Abstract
The utility model relates to a high-efficiency gas burning nozzle for various heating furnaces, composed of an outer sleeve 1, a spraying nozzle 2, a spraying nozzle fixed sleeve 3, first stage, second stage and third stage burning chambers 7, 9, 12, first stage, second stage and third stage air regulating plates 8, 10, 13, an air regulating sleeve 15, swivel bushings 19, 20, 21, etc. The high-efficiency gas burning nozzle uses three stages to segment and two stages to rotatablely mix to mix natural gas and combustion air uniformly, so that flame is enlarged, heating temperature is high, perfect burning is realized, and the efficiency of heating furnaces reaches to more than 85%. Meantime, with the air regulating device, the utility model can reasonably control air intake quantity to avoid blowing to extinguish fire.
Description
The utility model relates to a kind of high efficiency burnt gas fire that is used for various heating furnaces and chews.
Existing heating furnace combustion gas fire is chewed mostly and is chewed tail end suction air by combustion chamber draft from fire, with fuel gas mixing after-combustion.This burner is widely used on the various heating furnaces owing to simple in structure.But, because single mixing quantitatively can not rationally be mated natural gas and combustion air, cause incomplete combustion, there are more CO and hydrocarbon fuel gas to drain with cigarette.Like this, not only contaminated environment wastes energy again, and because flame is short, temperature is low, is difficult to improve stove and imitates.
Task of the present utility model is to provide a kind of new and effective combustion gas fire to chew, and this kind fire is chewed and can be guaranteed that natural gas evenly mixes with combustion air, and it is long to reach the flame jet length, the purpose that efficiency of combustion is high.
The utility model is to realize like this.It is by overcoat 1, nozzle 2, nozzle fixed cover 3, by cap 4, lining 5,14,17, one, two, three combustion chamber 7,9,12, mixing chamber 6, one, two, three air regulating board 8,10,13, steady pin 11, air regulating sleeve 15, fixed head 16, fixedly gusset 18, rotary liner 19,20,21, fixed screw 22 and seat clay 23 are formed.Its structure and assembling feature are: be disposed with lining 14,5, nozzle fixed cover 3 in the overcoat 1 from outside to inside; Be disposed with mixing chamber 6, one, two, three combustion chamber 7,9,12 and one, two, three air regulating board 8,10,13 correspondingly between the lining 14,5 vertically, be filled with seat clay 23 in the cavity between lining 5,14 and the secondary air regulating board 10; Three grades of combustion chambers 12 and lining 14 front portions are welded with one-level rotary liner 21 and left and right rotary liner 19,20 respectively, and lining 14 front end returning apparatus have lining 17, and fixed head 16 is housed; Device has nozzle 2 in the nozzle fixed cover 3, and the one end links to each other with mixing chamber 6, and other end device has by cap 4; Two, three grades of 9,12 of combustion chambers are connected to a fixed with steady pin 11; Overcoat 1 opening end outside is set with transfers fire cover 15, and both are fixing with fixed screw 22, the overcoat head by 6 fixedly gusset 18 be fixed on the lining 14.Whole fire is chewed by fixed head 16 and is fixed on the heating furnace burner, after the natural gas with certain pressure enters one-level combustion chamber 7 from the nozzle ejection, volume increases and forms negative pressure, sucking surrounding air mixes with it, enter secondary combustion chamber 9 again, volume further increases, suck again and enter three grades of combustion chambers 12 after surrounding air is mixed, a part is directly participated in burning, another part produces rotation by one-level rotary liner 21, acceleration mixing back, produces swirl flame and sprays into burner hearth through left and right rotary liner 19,20 with the remaining gaseous mixture of burning.When the little fire of needs control, can reduce the air inlet by adjusting air regulating sleeve 15.Since turning effort, the flame jet length that not only extended, and improved flame temperature on every side, and it is more even that natural gas is mixed with air, and it is more complete to burn.
The utility model compared with prior art, its characteristics are to have adopted the rotation of three grades of segmentations, secondary to mix, and make natural gas and combustion air mix flame and increase, the heating-up temperature height realizes that plenary session burns, and heater efficiency is reached more than 85%.Simultaneously, owing to be provided with louver, intake can rationally be controlled, the fire extinguishing of avoiding blowing.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
In the utility model, overcoat 1 is a steel pipe, is furnished with 4 row's fresh air inlets above, and afterbody blocks with steel plate.Nozzle 2 is a reducing pipe, and tail end has pin thread, in order to be connected and fixed with fixed cover 3.Mixing chamber 6 is the pipe of a front opening, and the circular hole that 5 covers match is left and serves as a contrast at the tail end middle part, and row's fresh air inlet is arranged on the periphery.One, two, three combustion chamber 7,9,12 is respectively the pipe that is rolled into the 1Cr13 steel plate.One, two, three air regulating board 8,10,13 is the 45# steel plate and makes, and the centre has wind adjusting hole.Left and right rotary liner 19,20 is 45# steel pipe, and periphery has the left and right pin thread that revolves respectively.Nozzle lining 14 is a pipe, and 4 row's air admission holes are arranged above.
