1. combustion gas " dual-volume storage+condensing heat-exchange system " heating, the bath hot water device, the type of furnace:

  • wall hanging stove, land stove, by wall hanging stove outer covering (1), combustion gas interface (2), normally closed solenoid valve (3), gas adjustment valve is turned round (4), burner (5), first combustion chamber (6), following volume heat exchanger (7), flame channel (8), heat-insulation layer (9), coil pipe (10), preheating water conduit (11), gas vent (12), second combustion chamber (13), combustion-supporting air inlet (14), last volume heat exchanger (15), chimney (16), shelves wind resistance absorber plate (17), automatic blow off valve valve air relief or outer tank (18), heating return pipe (19), water inlet pipe and water outlet pipe (20), (22), supply water temperature probe (21), add water and adjutage (23), water pump (24), heating delivery port (25), heating water return outlet (26), add water and dewatering outlet (27), intake-outlet (28), (29), return water temperature probe (30) microcomputer controller (31), flame-observing hole (32) is formed, it is characterized in that;

    combustion gas interface (2) is advanced combustion gas, microcomputer controller (30) is opened normally closed solenoid valve (3), gas adjustment valve is turned round (4) and is adjusted the gas quantity size according to heating and domestic water situation, burner (5) and first combustion chamber (6) burning, following volume heat exchanger (7) and flame channel (8) are heated, heat absorption, fireworks mix with the combustion air that combustion-supporting air inlet (14) enters to second combustion chamber (13) again, carry out the burning second time, little for preventing the fireworks resistance, energy waste, system is when resistance to heat absorber plate (17), after last volume heat exchanger (15) was heated again, flue gas entered atmosphere naturally from chimney (16);

    Totally reach and enter atmosphere after combustion gas is fully burnt, heating power makes full use of, fireworks fully burn naturally;

    Heating water return outlet (26), return pipe (19) are metal communicating pipes, the heating return water temperature is lower, fire, water temperature difference is big, heat absorption power is strong, so the heating backwater is got back to volume heat exchanger (15) heat absorption earlier, is the condensing water tank, arrive volume heat exchanger (7) heating down by preheating water conduit (11) again, water pump (24), heating delivery port (25) heating are arranged, return heating water return outlet (26) after the heating and carry out next circulation;

    Being shaped in the water cavity of following volume heat exchanger (7) can be for the heat exchanger coil (10) of bathing life with hot water, the shell of volume heat exchanger (7) is passed down at the two ends up and down of coil pipe (10), promptly be turnover pipe (20), (22) of coil pipe (10), coil pipe turnover pipe (20), (22) respectively connect metal tube, metal tube extends and passes the bottom of wall hanging stove outer covering (1), is intake-outlet (28), (29) of bathing domestic water;

    The top of last volume heat exchanger (15) is shaped on automatic blow off valve valve air relief or outside expansion tank (18), automatic blow off valve valve air relief or outside expansion tank (18) have been to put gas and auto-flushing in the volume heat exchanger automatically, and the gas in the following volume heat exchanger (7) is to overflow by the gas vent (12) on the preheating water conduit (11) to overflow to last volume heat exchanger (15);

    It has been to add water and maintenance discharges water that the heating burner adds water and dewatering outlet (23);

    Heat-insulation layer (9) has been the complete machine insulation, makes full use of heat energy;

    Supply water temperature probe (21) is the regulation and control supply water temperature and controls water temperature, return water temperature probe (30) is to watch the backwater water temperature, microcomputer controller (31) is gone up the long-term supply water temperature that shows, return water temperature probe (30) microcomputer controller (31) is controlled and can be shown return water temperature;

    Studding with microcomputer controller (31), gas adjustment valve on the wall hanging stove outer covering (1) turns round (4) and sees burner (32).
