Existing flexible processing, it is therefore an objective to realize scale, it is cost effective.
The course of work of the present embodiment is：
The 2 required combustion gas of separate type burner assembly by air inlet pipe arrival after ontrol valve assembly by dividing gas pedestal 1
Inside is realized after control distribution and is sprayed in center air nozzle 121, middle ring air nozzle 122, outer shroud air nozzle 123, driven
Air divides gas manifold 3 into corresponding injection.Center air nozzle 121 spray combustion gas after center injection divides gas manifold, into
Enter central burner, under the action of lighting a fire needle-discharging, realizes that central flame is lighted, to the middle ring outer ring fire that ignites.In lighting
Internal heat carries out heating to which order to security system works normally to putting out security personnel's total system inductive needle.Traditional infrared gas jamb
Only one or two ejector pipes, therefore in order to keep enough air introduction volumes, it is necessary to divide gas manifold 3 to increase injection and adds
Length could keep the entrance of auxiliary air enough, but the injection increased after lengthening divides gas manifold 3 in same stream pressure
In the case of, flow velocity can slow down jet length and can shorten, (principle, which refers to, uses flexible rubber hose waterproof, and bore is bigger, the flow velocity of water it is slower away from
From closer, if bore reduced, flow becomes effectively to penetrate immediately remoter), it is based on this principle, the present embodiment is improved to a plurality of
Air nozzle 12 and reduction injection divide 3 bore of gas manifold to be combined, and allow branched injection that gas manifold 3 is divided to force injection fed oxygen from air, real
It now only needs shorter injection stroke to can be achieved with entire burner fully to burn required oxygen, and keeps burner volume
It is smaller.
The combustion gas of middle ring outer shroud drives air after the ejection of 1 each air nozzle 12 of excessive gas pedestal under the action of injection principle
Divide gas manifold 3 bottom ejecting port into injection, divides in gas manifold 3 that twist ascending motion is tentatively mixed in injection,
When rising to injection and divide the diffusion horn mouth position on 3 top of gas manifold, there is diffusion and accelerate (megaphone amplification principle)
Reach independent mixed gas air deflector.Due to dividing the structure of gas manifold 3 using more air nozzles injection more than 12, combustion gas is into burner
Ontology 21 has multi beam combustion gas after mixing air cavity, if do not guided, must directly through Multi-hole infrared ray burner plate 5 air fuel gas
It is not thoroughly mixed and is just ignited, therefore burn and insufficient cause that the thermal efficiency is low and exhaust gas discharge is exceeded.Therefore must draw each
The top for penetrating point gas manifold 3 increases a secondary ramp type deflector, and guiding gas changes the direction of motion in cylinder
The mixed air cavity of body does shuttling movement, so that multiply combustion gas fully premixed after multi-turn mixing, to by more
It is released in the form of infrared light-wave after the fully premixed burning of the aperture realization direct injection of hole infrared combustion plate 5 a large amount of
Heat.
Since each injection divides gas manifold 3, vertical injection, the short design of injection stroke, combustion gas mixing logistics speed are pressed soon upwards
Power is big, and the high-temperature region for having independent mixed conductance flowing plate 4 that Multi-hole infrared ray burner plate 5 is isolated, therefore it is excessive to have prevented oven former pressure
In the disadvantage of jet mouth position burning after being ruptured with infrared combustion plate.
Due to the structure of traditional direct spray type hurner nozzle upward, it is susceptible to liquid, the aperture that sundries passes through burner plate
