Abstract
The utility model discloses an energy-saving and environmentally-friendly fuel oil, gas and steam boiler which comprises a combustion engine, a boiler container, a tempering chamber, a first return smoke pipe, a second return smoke pipe, a boiler smoke outlet, a chimney, a water inlet, a boiler water pump, a main air valve and a safety valve. Besides, the energy-saving and environmentally-friendly fuel oil, gas and steam boiler also comprises an afterheat recycling device; the afterheat recycling device is particularly a gas-water heat exchanging device and is arranged between the boiler smoke outlet and the chimney; and water of the water inlet can be communicated to an inlet of the boiler water pump after passing through the afterheat recycling device. The energy-saving and environmentally-friendly fuel oil, gas and steam boiler makes full use of heat energy carried by smoke, so that the thermal efficiency is improved, hot water discharged by a smoke recycling device after heat exchanging can directly enter the boiler, the water supply temperature of the boiler is increased, the energy-saving effect is obvious and the running cost is saved.
Description
Technical field
The utility model relates to a kind of energy-efficient fuel-firing gas-firing steam boiler.
Background technology
The fuel-firing gas-firing steam boiler in the whole nation mostly is not with the flue gas retracting device at present, a large amount of heat energy that boiler smoke carries all directly are discharged in the atmosphere, cause its actual operating efficiency to have only about 85～90%, wasted a large amount of heat energy, increased the operating cost of boiler; Also caused the pollution of atmosphere.
The utility model content
The purpose of this utility model is to provide a kind of novel energy-saving environment-friendly type fuel-firing gas-firing steam boiler.To realize making full use of a large amount of heat energy that flue gas carries, improve boiler efficiency, save the energy, reduce the operating cost and the pollution that reduces atmosphere of boiler.
The technical solution of the utility model is: comprise combustor, flue, reversing chamber, the first backhaul smoke pipe and the second backhaul smoke pipe, boiler flue gas outlet, chimney, water inlet, boiler water pump, main air valve and safety valve, it is characterized in that also comprising a waste-heat recovery device, this waste-heat recovery device is the air-water heat-exchange device, place boiler flue gas outlet and chimney between the two, the water of water inlet is by being communicated to the import of boiler water pump again after this waste-heat recovery device.
According to the further setting to technique scheme, aforementioned fuel-firing gas-firing steam boiler is horizontal three backhaul wetting back-type structure boilers.Be provided with some smoke pipes with the parallel placement of interface of boiler flue gas outlet in the waste-heat recovery device; On the waste-heat recovery device shell, be provided with into cold water pipe and hot water outlet pipe; Be provided with blow-off pipe in the waste-heat recovery device bottom, top is provided with atmospheric communicating pipe.
The utility model boiler has made full use of a large amount of heat energy that flue gas carries, improved the thermal efficiency greatly, the hot water of discharging after the heat exchange of flue gas retracting device directly enters boiler, improved the feed temperature of boiler, energy-saving efficiency is remarkable, the thermal efficiency improves, and saves operating cost, has also reduced the pollution of flue gas to atmosphere; And the equipment flue gas resistance that increases is little, need not to set up any auxiliary fume extractor again, can make the flue gas flow of whole system unaffected, and the compact appearance design makes the occupation of land space reach minimum.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing:
The energy saving and environment friendly fuel-firing gas-firing steam boiler of a kind of preferred embodiment of the present utility model comprises combustor 1, flue 2, reversing chamber, the first backhaul smoke pipe 3 and the second backhaul smoke pipe 4, boiler flue gas outlet 5, chimney 8, water inlet 9, boiler water pump 14, main air valve 12 and safety valve 13.The fuel-firing gas-firing steam boiler is horizontal three backhaul wetting back-type structure boilers.Waste-heat recovery device is the air-water heat-exchange device, places boiler flue gas outlet 5 and chimney 8 between the two, is provided with some smoke pipes 6 with the parallel placement of interface of boiler flue gas outlet in the waste-heat recovery device.The water of water inlet is by being communicated to the import of boiler water pump 14 again after this waste-heat recovery device.
On the waste-heat recovery device shell, be provided with into cold water pipe 9 and hot water outlet pipe 10; Be provided with blow-off pipe in the waste-heat recovery device bottom, top is provided with atmospheric communicating pipe 11.
Fuel such as oil gas are through combustor 1 igniting, and in flue 2 internal combustion, through the first backhaul smoke pipe, 3 second backhaul smoke pipes 4, boiler flue gas outlet 5 flue gases enter in the chimney through exporting 7 the smoke pipe 6 of waste-heat recovery device in and the water heat exchange flue gas by reversing chamber; Demineralized water enters from water inlet, enters boiler water pump through retracting device heating back from delivery port, and by entering boiler after the water pump pressurization, water is discharged usefulness for productive life from main air valve behind the heating evaporation in boiler.
The utility model boiler has made full use of a large amount of heat energy that flue gas carries, improved the thermal efficiency greatly, the hot water of discharging after the heat exchange of flue gas retracting device directly enters boiler, the feed temperature of boiler generally can be brought up to 65 ℃ by 20 ℃, energy-saving efficiency is remarkable, and exhaust gas temperature is reduced to 110 ℃ from 220 ℃; The thermal efficiency improves 8%, and it is about more than 100,000 yuan to save operating cost the whole year, has also significantly reduced the pollution of flue gas to atmosphere; And the equipment flue gas resistance that once added is little, need not to set up any auxiliary fume extractor again, can make the flue gas flow of whole system unaffected, and the compact appearance design makes the occupation of land space reach minimum.
This product thermal efficiency after the process improvement reaches and exceeds national GB 24500-2009 Industrial Boiler efficiency limit value and efficiency grade primary standard more than 94%.
