Abstract
The invention discloses a kind of gas combustion apparatus for controlling NO_x formation, which is made of combustion gas distribution tank, gas gun, rotational flow generator, backflow generator, ventilation hole, combustion chamber.Combustion gas uniformly flows into several gas guns after distribution tank, and is sent into combustion chamber by each gas gun.Combustion air generates rotation by being located at the rotational flow generator on the outside of lance outlet, and combustion gas is driven to inject in combustion chamber, is mixed and burned fuel and main air.Arrange that the indoor high-temperature flue gas volume that burns is drawn to the near axis of combustion chamber, reaches clean-burning purpose by backflow generator, the negative pressure generated after being flowed using gas at burner export center.Several ventilation holes opened up in backflow generator effectively prevent the high-temperature flue gas scaling loss backflow generator that volume sucks back.This combustion system feeds fuel and combustion air classification in combustion chamber, is conducive to the temperature for controlling fuel gas buring, achievees the purpose that reduce NO_x formation to the greatest extent.Simultaneously as ensuring that a certain amount of combustion gas and combustion air in the timely ignition of burner outlet near axis, stablize burning suitable for fuel gas with low heat value.
Description
Technical field
The present invention relates to fuel gas buring technical fields, relate more specifically to a kind of fuel gas buring for controlling NO_x formation
Device.
Background technique
Combustion gas has the advantages that environmental-friendly, dust and SO in the flue gas generated after burning as a kind of common fuel2
Concentration of emission is lower, and major pollutants are the N in the N element itself contained or air2It is raw with flue gas under the high temperature conditions
At nitrogen oxides (NOx).
In practical application, control fuel gas buring process generates the main means of NOx amount are as follows: reduces the oxygen at fuel gas buring initial stage
Amount suitably reduces ignition temperature.Common low nitrogen gas burner mostly uses flue gas recirculating technique, mixes in combustion air
Part low-temperature flue gas makes the O in flame2Concentration reduces, and ignition temperature is controlled, and then inhibits the production quantity of NOx.But the party
Method is complex, and flue gas recycled has certain corrosivity, and operational reliability is bad.
If combustion gas and air and mixed process can be organized effectively, the NOx generation amount during fuel gas buring can be reduced.
Summary of the invention
The invention proposes a kind of gas combustion apparatus for controlling NO_x formation, pass through the leading portion peace in burner
Multiple combustion heads are filled, form multiple small torches, and then achieve the purpose that effectively to control NOx generation amount.
To achieve the goals above, a kind of gas combustion apparatus controlling NO_x formation provided by the invention is by combustion gas
Distribution tank, gas gun, rotational flow generator, backflow generator, combustion chamber composition.In combustion gas distribution tank circle distribution multiple combustions
Gas spray gun, each gas gun outlet surrounding arrange rotational flow generator, fixed backflow generator among each gas gun, reflux hair
Several ventilation holes are opened up on raw device.
It is further described that combustion gas after distribution tank by evenly distributing into each gas gun, combustion air is sent out by eddy flow
Raw device exports in each gas gun and generates rotation, and combustion gas volume is inhaled, mixing.The combustion gas and periphery that each gas gun is sent out are revolved
The air turned enters combustion chamber mixed firinor fuel burning together, and under pressure, and it is further to form vortex at backflow generator rear portion
Mixing, overheavy firing.
The beneficial effects of the present invention are: combustion gas is sent into combustion chamber by multiple gas guns, the multiple spot of fuel is realized
It is sent into, disperses combustion, is conducive to the production quantity for controlling NOx.Each gas gun outlet is equipped with rotational flow generator, it is ensured that main combustion
Air is mixed into time, achievees the effect that stablize burning.
Detailed description of the invention
Invention invention is further described with reference to the accompanying drawings and detailed description.
Attached drawing is a kind of gas combustion apparatus schematic diagram for controlling NO_x formation.
In figure: 11, combustion gas distribution tank, 12, gas gun, 13, rotational flow generator, 14, backflow generator, 141, ventilation
Hole, 15, combustion chamber.
Specific embodiment
As shown in attached drawing, it is a kind of control NO_x formation gas combustion apparatus by combustion gas distribution tank 11, gas gun
12, rotational flow generator 13, backflow generator 14, ventilation hole 141, combustion chamber 15 form.
When burner is run, combustion gas is by combustion gas distribution tank 11 even into gas gun 12.Each burner is matched
Standby several gas guns 12, each gas gun 12 are evenly distributed in two reducing concentric circumferences, outlet and burner
Axis be a certain included angle, combustion gas can be made to disperse to project outward.Every gas gun 12 exports surrounding and fixes a combustion air
Rotational flow generator 13 can drive combustion gas rotational flow to form several independent small torches, and inject towards unacceptable direction
Combustion chamber 15.Backflow generator 14 is arranged in burner export center, is surrounded by each gas gun 12, can make each gas gun
The combustion air that 12 combustion gas projected and its surrounding project is after entering combustion chamber 15, and volume is drawn to the near axis of combustion chamber again,
Reach clean-burning purpose.
Several ventilation holes 141 opened up in backflow generator 14 effectively prevent the high-temperature flue gas scaling loss that volume sucks back and return
Flow-generator 14.
The above, embodiment is only that preferred embodiments of the present invention will be described, not to of the invention
Range is defined, and under the premise of not departing from the spirit of the technology of the present invention, this field engineers and technicians are to skill of the invention
The various changes and improvements that art scheme is made, should fall within the scope of protection determined by the claims of the present invention.
