Description

Automatically advance the energy-conservation air return stove of oxygen

Technical field:

The utility model relates to air return stove, particularly a kind ofly advances the energy-conservation air return stove of oxygen automatically.

Background technology:

Air return stove of the prior art is varied, but the ubiquity coal consumption is big, and it is insufficient to burn, the shortcoming that soot emissions is big.

Summary of the invention:

The purpose of this utility model is to provide a kind of energy-conservation air return stove of oxygen that advances automatically, utilizes the oxygen channel of this air return stove and combustion-supporting can make coal-fired fully burning, reaches the purpose of efficient energy-saving.

Formation of the present utility model: by interior external furnace body, boiler face, combustion chamber, heat-insulation layer, combustion-supporting, oxygen channel, tobacco bale, pipe, grate and base are formed, installation combustion chamber 15 on base 11, inner furnace body 13, external furnace body 14 and grate 10, installation boiler face 1 on external furnace body, between combustion chamber 15 and inner furnace body 13, be heat-insulation layer 17, oxygen channel 16 is installed on inner furnace body 13 between inner furnace body 13 and the external furnace body 14 and base 11, oxygen feeder 18 with oxygen channel 16 and burner hearth connection is arranged above inner furnace body 13, on the inner furnace body lid 2 toothed combustion-supporting 4 is being installed above the combustion chamber, tobacco bale 7 is installed in outlet flue 8 outsides above external furnace body 14, pipe 6 is installed above tobacco bale, and the below has except that cigarette ash door 9.

Combustion-supporting 4 is discs, in the centre of disk stove fire hole 20 is arranged, and below disk, even teeth 21 around the stove fire hole 20 has space 22 between tooth and the tooth.

Compared with the prior art; the utility model is equipped with oxygen channel outside inner furnace body; it is combustion-supporting that air enters combustion-supporting by oxygen channel and oxygen feeder; make burning more abundant; caloric value is higher; coal consumption is few; energy savings has heat-insulation layer between combustion chamber and the inner furnace body, it can make heat in the combustion chamber be not easy to around distribute; heat is more concentrated; the thermal efficiency is higher, and the tobacco bale that is communicated with outlet flue is arranged on external furnace body, and this tobacco bale can be discharged by pipe the cigarette ash post precipitation again by chimney; the pernicious gas of discharging is few, helps environmental protection.
