Abstract
A normal-pressure high-efficiency fuel oil and gas water heater comprises a furnace body, a burner, a fire tube, a smoke tube, a flue, a heat exchange tube and an overflow tube part. The cavity in the furnace body is filled with pure heat medium water, and the smoke tubes are arranged in multiple layers at the periphery of the fire tube. The inlet of the fire tube is provided with a smoke chamber divided into an inner ring and an outer ring. The utility model discloses carry out the conversion of secondary heat energy, carry out reversal formula multipass heating, make the heat of fuel can make full use of, can replace boiler and heat exchanger directly to public place and resident's living district realization central heating, heating and provide life with hot water, the small investment, the thermal efficiency is high, keeps ordinary pressure, safe and reliable in the furnace body simultaneously.
Description
The utility model relates to a kind of fuel-firing gas-firing water heater, particularly a kind of normal pressure high efficiency fuel gas water-heating furnace that carries out the heating of reversible type multipass.
Along with the progress of society and the raising of people's living standard, can central heating, heating, provide life to be applied to factory, office, school, hotel, market, dining room, bathroom, hospital, public place of entertainment resident living sub-district in one's power with hot water and for lithium bromide absorbing central air provides the multipurpose hot water station of the thermal source that freezes increasingly extensively.Existing hot water station generally adopts boiler to produce steam, heats needed hot water by steam by heat exchanger again.For boiler, the high-temperature flue gas that fuel produces after combustion chambers burn is general direct to enter atmosphere through flue by chimney, can only carry out the one way heating, the flue-gas temperature height of discharge, and not fully burning, therefore, the thermal efficiency is lower, big energy-consuming.
The purpose of this utility model is to overcome the weak point of existing hot water station equipment, provides a kind of and carries out the heating of reversible type multipass, thermal efficiency height, few normal pressure high efficiency fuel gas water-heating furnace consumes energy.
The technical solution of the utility model is: normal pressure high efficiency fuel gas water-heating furnace comprises base, body of heater, burner, fire tube, smoke pipe, flue, heat exchanger tube, overflow pipe part, and the cavity in the body of heater is equipped with pure heat medium water.Described smoke pipe is arranged in the peripheral multilayer of fire tube, is provided with the smoke-box that is divided into inside and outside circle between fire tube and the burner, and the inner ring smoke-box connects catch fire tube inner chamber and nexine smoke pipe inner chamber, and the outer ring smoke-box is connecting outer smoke pipe inner chamber and flue inner chamber.
Above-mentioned smoke pipe is the circular ring type multilayer along the periphery of fire tube arranges, and also can be semicircle ring type multilayer along the periphery on fire tube top and arrange.Described multilayer is arranged, and to be generally the innner and outer two-layer.
Fuel oil or combustion gas spray to the fire tube through burner, and gas fume after burning enters smoke pipe, and wherein flue gas is less because of proportion fully in burning, generally enters outer smoke pipe, enters flue through the outer ring smoke-box again and enters atmosphere; Not clean-burning flue gas generally enters the nexine smoke pipe, under the suction function at burner nozzle place, enters the fire tube once more through the inner ring smoke-box, and the heating of reversible type multipass is carried out in the heat release of further burning.Thereby the raising thermal efficiency, power consumption is few, saves fuel oil or combustion gas.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
This water heater is installed on the base 1, and burner 2 is fixed in the stove outside.Communicate with fire tube 9.The arrangement space of the heat exchanger tube 6 of flue 4 above being arranged in the fire tube is passed, and stretches out outside the stove.Body of heater 3 internal cavities are equipped with pure distilled water 8, and the body of heater outside is provided with overflow pipe 7.Two-layer periphery along fire tube top, 5 fens innner and outers of smoke pipe is the semicircle ring type and arranges, be provided with the smoke-box 10 that is divided into inside and outside circle between fire tube and the burner, the inner ring smoke-box connects catch fire tube inner chamber and nexine smoke pipe inner chamber, and the outer ring smoke-box is connecting outer smoke pipe inner chamber and flue inner chamber.
Claims (4)
1, a kind of normal pressure high efficiency fuel gas water-heating furnace, comprise base, body of heater, burner, fire tube, smoke pipe, flue, heat exchanger tube part, cavity in the body of heater is equipped with pure heat medium water, it is characterized in that smoke pipe arranges in the peripheral multilayer of fire tube, be provided with the smoke-box that is divided into inside and outside circle between fire tube and the burner, the inner ring smoke-box connects the inner chamber of catch fire tube inner chamber and nexine smoke pipe, and the outer ring smoke-box is connecting outer smoke pipe inner chamber and flue inner chamber.
2,, it is characterized in that described smoke pipe is the circular ring type multilayer along the periphery of fire tube and arranges by the described water heater of claim 1.
3,, it is characterized in that described smoke pipe is semicircle ring type multilayer along the periphery on fire tube top and arranges by the described water heater of claim 1.
4, by claim 2 or 3 described water heaters, it is characterized in that described smoke pipe arrange for the innner and outer two-layer.
