A kind of novel condensing heating/hot water gas two-purpose stove
Technical field
The utility model relates to a kind of heating/hot water gas two-purpose stove, more particularly relates to a kind of condensing heating/hot water gas two-purpose stove.
Background technology
Traditional heating/hot water gas two-purpose stove is to utilize heat exchanger to absorb the heat that fuel gas buring produced, pass to the heating water return that power is provided by water circulating pump, after heat exchange, the water temperature of heating water raises, then, supply with the heating system heat or supply with the bath water system thermal through the heating outlet pipe through plate type heat exchanger, when heat demand, at first start water circulating pump, open blower fan again, after treating that blast switch is connected, ignition device, gas valve is opened, and the flame detecting electrode detection is to flame, light a fire successfully, the wall hanging stove enters normal operation.Being in operation also can automatically adjust according to running temperature and design temperature difference, particularly after temperature reaches design temperature the gas valve aperture is reduced, and only keeps the temperature of water with little fire, saves combustion gas to greatest extent.When switching to the bath hot water pattern, water flow switch is connected, and at first whether hydraulic pressure is normal in the check system, drives triple valve then to the bathing position.The interior interior bath water of heating recirculated water heating plate type heat exchanger of sealing and circulating this moment up to not needing bath hot water, is transformed into heating mode again.Be provided with safety valve in the system, the overtemperature prote device, by-passing valve, safety devices such as temperature sensor, being in operation system overheat occurs and pressure does not meet and can autostop during fault such as lack of water, to guarantee safety.The high-temperature flue gas that burning produces is discharged gas two-purpose stove outside by blower fan, and wherein the heat more than 10% is discharged into atmosphere with flue gas, the waste heat in the flue gas can't be made full use of, so the thermal efficiency is lower, has caused great energy waste.
The utility model content
The utility model provides a kind of novel condensing heating/hot water gas two-purpose stove of high thermal efficiency in order to solve the prior art deficiency.
The technical scheme that the utility model adopts in order to solve the problems of the technologies described above is as follows:
A kind of novel condensing heating/hot water gas two-purpose stove, comprise shell body and be arranged on housing interior combustion chamber, main heat exchanger, inlet and outlet pipe, safety device and control device, combustion chamber, main heat exchanger all are in the confined chamber, confined chamber also is communicated with smoke discharging passage and outlet, the smoke discharging channel outlet is provided with the blower fan by blast switch control, and inlet and outlet pipe is provided with water circulating pump, water compensating valve and hot water effluent's triple valve and plate type heat exchanger; It is characterized in that: also be provided with the condenser that is made of afterheat heat exchanger in the smoke discharging passage, inlet pipeline connects the main heat exchanger pipeline again behind afterheat heat exchanger, and the afterheat heat exchanger bottom also is provided with condensed water collecting device.
Described safety device comprises safety valve, overtemperature prote device, Pressure gauge and the vent valve that is arranged on the inlet and outlet pipe.
The condensate draining pipe that described condensed water collecting device joins by the condensed water catch tray that the afterheat heat exchanger bottom is set, with the condensed water catch tray constitutes; On condensate draining pipe, also be provided with the condensed water averager and be arranged on the condensed water collecting device of afterheat heat exchanger below.Described afterheat heat exchanger, averager, condensate collector, blower fan and smoke pipe all adopt resistant material.
Described afterheat heat exchanger adopts stainless steel or aluminum alloy materials, and the surface is provided with the protective layer that prevents sour corrosion.
Described plate type heat exchanger connects bath hot water pipe and outlet, bathing cold water inlet, and bathing is provided with the bath hot water priority switch with cold water inlet.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: set up a cover flue gas condensing system, the heat of the flue gas that fully absorbs fuel gas buring and produced by two heat exchangers, heating water return is successively by afterheat heat exchanger and main heat exchanger, twice heat exchange of high-temperature flue gas adverse current with heat, fully absorbed the heat of flue gas, steam is separated out with condensed water, emits the sensible heat and the latent heat of vaporization.Thereby significantly improved the thermal efficiency, exhaust gas temperature is reduced greatly.Be provided with the condensed water catch tray below the afterheat heat exchanger, the condensed water that will contain acid collects and imports in the averager, and averager is discharged in the cold water and back by pipeline, handled the problem of condensed water environmental pollution.Afterheat heat exchanger, averager, condensed water catch tray, blower fan and smoke pipe all adopt resistant material, have solved the cold end corrosion problem, have prolonged the service life of burnt gas wall hanging furnace.Because exhaust gas temperature is low, and the bags water collector that is condensed separates, and wall hanging stove resistance increases, and draft reduces, and therefore requires Forced discharge fan that bigger draft is arranged, and makes smoke evacuation smooth and easy, has kept the basicly stable of air coefficient, the stability of burning.
