Description
Technical field
The present invention relates to a kind of venturi burner, particularly relate to a kind of can the venturi burner of efficient burning fuel gas.
Background technology
In petrochemical equipment, unnecessary, harmful, the unbalanced waste gas discharged in the timely process for producing device of Venting and Flare Stack System energy, and the defective gas produced when can process test run, start-stop car, and a large amount of gases of instantaneous releasing during accident, assurance device is normal, safe operation.Torch burning will keep the stability of flame, and the flame crest of flame of normal table should on the top of torch vertical tube, and flared gases leaves the speed of flare tip and burning velocity adapts.But if the speed of gas is excessive, the flame on torch vertical tube top is raised on burner and mixes with air turbulence, can produce " from flame ", and namely flame can leave the certain distance in flare tip top, and serious vibration occurs.If speed increases again, flame can continue, toward floating, will have the danger of fray-out of flame, this cries " de-fire ", and by making, gas that is poisonous, that have burn into inflammable and explosive is in a large number excessive, diffusion for this, not only will cause casualties, contaminated environment, serious meeting causes blast, fire.Such as, and if fuel combustion incomplete combustion, inefficient burning, will produce a large amount of noxious emission, carbon monoxide, nitrogen oxide etc.
Summary of the invention
In view of this, the present invention proposes a kind of efficient venturi burner solving at least one the problems referred to above.
The invention provides a kind of efficient venturi burner, comprise Venturi tube, nozzle and flame holder, described Venturi tube has inlet end and outlet side, described nozzle is located at described inlet end, described flame holder is located at described outlet side, described flame holder comprises the sleeve be connected with the outlet side of described Venturi tube and the flame stabilization ring be arranged in described sleeve, described flame stabilization ring is provided with centre bore and the equally distributed through hole of a circle around described centre bore, and the wall of described centre bore is provided with along the axially extended some grooves of described flame stabilization ring.
In one embodiment, the bottom of described some grooves is arc is wavy to make the wall of described centre bore.
In one embodiment, each groove is between two adjacent through holes.
In one embodiment, each groove has two relative planomural faces.
In one embodiment, described two relative planomural faces are connected by a cambered surface in the bottom of described groove.
In one embodiment, the distance between described two relative planomural faces is reducing gradually towards the direction of described bottom.
In sum, the invention provides a kind of efficient venturi burner, above-mentioned two embodiments all adopt and axially to extend thus the mode forming some grooves makes the wall area of centre bore increase along flame stabilization ring on the wall of centre bore, therefore during fuel gas, flame outer surface can be made can to contact to make fuel gas Thorough combustion with more air, lower carbon monoxide and discharged nitrous oxides, shorten flame height simultaneously, reduce light pollution.

Detailed description of the invention
Before describing the embodiments in more detail, it should be understood that and the invention is not restricted to detailed construction in the application hereafter or described in accompanying drawing or arrangement of elements.The present invention can be the embodiment that alternate manner realizes.And, should be appreciated that wording used herein and term are only used as to describe purposes, should being construed as limiting property not explain.Similar wording meant and comprised item listed thereafter, its equivalent and other additional things " comprising " used herein, " comprising ", " having " etc.Particularly, when describing " certain element ", the quantity that the present invention does not limit this element is one, also can comprise multiple.
Fig. 1 is the schematic perspective view of venturi burner, and as shown in Figure 1, efficient venturi burner comprises Venturi tube 2, nozzle 3 and flame holder 4, Venturi tube 2 has inlet end 5 and outlet side 6, wherein, nozzle 3 is located at inlet end 5, and flame holder 4 is installed in outlet side 6.Flame holder 4 comprises the sleeve 7 be connected with the outlet side 6 of Venturi tube 2 and the flame stabilization ring 8 be arranged in sleeve 7.
Please refer to Fig. 2, Fig. 2 is the schematic top plan view of flame stabilization ring in an embodiment.Flame stabilization ring 8 is provided with centre bore 9 and the equally distributed through hole 10 of a circle around centre bore 9.The region that flame stabilization ring 8 periphery and sleeve 7 surround forms district in whirlpool, and through hole 10 is just to this district in whirlpool.The gaseous mixture of small part air and fuel enters district in whirlpool by through hole 10, forms the flammule around the large flame of centre bore that a circle is stable.The wall of centre bore 9 is also provided with along the axially extended some grooves 11 of flame stabilization ring 8.The formation of groove 11 makes the wall area of centre bore 9 increase, and the area of the flame that the fuel combustion therefore sprayed from centre bore 9 is formed and contacting external air also can increase.Therefore, more air will be had and participate in burning, and improve the burning degree of fuel, effectively reduce noxious emission, the generation of such as carbon monoxide and nitrogen oxide.Meanwhile, due to sufficient combustion, the height of flame is also minimized, thus reduces light pollution, reduces the height of protective cover.
In an illustrated embodiment, it is wavy that the bottom of some grooves 11 is set to arc to make the wall of centre bore 9, and each groove 11 is between two adjacent through holes 10.
Please refer to Fig. 3, Fig. 3 is the schematic top plan view of flame stabilization ring in another embodiment.Flame stabilization ring 12 is provided with centre bore 13 and the equally distributed through hole 14 for the formation of stable flammule of a circle around centre bore 13, wherein, the wall of centre bore 13 is also provided with along the axially extended some grooves 15 of flame stabilization ring 12.
In an illustrated embodiment, each groove 15 is between two adjacent through holes 14, and each groove 15 has two relative planomural faces 16, two relative planomural faces 16 are connected by a cambered surface 17 in the bottom of groove 15, and the distance between two relative planomural faces 16 is reducing gradually on the direction bottom groove 15.Equally, the formation of groove 15 makes the wall area of centre bore 13 increase, and the area of the flame that the fuel combustion therefore sprayed from centre bore 13 is formed and contacting external air also can increase.Therefore, more air will be had and participate in burning, and improve the burning degree of fuel, effectively reduce noxious emission, the generation of such as carbon monoxide and nitrogen oxide.Meanwhile, due to sufficient combustion, the height of flame is also minimized, thus reduces light pollution, reduces the height of protective cover.
In sum, the invention provides a kind of efficient venturi burner, above-mentioned two embodiments all adopt and axially to extend thus the mode forming some grooves makes the wall area of centre bore increase along flame stabilization ring on the wall of centre bore, therefore, during fuel gas, flame can be made can to contact to make fuel gas Thorough combustion with more air.Effective reduction noxious emission, the generation of such as carbon monoxide and nitrogen oxide.Meanwhile, due to sufficient combustion, the height of flame is also minimized, thus reduces light pollution, reduces the height of protective cover.
Concept described herein may be embodied to other form when not departing from its spirit and characteristic.Disclosed specific embodiment should be regarded as exemplary instead of restrictive.Therefore, scope of the present invention is by appended claim, instead of determines according to these descriptions before.Any change in the letter and equivalency range of claim all should belong to the scope of these claims.
