Abstract
The utility model discloses a secondary combustion furnace with oxygen supply by hot blast, which enables utilization rate and heat conversion rate of coal to be increased and smoke emission to be reduced. The secondary combustion furnace comprises a furnace body, the furnace body comprises a furnace pipe, an oxygen supply ring is arranged at an upper opening of the furnace pipe, the oxygen supply ring is in an annular structure with an inner cavity, oxygen supply holes are densely arranged on the inner side of the annular structure, one to six hot blast pipes penetrating through the bottom of the furnace body are tightly attached to the furnace pipe inside the furnace body, each hot blast pipe is in a tubular structure with an inner cavity, and the oxygen supply ring is hermetically connected with the hot blast pipes.
Description
Technical field
The utility model relates to combustion furnace, the stove and accessory that relates in particular to a kind of rural area warming, cooks and use.
Background technology
In the prior art, be the combustion stove of fuel with the coal, mainly be used for warming oneself, cooking in the rural area; Mainly be made up of body of heater, chassis, boiler face and ash bucket, coal is discharged mixed flue gas in body of heater flue internal combustion through chimney during use; Its shortcoming is, coal burning is insufficient, and the part fuel gas is discharged from chimney; Not only wasted the energy but also polluted environment, coal consumption is high, and the thermal efficiency is low.
The utility model content
The utility model technical problem to be solved provides a kind of hot blast oxygen supply after-burning stove, and it can improve the utilization rate and the thermal conversion rate of coal, reduces smoke discharge amount.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of hot blast oxygen supply after-burning stove, and it comprises body of heater; Body of heater comprises flue, and there is the oxygen supply circle at the fire door place on flue, and said oxygen supply circle has the loop configuration of cavity in being; This loop configuration inboard is uniformly distributed with the oxygen supply hole; Be provided with 1-6 root warm-air pipe at body of heater inner close fitting flue and penetrate bottom of furnace body, said warm-air pipe has the tubular structure of cavity in being, said oxygen supply circle is tightly connected with this warm-air pipe.
The beneficial effect of the utility model is, in body of heater, increased warm-air pipe, oxygen supply circle, formed secondary oxygen supply passage; Air gets into warm-air pipe by bottom of furnace body, because warm-air pipe is at body of heater inner close fitting flue, air is heated in warm-air pipe; And then get into the oxygen supply circle, and from the oxygen supply hole of oxygen supply circle inwall, spraying, hot-air fully contacts with coal burning flame, flue gas; The mixed flue gas that does not have completing combustion in the coal combustion process is carried out the oxygen supply second-time burning, reach abundant burning, make the interior temperature of stove improve 25% than conventional oven; Coal saving rate reaches 25%, and smoke discharge amount reduces 60%.

The specific embodiment
Like Fig. 1, shown in Figure 2, the utility model comprises body of heater 6, and body of heater 6 innermost layers are flue 8; There is oxygen supply circle 9 at the fire door place on flue 8, and this oxygen supply circle 9 has the loop configuration of cavity in being, this loop configuration inboard is uniformly distributed with several oxygen supply holes 10; Be provided with 1 warm-air pipe 11 at body of heater 6 inner close fitting flues 8 places and penetrate body of heater 6 bottoms, said warm-air pipe 11 has the tubular structure of cavity in being, said oxygen supply circle 9 is tightly connected with this warm-air pipe 11; Said two cavitys are interconnected, and body of heater 6 following air get into from warm-air pipe 11 bottoms, and the warm-air pipe 11 of flowing through gets into the oxygen supply circles; From oxygen supply hole 10, flow out at last, constitute complete secondary oxygen supply passage.
Air gets into warm-air pipe 11 below body of heater 6; Because warm-air pipe 11 is at body of heater 6 inner close fitting flues 8, air is heated in warm-air pipe 11, and then gets into oxygen supply circle 9; Ejection from the oxygen supply hole 10 of oxygen supply circle 9 inwalls; Hot-air fully contacts with coal burning flame, flue gas, and the mixed flue gas that does not have completing combustion in the coal combustion process is carried out the oxygen supply second-time burning, reaches clean-burning purpose.
Claims (1)
