Description

The energy-conserving and environment-protective gas furnace

The utility model relates to a kind of energy-conserving and environment-protective gas furnace, belongs to civilian normal pressure heating equipment.

Central heating has covered the warming of northern big and medium-sized cities gradually, yet, some problems of central heating also come out inevitably, and long neglected and in disrepair, pipeline leakage, overload operation cause that temperature is not enough, the heat expense is higher, more there is the junction, town and country to adopt coal heating away from the resident of heating system more, not only poor efficiency but also pollution are unfavorable for energy-conserving and environment-protective, have occurred some imports or homemade gas heating stove on this basis, but price is too high, and the low-income household is difficult to accept.

The utility model provides a kind of energy-conserving and environment-protective gas furnace at the problems referred to above, and it can guarantee, and gas furnace is efficient, the energy-saving and environmental protection characteristics, can overcome the drawback that it costs an arm and a leg again, is easy to apply in users.

Task of the present utility model is finished as follows: vane type is crossed the water box with inner bag, outer courage bottom is communicated with, other has inside and outside courage to be communicated with the water box inside and outside courage top is communicated with, outer courage inwall is corrugated, fixing spiral heat transfer baffle plate on the inner bladder outer wall, flue by center cavity bottom by curve outside the body of heater of inside and outside courage top lead to outdoor, the place of curving is provided with ventilating fan, flue upper and lower side sidewall is provided with honeycomb hole, the clearance spaces that this flue outer wall and center cavity are formed is a smoke collecting chamber, outer courage upper and lower side is provided with delivery port, water return outlet is located in above-mentioned overall structure on the combustion gas stone or metal plate for standing a stove on as a precaution against fire.

The utility model adopts vertical pair of courage not have pipe normal pressure structure, the bottom impeller formula crosses the water box and outer courage inwall adopts corrugated, inner bladder outer wall is spiral heat transfer baffle plate fixedly, increased heating surface area effectively, in to the bottom of furnace body heating, the flame thermal current is crossed the oblique empty gap of water box from vane type and is passed through, under the buffer action of spiral heat transfer baffle plate, thermal current is in the corrugated surface convergent-divergent, the complications diffusion of climbing, carry out heat exchange with inside and outside courage, then, flue gas enters the ventilating fan of passing through on the flue return by lower end and lower end honeycomb hole and discharges by force by being advanced into smoke collecting chamber under the return of upper end, flows out delivery port after the WATER AS FLOW MEDIUM heat cycles in the inside and outside courage, cool after water return outlet flows back to body of heater, realize the work of circulation heating.

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
