms flue each other, before arch tube the lower end respectively with the horizontal cross current that is positioned at combustion chamber face arch bottom, its upper end is connected with the bottom barrel of drum respectively, the uniform respectively water screen tube that is longitudinally-spaced that connecting on the two side of drum, the lower end of water screen tube respectively with the vertical cross current that is positioned at lower end, body of heater two side.

When the utility model uses, the coal that is transported in the combustion chamber by smokeless traveling-grate stoker can all obtain sufficient air-breathing when burning, coal is fully burnt, thereby reduce soot emissions effectively, the flue gas that contains a large amount of heat energy that coal burning in the combustion chamber produces enters in the smoke-box by the smoke outlet flue between the preceding arch tube, discharge through going out smoke-box by the smoke pipe that is positioned at drum by advancing smoke-box again, flue gas flow of the present utility model like this has only two backhauls, make the fume emission resistance reduce greatly, need not to join in addition deduster, servicing units such as air-introduced machine just can be realized smokeless emission, can greatly reduce the operating cost of boiler, cost of investment and maintenance cost.In addition, by not only having enlarged the heat-absorbent surface of water, and can also greatly improve the heat absorption speed of water in the drum the smoke pipe of flue gas in drum, improve the heat energy utilization rate.
