Abstract

The utility model discloses a soot reburning boiler which belongs to technological field of boiler and comprises a boiler body, a hearth in the boiler body, a chimney on top of the boiler body, a fuel inlet on bottom of the boiler body and an air inlet. Characteristically, a U shape flue is arranged in the hearth and divided into a soot outgoing passage and a soot returning passage. The soot outgoing passage is communicated with the chimney on top of the boiler body. Opened end of the soot returning passage is arranged on upper part of the hearth. Bottom of the soot returning passage is provided with a fire hole which is arranged on bottom of the hearth and communicated with fuel feeding port. An air inlet is arranged in bottom of the U shape flue and communicated with a ventilation pipe. The utility model has the advantage of novel design and simply structure. Through secondary combustion of the soot, the utility model saves energy, reduces environmental pollution and solves such technological problems as energy waster and environmental pollution.

Description

A kind of flue dust second-time burning boiler
Technical field the utility model belongs to the boiler technology field, is specifically related to a kind of flue dust second-time burning boiler.
The boiler of background technology prior art, it comprises body of heater, is provided with burner hearth in the body of heater, and the body of heater top is provided with chimney, and the body of heater bottom is provided with fuel and adds mouth and air inlet.The boiler of this structure, fuel are after the burner hearth internal combustion, and flue dust is directly emerged from the chimney at body of heater top, owing to contain the particle that does not have completing combustion in a large number in the flue dust, cause the waste of the energy and the pollution of environment.
The summary of the invention the purpose of this utility model provides a kind of flue dust second-time burning boiler, to solve technical problems such as energy waste that prior art can exist and environmental pollution.
The utility model flue dust second-time burning boiler is to improve realization on the basis of existing technology, and it comprises body of heater, is provided with burner hearth in the body of heater, and the body of heater top is provided with chimney, and the body of heater bottom is provided with fuel and adds mouth and air inlet; Its main points are to be provided with U type flue in the burner hearth, one of two flue of U type flue are smoke outlet flues, another is an air-returen flue, smoke outlet flue is communicated with the chimney at body of heater top, the openend of air-returen flue is positioned at the top of stove hall, the lower end of air-returen flue is provided with into burner, advances on the bottom surface that burner is positioned at burner hearth to add with fuel mouthful to be communicated with, and air inlet interior ventilation duct bottom being arranged on U type flue is communicated with.
Operation principle of the present utility model is: the flue dust that produces after the fuel combustion rises to upper furnace, openend by air-returen flue enters U type flue, under the acting in conjunction of the ventilation duct in the firepower of burner and U type flue bottom are entered in the air-returen flue lower end, do not burn completely that flue dust burns once more, the flue gas that burns is completely discharged through chimney by the smoke outlet flue of U type flue.
The utility model modern design, design simply by the flue dust second-time burning, have promptly been saved the energy, have reduced the pollution of environment again, have solved the waste of the energy and the technical problems such as pollution of environment.
Appended drawings is the utility model structural representation.
The specific embodiment: with reference to the accompanying drawings, it comprises body of heater 1 the utility model, is provided with burner hearth in the body of heater 1, and body of heater 1 top is provided with chimney 2, and body of heater 1 bottom is provided with fuel and adds mouth 5 and air inlet 6; Be provided with U type flue 7 in the burner hearth, one of two flue of U type flue 7 are smoke outlet flues, another is an air-returen flue, smoke outlet flue is communicated with the chimney 2 at body of heater top, the openend 3 of air-returen flue is positioned at the top of stove hall, the lower end of air-returen flue 7 is provided with into burner 4, advances on the bottom surface that burner 4 is positioned at burner hearth to add mouthfuls 5 with fuel and be communicated with, and air inlet 6 is communicated with ventilation duct in being arranged on U type flue 7 bottoms.
