Abstract
The utility model provides a gas combustor which can reduce the content of harmful gases such as nitric oxide in smoke gas and adjust ejective flame length, comprising a combustor main body, a combustion head, an axial ventilation terminal, a radial wind cyclone, a gas cyclone, and ignition holes. The gas combustor is characterized in that combustion-supporting air jets respectively from the combustor in an axial direction and a radial direction. Long flame can be achieved by enlarging axial air and reducing radial air, short flame can be achieved by enlarging the radial air and reducing the axial air, and therefore, the goal of adjusting the flame length can be achieved.
Description
The utility model relates to a kind of adjustable flame length and reduces the special equipment of content of nitrogen oxide in the burnt gas.
All adopt general gas burner on the present domestic metallurgical industry rough rolling mill soaking pit, this burner can not be regulated the length of flame, makes top single fire mouth soaking pit (also claiming U type flame soaking pit) inhomogeneous along the furnace temperature of furnace superintendent axis direction.
The purpose of this utility model is to be to avoid above-mentioned deficiency of the prior art and when a kind of burning coal gas fuel is provided, can obtain to contain the gas burner of the lower flue gas of content of nitrogen oxide and the change length of flame, satisfying U type flame soaking pit along all even requirement that contains lower content of nitrogen oxide in flue gas of furnace temperature on the furnace superintendent axis, this burner is applicable to that the stove cellar for storing things that needs to regulate the length of flame and reduce content of nitrogen oxide in the flue gas is gone up and uses.
The utility model mainly aweather partly form by burner body, burner head, coal gas blowoff, footpath by blowoff, axial wind blowoff etc.Footpath aweather blowoff comprises aweather cyclone of aweather aweather adapter of fairlead, footpath of footpath, footpath.Axially the wind blowoff is equipped with axial ventilation terminal.Characteristics of the present utility model are: combustion air is from the radial and axial burner of introducing respectively, when the long flame of needs, the axial air flow scales up, otherwise when needing weak point flame, the radial air amount that scales up reduces the axial air amount, thereby has changed the length of flame, in addition, the axial ventilation terminal that axial air is played guide functions is housed in the burner front portion.This ventilation terminal along the circumferential direction is evenly equipped with 4-6 perforation, and air flows out from perforation, all obtains axial multithread thigh jet.And be relative negative pressuren zone between the stream thigh, high-temperature flue gas is back to by negative pressuren zone near the burner nozzle, has improved flame root jet temperature, has reduced flame localized hyperthermia district's temperature.Thereby reached the purpose that reduces nitrogen oxide pernicious gas in the flue gas, reduces atmosphere pollution.This ventilation terminal can also block the radiation of furnace high-temperature flue gas to burner inside, makes burner that a working environment preferably be arranged.Also available steel pipe along the circumferential direction is welded into equally distributed ventilation terminal.Radial swirler adopts the rotating vane of installing at a certain angle to constitute, and significantly reduce than the sensitiveness of tubular structure to radiation of burner hearth, so prolongs service life relatively.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 low Nox is adjustable flame burner structural representation;
The axial ventilation terminal front view of Fig. 2;
The axial ventilation terminal vertical view of Fig. 3;
Fig. 4 footpath is cyclone aweather.
The drawing explanation:
Burner body, 2. the footpath aweather take over, 3. aweather fairlead, 4. coal gas bleed pipe, 5. burner head, 6. axially ventilation terminal, 7. installing plate, 8. trip bolt, 9. coal gas cyclone, 10. fire hole, 11. sealing flanges, 12. refractory materials, 13. footpaths cyclone, 14. footpaths swirler blades aweather aweather of footpath.
Coal gas is introduced by direction shown in the figure, by coal gas cyclone (9) coal gas is rotated, to accelerate from the rotary speed of coal gas bleed pipe (4) ejection coal gas, improve the blending degree of coal gas and air, coal gas cyclone (9) is fastened on the coal gas bleed pipe (4) by trip bolt (8).Radial air is to be caused by the tangential direction shown in the figure directly aweather to take in (2), by aweather fairlead (3) and aweather directly aweather rotation ejection and coal gas blending of cyclone (13) of footpath of footpath.Radial swirler adopts the rotating vane of installing at a certain angle (14) to constitute.Axially wind is caused in the burner body (1) by direction shown in the figure; deliver in the burner head (5) through axial ventilation terminal (6), axially ventilation terminal (6) is mounted on the burner head (5), and uses bolting; there is loose refractory (12) to serve as a contrast in the burner head (5), with the protection burner.Igniting is to be undertaken by fire hole (10).Sealing flange (11) is aweather taken over the sealing of (2) and coal gas bleed pipe (4) with the footpath, by installing plate (7) whole burner is installed on the furnace wall steel plate.
The utility model can make U type flame soaking pit even along the furnace superintendent axial temperature, and the content of nitrogen oxide in the burnt gas is reduced, and reduces the pollution to atmosphere.And further improved its service life.
