Abstract
The utility model relates to an internally fired boiler which comprises a furnace body and a furnace hearth arranged in the furnace body. A towering tube is disposed on the top of the furnace hearth. The towering tube is communicated with the interior of the furnace hearth. The top of the towering tube is exposed outside the furnace body. The top of the towering tube is in an arch structure. A heat water pipe of a snakelike structure is disposed on the lower portion of the arch structure of the furnace hearth. The internally fired boiler can improve heat utilization rate and save fuels.
Description
Technical field
The utility model relates to the boiler technology field, particularly relates to a kind of energy-efficient internally fired boiler.
Background technology
Boiler is a kind of energy conversion, to the energy of boiler input the forms such as heat energy of chemical energy in the fuel, electric energy, high-temperature flue gas are arranged, and through the boiler conversion, outwards output has steam, high-temperature water or the organic heat carrier of certain heat energy.The original meaning of pot refers to the water container that on fire, heats, and stove refers to the place of combustion fuel, and boiler comprises pot and stove two large divisions.Hot water that produces in the boiler or steam can also can convert mechanical energy into through Steam Power Equipment, or convert mechanical energy into electric energy through generator more directly for commercial production and people's lives provide required heat energy.Provide the boiler of hot water to be called hot-water boiler, be mainly used in life, a small amount of application is also arranged in the commercial production.The boiler that produces steam is called steam boiler, often abbreviates boiler as, is used for thermal power station, boats and ships, locomotive and industrial and mining enterprises more.
Existing boiler all is under impact tube, to arrange several transverse tubes, and burner hearth is square, and is lower to the utilization rate of heat; Heats to water is undesirable, when normally the intensity of a fire is prosperous with heating installation warm, it is just not warm that the intensity of a fire is not prosperous; Take very much fuel, and can be colder evening the time.
Summary of the invention
The utility model technical problem to be solved provides a kind of internally fired boiler, can improve the utilization rate and the fuel saving of heat.
The utility model solves the technical scheme that its technical problem adopted: a kind of internally fired boiler is provided; Comprise body of heater and the flue that is arranged in the body of heater; The top of said flue is equipped with impact tube, the internal communication of said impact tube and flue, and the top of impact tube is exposed at the outside of body of heater; The top of said flue is domes, and the below, top of said flue domes is provided with the hot-water line of serpentine configuration.
The said flue outside also is provided with heat-insulation layer.
Be provided with the thermal-arrest plate in the said flue, the two ends of said thermal-arrest plate are passed said flue and are linked to each other with the inner chamber of said body of heater.
Said impact tube bottom is provided with the waste heat chamber, the indoor transverse tube that is provided with of said waste heat.
Beneficial effect
Owing to adopted above-mentioned technical scheme; The utility model compared with prior art; Have following advantage and good effect: the roof of the furnace of the utility model adopts domes, and in flue, to have set up be hot plate, and the heat that makes fuel produce better heats water; Can practice thrift 20% fuel during the same temperature of water temperature rise.Impact tube is provided with the waste heat chamber simultaneously, makes that the waste heat in the flue gas has obtained utilization.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The embodiment of the utility model relates to a kind of internally fired boiler; As shown in Figure 1, comprise body of heater 1 and the flue 2 that is arranged in the body of heater 1, the top of said flue 2 is equipped with impact tube 3; The internal communication of said impact tube 3 and flue 2; The top of impact tube 3 is exposed at the outside of body of heater 1, and the top of said flue 2 is domes, and the below, top of said flue 2 domes is provided with the hot-water line 4 of serpentine configuration.Said flue 2 outsides also are provided with heat-insulation layer 5, because the heat-blocking action of heat-insulation layer 5 can prevent that the temperature in the flue 2 from descending too fast.Be provided with thermal-arrest plate 6 in the said flue 2, the two ends of said thermal-arrest plate 6 are passed said flue 2 and are linked to each other with the inner chamber of said body of heater 1.Said impact tube 3 bottoms are provided with waste heat chamber 7, and said waste heat chamber 7 medium dip solid matters are furnished with transverse tube 8.
When the utility model uses; In flue, add fuel; Fuel combustion is heated the water in the water cavity (being the space that forms between body of heater and the flue), also the water in hot-water line and the thermal-arrest plate is heated simultaneously, and the flue gas of generation is discharged through impact tube; In discharge process, again the transverse tube in the waste heat chamber is heated.Transverse tube in hot-water line, thermal-arrest plate and the waste heat chamber all is communicated with water cavity; Water in the water cavity can be circulated in the transverse tube in said hot-water line, thermal-arrest plate, the waste heat chamber; Make water by better heating, after water is heated, from delivery port efferent tract heating pipeline, heat.
Be not difficult to find that the roof of the furnace of the utility model adopts domes, and in flue, to have set up be hot plate, the heat that makes fuel produce better heats water, can practice thrift 20% fuel during the same temperature of water temperature rise.Impact tube is provided with the waste heat chamber simultaneously, makes that the waste heat in the flue gas has obtained utilization.
