The specific embodiment

The present invention is further described below in conjunction with accompanying drawing.

The reciprocal three return-stroke type structures that the utility model adopt in flue realize prolonging stroke, further improve the inner industrial and mineral of flue to introduce natural wind in the flue simultaneously.

Such as figure and shown in Figure 2, there is inner-tube structure body of heater 4 inside, form the sealing water jacket between this inner bag internal protecting wall 23 and body of heater 4 shells, body of heater 4 is horizontal type structure, body of heater 4 antethecas have slag bucket 2 and fire door 3, delivery port 6 is arranged at body of heater 4 tops, atmospheric exhaust mouth 8 and chimney 9, induced duct 10 and water return outlet 11 are arranged at body of heater 4 sidewalls bottom, the burner hearth 16 of body of heater 4 inside that are communicated with fire door 3 is communicated with forward flue, this flue is reciprocal rising return-stroke type structure, and flue is communicated with chimney 9 in body of heater 4 internal upper part rear ends, simultaneously, be horizontally disposed with induced duct 10 in this flue, blow in groove 13 of part ventilates on these induced duct 10 stage casing tube walls.

Base 1 is arranged at body of heater 4 bottoms, and in base 1 side shoot door 12 is arranged, these shoot door 12 interior connection flues.The dusts such as solid particulate matter that carry during flue gas process flue land, are pooled to the flue bottom to be removed from shoot door 12.

Thermometer 5 and hanger 7 are arranged at body of heater 4 tops.This thermometer 5 is near delivery port 6, and with the Measurement accuracy leaving water temperature, simultaneously, it is portable convenient by hanger 7 liftings to need at equipment.

Fire grate 15 is arranged at burner hearth 16 bottoms, and fire grate 15 belows are slag bucket 2.

Induced duct 10 horizontal cross are installed in burner hearth 16 rear portion fire grates 15 tops, simultaneously, induced duct 10 belows are sealedly connected with water bath box 14, water bath box 14 and water jacket UNICOM, the induced duct 10 upside outer walls groove 13 that blows in, along tangential induced duct 10 both sides that connect of sealing, wind groove 13 is to tilt incision, and this entry is positioned on water bath box 14 both sides along the top on water bath box 14 both sides.Wind groove 13 is the incision of tilting, so that the unlikely obstruction when descending of the flue dust in the flue, simultaneously, also appropriateness retardance flue gas releases through induced duct 10 from wind groove 13.

One group of horizontal water tube 17 is installed on bottom flue top at burner hearth 16 and induced duct 10 rear portions, and these horizontal water tube 17 two ends pick out internal protecting wall 23, are communicated with water jacket.

The front smoke box 18 of sealing is arranged at body of heater 4 internal furnaces 16 tops, there is back smoke-box 22 at the rear portion, the rear collection smoke box 21 that sealing is arranged above time smoke-box 22, the bottom flue is communicated with back smoke-box 22 above the rear portion, return smoke-box 22 and pass through next time smoke pipe 19 connection front smoke boxs 18, above smoke pipe 19 next time, collection smoke box 21 after front smoke box 18 is communicated with by rising smoke pipe 20.

The utility model is when installment work, owing to possess stack effect in the flue that hot flue gas forms, be to produce negative pressure in the flue, generate ascending air, at this moment the air from the external environment condition that introduce at induced duct 10 two ends is after entering body of heater 4, through water bath box 14 preheatings, and mix combustion-supporting with flue gas from wind groove 13 ejection Heat of Formation general mood curtains, simultaneously hot flue gas upwards is flowing in and carries out quick heat exchange when crossing horizontal water tube 17 in the place ahead from burner hearth 16, combustion position improves when crossing wind groove 13, then flue gas progressively finally effluxes from chimney 9 by three return flues of top, induced duct 10 air intakes were smooth and easy normal after empirical tests entered duty, and chimney 9 outer smoke evacuation cleanings and waste heat are lower.
