Description
Technical field
The present invention relates to field of combustion technology, more particularly to a kind of igniter burner and its ignition system.
Background technology
In combustion system, the presence or absence of flame sensing signal of igniter burner is to determine the main burner of annealing furnace
Whether gas valve opens the essential condition of burning.At present, the combustion gas of igniter burner and air are adopted
The mode of premixing, by detecting the ion current of flame judging the presence or absence of flame.Fig. 1
For the structural representation of the ignition system of prior art, Fig. 2 is the igniter burner of prior art
Structural representation.Referring to Fig. 1, the ignition system of prior art includes fuel gas pipeline 4, air hose
Road 5, blender 6 and the igniter burner 7 being connected with blender 6.Set on fuel gas pipeline 4 successively
It is equipped with the 3rd stop valve 401, air relief valve 402, electromagnetic valve 403 and the first locking-valve 404, air
The second locking-valve 501 is provided with pipeline 5, as shown in figure 1, combustion gas and air are respectively by Gas Pipe
After road 4 and air pipe line 5 enter the mixing of blender 6,7 ignition of igniter burner is entered back into.
Wherein, the system by 501 impulse of the second locking-valve from air pipe line 5 to air relief valve 402
The pressure carried out on fuel gas pipeline 4 is adjusted, so as to control the air-fuel ratio of the system.
As shown in Fig. 2 the igniter burner 7 of prior art includes the gaseous mixture of blowing air and combustion gas
The pipe 702 of body, ignitor 703 and shower nozzle 705, pipe 702 are respectively arranged at two ends with
Mixed gas import 701 and mixed gas outlet (not indicating in figure), mixed gas import 701
It is connected with blender 6, at mixed gas outlet, is provided with flame stabilization ring 704, shower nozzle 705 is connected to
At mixed gas outlet, ignitor 703 is arranged in pipe 702, and its end is extended surely
Flame ring 704 is placed in shower nozzle 705, circumferentially distributed on mixed gas Jing flame stabilization ring 704 and incline
The through hole for tiltedly arranging makes the radial ejection of mixed gas, so that after mixed gas ignition
The stable flame of a circle is formed, is beneficial to the detection of ion current signal.
But, at high operating temperatures, there is following both sides and lack in the igniter burner of prior art
Fall into：On the one hand, the temperature that mixed gas are preheated is higher, and as igniter burner is placed in stove
Length it is long, cause mixed gas also do not reach at the mixed gas outlet of pipe 702 just by
The burning-point of combustion gas is heated to, causes mixed gas advanced combustion, cause flame instability, tempering
And the adverse consequencess that ion current signal can't detect；On the other hand, condition of high temperature down-firing
The easily flexural deformation of electrode 703, between adding between the tube wall of ignitor 703 and pipe 702
Gap is less, and ignitor 703 easily encounters the tube wall of pipe 702, and contains in mixed gas
Various conductive elements, are easily short-circuited under electric field action, again result in mixed gas also not
Just burn at the mixed gas outlet for reaching pipe 702, do not only resulted in flame instability,
Tempering is susceptible to, and ion current detection device cannot also detect the presence of flame.
In order that flame status are stable, tempering prevented, and is able to detect that ion current signal,
Disadvantages described above can be overcome by improving mixed gas flow velocity, but can so cause the waste of the energy,
Igniter burner is also resulted in simultaneously shortens the life-span because over loading is burnt.
For the problems referred to above in the presence of prior art, there is provided a kind of new igniter burner and its
Ignition system has great importance.
