The counter-heating boiler in the utility model has the advantages of low-coast, sufficient-combustion, energy saving, smoke-free and environment protecting.

Description

The counter-burning type heating stove

Technical field: the utility model relates to a kind of heating stove, especially a kind of counter-burning type heating stove.

Background technology: at present, the small heater stove adopts positive sintering structure mostly, and this structure heating stove burning is insufficient, contaminated environment, use cost height.

Summary of the invention: in order to solve the problem of above-mentioned existence, the utility model provides a kind of cost low, the counter-burning type heating stove of sufficient combustion, energy-conservation, smokeless environment-friendly type.

Concrete technical scheme is as follows: a kind of counter-burning type heating stove, comprise body of heater, throw the coal shutter, the slagging-off air register, the combustion chamber, smoke tube mouth, flame retardant coating, water jacket, the body of heater top is provided with smoke tube mouth and delivery port, it between the shell on body of heater both sides and top and inwall water jacket, a side is provided with water return outlet therein, be provided with throwing coal shutter at the body of heater rear, with throw the coal shutter combustion chamber of ining succession, flame retardant coating and Heat Room inlet is arranged in the combustion chamber, iron plate and inwall form water jacket above the flame retardant coating of top, combustion chamber, the Heat Room inlet communicates with smoke tube mouth by Heat Room, is provided with the slagging-off air register in body of heater the place ahead.

Compare with prior art, the utility model adopts said structure, utilize the reverse burning method of moulded coal by the forward direction after-combustion, high-temperature gas absorbs heat through the Heat Room inlet by the heat exchanger fin in inwall and the Heat Room, and the water in the heating water jacket carries out heat supply, and this product can be banked up a fire more than 10 hours for a long time, the heating stove of this structure makes the moulded coal can sufficient combustion, reducing use cost, reach and economize on coal, smokelessly, is a kind of counter-burning type heating stove of environment-friendly type.

Description of drawings: the utility model is described in detail below in conjunction with accompanying drawing.
