Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Fig. 1-3 are referred to, a kind of big regulation of taper air feed is than burner, including air adjustment baffle plate 1, bellows 2, taper
Diffusion disc 3, burner inner liner 4, ignition electrode 5, gas nozzle 6 and fire defector rod 7, the air adjustment baffle plate 1 are hinged on bellows 2
Air inlet, gas nozzle 6 is arranged on the front end inside bellows 2 and the spout of gas nozzle 6 uses porous cyclic structure, cone
Shape diffusion disc 3 is arranged on the rear end inside bellows 2 and taper diffusion disc 3 is connected with gas nozzle 6, and fire defector rod 7 runs through
The air of trapezoidal profile is provided with gas nozzle 6 and fire defector rod 7 is extended in taper diffusion disc 3, taper diffusion disc 3
Passage, the aperture of air duct is in from the inside to the outside increase tendency, is expanded inside one end insertion bellows 2 of burner inner liner 4 and with taper
Dissipate disk 3 to partly overlap, ignition electrode 5 is arranged on the lower end of bellows 2 and ignition electrode 5 is connected with gas nozzle 6.Fire defector rod 7 is adopted
With ion bar, ignition electrode 5 is using electric heat ignition pin.Bellows 2 and burner inner liner 4 are made using stainless steel material.
Operation principle of the invention is：Combustion air is by entering bellows 2, air adjustment baffle plate after air adjustment baffle plate 1
Folding angle can be adjusted in the range of 0-90 degree, can so make combustion-supporting air quantity according to the size of gas flow by than
Example enters.Combustion air enters taper diffusion disc 3, trapezoidal point of the air duct of taper diffusion disc 3 after being pressed in bellows 2
Cloth, aperture is also gradually to increase from inside to outside.Air vent is started setting up from the root position of gas nozzle 6, in the flow path of fuel
On, air capacity is ascending segmentation supply.Air is segmented by being segmented with gas fuel afterwards from taper diffusion disc 3
Mixed combustion.Whole combustion process is completed in the range of taper diffusion disc 3 and burner inner liner 4.Fuel is on by natural gas line
Flow control valve distribution after enter gas nozzle 6, the spout of gas nozzle 6 is presented porous annular distribution, the outlet of spout
Angle of the direction substantially with taper diffusion disc 3 is consistent, and when such gas flow changes between size, fuel and combustion air are all
Burning can be sufficiently mixed.Ignition electrode 5 plays a part of pilot fuel of lighting a fire, and before fuel gas jet, ignition electrode 5 is by logical high pressure
Electricity, high-energy arc spark can be produced between the tip of ignition electrode 5 and gas nozzle 6, as long as so combustion gas is sprayed by electricity
Spark, combustion gas will be ignited.Fire defector rod 7 plays checking flame and whether there is, and in order to ensure safety, is continued in fuel
During supply, must ensure that fuel is sustained combustion, supply of otherwise burning can be forced to interrupt.Natural gas is in burning
During, faint ion stream is had in the flue gas of burning, there is the presence of ion stream, flame just has certain conductive work
With, as long as so adding certain voltage to fire defector rod 7, having in the presence of flame, fire defector rod 7 will have and between ground
Electric current is present, and during without flame, because air is non-conductive, exists there will be no electric current between fire defector rod 7 and ground, by flame
The electric current of test bar 7 is it may determine that flame whether there is.
Although the limited precision of air adjustment baffle plate 1, minimum wind supply quantity can not possibly reach 40：1, but spread by taper
The secondary distribution of disk 3, it is ensured that when the air quantity in the root of gas nozzle 6 is sufficiently small, unnecessary air can be in gas nozzle 6
Distal end supply.It is sufficiently small in the supply of gas flow, reach 40：When 1, flame just can be very short, only in root-burn, distal end
Air do not interfere with the stability of flame, and when gas flow is larger, such flame becomes can be elongated, in journey progressively with
Air mixed combustion, by the setting of this structure, the regulation of equipment is than can just accomplish sufficiently large.
The device is reasonable in design, and simple structure, fault rate is low, safety in utilization and good operation stability；The device is used
Air adjustment baffle plate 1, gas nozzle 6 and taper diffusion disc 3 coordinate and the air of trapezoidal profile are provided with taper diffusion disc 3
Passage, it is ensured that fuel is sufficiently mixed burning with combustion air, and the regulation ratio of device reaches 40:1, meet production equipment
Use demand；The device is additionally provided with fire defector rod 7, it can be determined that whether with the presence of flame, using effect is good.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be in other specific forms realized.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires to be limited rather than described above, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as the claim involved by limitation.
