The utility model is by being provided with cold water circulation pump and condensing heat exchanger being set in flue, making needs the water of heating to form a circulation between body of heater and condensing heat exchanger, water in the stove is only as heat carrier, few consumption, thereby essentially no hardness does not have dissolved oxygen, so no fouling generation and oxygenless corrosion, but the service life of prolonged boiler body and operating efficiency; When simultaneously the cold water extracted out of cold water circulation pump is through condensing heat exchanger and the high-temperature flue gas heat exchange, return in the stove after the cold water heating, temperature is reduced to close dew temperature after the flue gas heat release, thereby the latent heat of condensation and obvious heat of smoke that the water recovery in the absorption flue gas discharges, reduced the heat loss of smoke evacuation, boiler thermal output can improve 5～10 percentage points; And absorption of N O effectively behind the smoke condensation
XAnd SO
XEtc. harmful component, purified flue gas, have the remarkable environmental effect; By the heat exchanger communicate with body of heater is set, can make the water after the heating form another circulation, high temperature furnace water carries out the partition heat exchange with external water in heat exchanger, and customer requirements is satisfied for user's use in outer water receiving heating back.The utility model compact conformation is reasonable, and is easy to use, and energy savings reduces use cost, is the existing fabulous substitute products of unpressurized hot water boiler, has remarkable economic efficiency and social benefit.
