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 taper air feed is big to be adjusted 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 is 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 adopts porous circulus, 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
Scattered disk 3 partly overlaps, and 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.
The present invention operation principle be：Combustion air enters bellows 2, air adjustment baffle plate after air adjustment baffle plate 1
Folding angle can adjust in the range of 0-90 degree, so can make combustion-supporting air quantity according to the size of gas flow by than
Example is entered.Combustion air enters taper diffusion disc 3, trapezoidal point of the air duct of taper diffusion disc 3 after pressing 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 rear from the segmentation of taper diffusion disc 3 with gas fuel
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
Direction is substantially consistent with the angle of taper diffusion disc 3, 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, between the tip of ignition electrode 5 and gas nozzle 6 high-energy arc spark can be produced, as long as so combustion gas is sprayed through 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, in the presence of having flame, fire defector rod 7 will have and between ground
Electric current exist, during without flame, due to air it is non-conductive, would not be with the presence of electric current, by flame between fire defector rod 7 and ground
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 through taper diffusion
The secondary distribution of disk 3, it is ensured that when the air quantity of 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 adopted
Air adjustment baffle plate 1, gas nozzle 6 and taper diffusion disc 3 coordinate and are provided with taper diffusion disc 3 air of trapezoidal profile
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.
