Burner hearth bottom is provided with ash bucket, is provided with independent air inlet in base, in the cavity of air inlet, is provided with heat accumulating
.
Described burner hearth comprises gentleization of return air burner hearth burner hearth.
The gasification chamber of gasification hearth is communicated with outside atmosphere by gasification chamber air inlet and secondary air inlet, is provided with heat accumulating in secondary air inlet.
Between air inlet and secondary air inlet, by dividing plate, separate.
Bottom at base is provided with exhaust opening, and exhaust opening is connected with underground flue by underground flue mouth, and underground flue is connected with chimney.
The exhaust opening of base one side is connected with underground flue by underground flue mouth, and underground flue is connected with chimney.
In base, be also provided with and independently dry bavin case.
Described heat accumulating is porous ceramics piece, porous ceramic ball or fin.
A kind of underground flue warming stove that the utility model provides by adopting the mode using base as discharge flue, circulates high-temperature flue gas stream, so base distribute heat in base.Then combustion product gases is incorporated into the underground flue that is embedded in below ground again, thereby indoor chimney need not be set, attractive in appearance in holding chamber, and the ash bucket of setting can conveniently be discharged the ashes in burner hearth.The air inlet arranging is convenient to preheating burner hearth air intake, and the heat accumulating in it can further improve air preheat effect, thereby saves energy consumption, and the exhaust opening of setting and underground flue mouth are convenient to socket installation very much.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is air return stove structural representation of the present utility model.
Fig. 2 is gasification furnace structure schematic diagram of the present utility model.
Fig. 3 is the schematic diagram of optimizing structure of the present utility model.
In figure: desktop 1, body of heater 2, return air burner hearth 3, air return flues 4, charging aperture 5, enters mouth 6, base 7, ash bucket 8, exhaust opening 9, underground flue 10, underground flue mouth 11, chimney 12, gasification hearth 13, gasification chamber air inlet 14, air inlet 15, heat accumulating 16, dividing plate 17, secondary air inlet 18, dries bavin case 19, burner hearth 20.
The specific embodiment
In Fig. 1,2, a kind of underground flue warming stove, comprises warming stove, in body of heater 2, is provided with burner hearth, and charging aperture 5 is communicated with burner hearth 20 through body of heater 2, and the upper end of body of heater 2 is provided with the fire-sealing ring for closed furnace body 2 upper ends, in the upper end of body of heater 2, desktop 1 is installed;
Between burner hearth and body of heater 2, be provided with air return flues 4, body of heater 2 bottoms are provided with the base 15 with sealed cavity, and air return flues 4 is communicated with base 15 by entering mouth 6, and base 15 1 sides or bottom are provided with exhaust opening 9;
Burner hearth 20 bottoms are provided with ash bucket 8, are provided with independent air inlet 15 in base 7, are provided with heat accumulating 16 in the cavity of air inlet 15.Air inlet own can be by the air preheat entering, but the effect of this preheating is bad, and by the interior heat accumulating 16 that arranges of air inlet 15, for example porous ceramics piece, porous ceramic ball or fin, improved pre-heat effect, and then reduced energy consumption.After tested, after having increased preheating structure, the time that can accelerate to heat up water, same boiled 3 premium on currency in the situation that other conditions are identical, have increased the warming stove of preheating structure, have reduced by the heat time of approximately 1 minute.
Preferred as in Fig. 1,2, described burner hearth 20 comprises return air burner hearth 3 and gasification hearth 13.Wherein gasification hearth 13 refers to the burner hearth with gasification chamber, can on the top of burner hearth, carry out the burner hearth of secondary air tonifying Qi, so that flue gas fully burns.
Preferred as in Fig. 2, the gasification chamber of gasification hearth 13 is communicated with outside atmosphere by gasification chamber air inlet 14 and secondary air inlet 18, is provided with heat accumulating 16 in secondary air inlet 18.Structure thus, except by the preheating of burner hearth air intake, also by secondary air also preheating.
Preferred as in Fig. 2, between air inlet 15 and secondary air inlet 18, by dividing plate 17, separate.Because the air quantity of air intake and secondary air is different, it is useful therefore the two being kept apart.
