Description

A kind of boiler

Technical field

The utility model relates to boiler, especially a kind of back firing boiler of doing fuel with coal.

Background technology

Prior art do the back firing boiler of fuel with coal, at furnace body inside water tank is arranged, lower inside has fire bars, constitute the anti-chamber of burning between heat pipe and fire bars, combuster on the heat pipe, constitute hybrid combustor between combustion chamber and body of heater top, constitute the supercharging bag between body of heater and furnace top cover, body of heater relative between furnace base and fire bars is provided with except that cinder notch, the anti-chamber of burning, the combustion chamber, be respectively equipped with fire door on the relative body of heater of hybrid combustor, coal filling hole, observation panel, under the body of heater, in, top is respectively equipped with water inlet, hot water outlet, the gas outlet, its weak point is that smoke discharge amount is big, and the thermal efficiency is low.

Summary of the invention

It is little that the purpose of this utility model provides a kind of smoke discharge amount, the boiler that the thermal efficiency is higher.

The purpose of this utility model can realize by following measure: at furnace body inside water tank is arranged, lower inside has fire bars, constitute the anti-chamber of burning between heat pipe and fire bars, combuster on the heat pipe, constitute hybrid combustor between combustion chamber and body of heater top, constitute the supercharging bag between body of heater and furnace top cover, body of heater relative between furnace base and fire bars is provided with except that cinder notch, the anti-chamber of burning, the combustion chamber, be respectively equipped with fire door on the relative body of heater of hybrid combustor, coal filling hole, observation panel, under the body of heater, in, top is respectively equipped with water inlet, hot water outlet, the gas outlet, connect body of heater and be positioned at the indoor steam jet of anti-burning and connect the steam pipe that is connected with furnace top cover, mixed combustion is indoor the picogram cage, has the upper end to connect the chimney of furnace top cover in the picogram cage.

The purpose of this utility model also can realize by following measure: picogram cage bottom is provided with the ash disposal pumping board.

The utility model enters the superheated steam of supercharging bag in the furnace top cover that to spray into anti-burning behind the steam jet indoor by steam pipe, moment cracking and burning in hot room, produce certain heat energy, in addition, after the flue dust that water vapour and body of heater internal combustion form contacts flue dust weight is increased the weight of and land, be one-time dedusting; In first combustion chamber, flame is entered behind the hybrid combustor top at the indoor eddy current that forms of mixed combustion by the flue that overdoes, and has prolonged the time of staying of flue gas in body of heater, has improved the thermal efficiency, and flue dust falls in the backspin process, is final dusting; After a small amount of flue gas after the eddy current dedusting rises once more, enter the picogram cage at hybrid combustor, and produce eddy current once more therein, flue dust is dropped on the ash disposal pumping board, be third dedusting.
