Abstract
The utility model discloses a safe and energy-saving condensing gas water heater, which comprises a burner, a heat exchanger, a fume exhaust and air inlet device, a cold water inlet, a hot water outlet, a fume exhaust port, an air inlet and a gas inlet, wherein, the burner is a full premixing air burner, and a fan is arranged above the burner; the heat exchanger is a heat exchanger for sensible heat and latent heat, and a condensate pipe is arranged on the lower surface of the heat exchanger; a gas and air proportional controller is also arranged on the side of the burner. The utility model has the advantages of good energy saving effect, compact structure, small volume, reduction of the pollution of harmful gas, and safety.
Description
The utility model relates to the water heating apparatus of burning gases fuel.
At present, the gas heater of selling on the market only utilizes the sensible heat that produces behind the fuel gas buring in the flue gas, and its flue-gas temperature all surpasses 110 ℃～130 ℃, otherwise the condensate water that produces can drop on the burner surface in the water heater, influences combustion efficiency, damages burner.Because the water heater outer wall heat loss (accounting for 2%) that has except everybody in the heat loss of water heater, all the other most heat loss all belong to heat loss due to exhaust gas, and flue-gas temperature is high more, heat loss due to exhaust gas is big more, and the thermal efficiency is low more.Because the exhaust gas temperature of common gas heater is not less than 110 ℃, and have bigger excess air to participate in burning, so its thermal efficiency is about 80～85%, is difficult to surpass 90%.Also there is safety problem in the fume exhausting type of common water heater in addition.
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of safe, clean, energy-conservation, condensed type combustion gas water heating apparatus that hot-fluid is downward is provided.
The purpose of this utility model is achieved by following technical proposals.
The utility model safety, energy-conservation condensed type combustion gas water heating apparatus comprises burner, heat exchanger, the smoke evacuation air-intake device, cold water inlet, hot water outlet, exhaust opening, air inlet and fuel gas inlet, described burner adopts full premix air burner, blower fan is arranged on the top of described full premix air burner, described heat exchanger adopts a kind of sensible heat and latent heat heat exchange and with the dirty sensible heat of condensed water, latent heat exchanger, described heat exchanger be positioned at full premix air burner below, condensate pipe be arranged on heat exchanger below, described burner is other also to be provided with the gas-air proportional controller, in order to keep combustion gas and air in the optimal proportion scope.
The head of described full premix air burner is made by metallic fiber and other material fiber carriers, porous ceramic plate and bimetallic net.The exhaust opening of described smoke evacuation air-intake device and air inlet be suit mutually, also can be arranged apart.Described combustion gas water heating apparatus also can add the computer control panel, in order to devices such as control temperature, pressure, flow sensor and igniting automatically, flame detection, blowout protection, hot water constant temperatures.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
In the drawings, condensed type combustion gas water heating apparatus of the present utility model, be gas heater, constitute by blower fan 1, gas-air proportional controller 2, full premix air burner 3, sensible heat, latent heat exchanger 5, condensate pipe 6, exhaust opening 7, air inlet 8, computer controller 9, cold water inlet 11, hot water outlet 12 and fuel gas inlet 13.
Blower fan 1 is arranged on described full premix air burner 3 tops, gas-air proportional controller 2 is arranged in the described combustion gas water heating apparatus, sensible heat, latent heat exchanger 5 be arranged on full premix air burner 3 below, condensate pipe 6 be arranged on sensible heat, latent heat exchanger 5 below.
Contain blower fan 1, gas-air proportional controller 2, the full premix air burner 3 of motor, form one and can make flame reversing, the burner under the hot flue gas flow direction.Blower fan 1 is supplied with the fresh air that burning needs, and combustion gas enters gas-air proportional controller 2 by fuel gas inlet 13, and is blended on the burner head 4 of full premix air burner 3 with fresh air and burns.The ratio of combustion gas and air can keep designing combustion gas, the air optimal proportion of needs by the 2 strict controls of gas-air proportional controller.Burner head 4 is made by the porous ceramic plate of metal fiber carrier or 10 millimeters thick.The flame of this combustion apparatus is because the pressure that blower fan 1 produces can make the flame reversing, and hot flue gas flows downward, and the condensate water flow direction of getting off with condensation in the flue gas is consistent, makes the water heater compact conformation.
Hot flue gas is passed to cold water through sensible heat, latent heat exchanger 5 with heat.Condensed water enters sewer by condensate pipe 6.
Blower fan 1 is discharged flue gas outdoor from the exhaust opening of smoke evacuation air-intake device 7 by pressure, outdoor fresh air is sucked air inlet 8.The exhaust opening of described smoke evacuation air-intake device 7, air inlet 8 can mutual sheathing, and the exhaust opening of the air-intake device 7 of discharging fume as required and air inlet 8 also can be arranged apart.
Cold water is entered by sensible heat, latent heat exchanger 5 belows, and in order to water recovery, hot water flows out from hot water outlet 12.
Water heater is installed on the wall 10, also can be installed on the ground.
Safe, energy-conservation condensed type combustion gas water heating apparatus of the present utility model comprises boiler and water heater; it also can be provided with computer control panel 9 as required; sensors such as unified control temperature, pressure, flow; and devices such as automatically igniting, flame detection, blowout protection, hot water constant temperature, guarantee water heater safety, convenient use.
The beneficial effects of the utility model are: 1. energy-conservation, improved the thermal efficiency, and the thermal efficiency can reach more than 98%. 2. compact conformation, volume are little. 3. reduce and pollute, reduce the pollution of pernicious gas NOx and CO, be conducive to the chamber Interior air cleaning, fresh. 4. easy to use, can use various combustion gas. 5. safe and reliable, the smoke evacuation with Air intake is realized by blower fan, can prevent that flue gas from pouring in down a chimney, and guarantees indoor not anoxic, and accidents happened.
