The torch burning device of controlled auxiliary air
(1) technical field
The utility model relates to a kind of torch burning device, the torch burning device that particularly athletic meeting opening ceremony is lighted.
(2) background technology
The whole flame of existing torch burning device torch is to be combined to form by a plurality of burner flames, there is not the control of auxiliary air, an auxiliary air part is by ring center and circumferential weld central supply, because flame temperature height, ring center and circumferential weld center can produce pull out force upwards, make flame upwards be taper, the elegant degree of flame is relatively poor, has influenced the true to nature and attractive in appearance of flame.
(3) utility model content
The purpose of this utility model provides a kind of torch burning device of controlled auxiliary air, solves the required auxiliary air problem of torch burning of how controlling, and solves the relatively poor problem of the elegant property of flame of torch.
The technical solution of the utility model:
The mix flare burner of this controlled auxiliary air, its supply air line and full-automatic igniting device and flame monitoring apparatus, program control system connects, supply air line passes the pallet center from bottom to top, be communicated with at least one collector ring of Chang Minghuo combustion head in the pallet and concentric distribution, be evenly equipped with the burner of circular arrangement along collector ring, it is characterized in that: many burners longitudinally the medium position level be separated with the auxiliary air baffle plate of a circle, the diameter of auxiliary air baffle plate is greater than the external diameter of collector ring, have identical above the auxiliary air baffle plate with many burner diameters, the corresponding circular hole that distributes, each burner passes from the corresponding circular hole of auxiliary air baffle plate.
The thick 3-5mm of above-mentioned auxiliary air baffle plate.
The following supporting leg that connects of above-mentioned auxiliary air baffle plate, supporting leg is supported on the collector ring.
Said burner is an atmospheric burner.
The effect of auxiliary air baffle plate and principle: the torch burning device rearranges by a plurality of atmospheric burners are circular, is coupled together by the collector ring of a plurality of ring-types, forms the torch burning device of an integral body.Atmospheric burner at first the injection of burner nozzle next time air enter burner injector and combustion gas mixing, after the burning of head fire hole, by around the auxiliary air aftercombustion.The high more flame of primary air ratio is hard more, and the primary air amount is controlled by the burner air regulating board.After adding the auxiliary air baffle plate, the auxiliary air that has stoped ring center and circumferential weld, the pull out force of having avoided air to make progress, make the required auxiliary air of burner supply with by the periphery of integral combustion device, do not change primary air and do not produce black smoke situation under, it is more elegant, attractive in appearance to make that burner flame hardness reduces the flame of integral combustion device.
Compared with prior art, the utility model has the advantages that: can control the required auxiliary air of torch burning, thereby make the elegant property of flame of torch good, large and spectacular.Elegant, the true to nature and over-emitting black exhaust not of flame stabilization, make easy, safe and reliable, warp live wind and weather.The torch relay ceremony that is suitable for athletic meeting opening ceremony or large-scale group activity is used.

(5) specific embodiment
Referring to Fig. 1,2,3, the mix flare burner of controlled auxiliary air of the present utility model, its supply air line and full-automatic igniting device and flame monitoring apparatus, program control system connects, supply air line 5 passes pallet 8 centers from bottom to top, be communicated with at least one collector ring 4 of Chang Minghuo combustion head in the pallet 1 and concentric distribution, be evenly equipped with a plurality of atmospheric burners 2 of circular arrangement along collector ring, many burners longitudinally the medium position level be separated with the auxiliary air baffle plate 3 of a circle, the diameter of auxiliary air baffle plate is greater than the external diameter of collector ring, have identical above the auxiliary air baffle plate with many burner diameters, the corresponding circular hole 6 that distributes, each burner passes from the corresponding circular hole of auxiliary air baffle plate.
The thick 3-5mm of above-mentioned auxiliary air baffle plate.The following supporting leg 7 that connects of above-mentioned auxiliary air baffle plate, supporting leg is welded on the collector ring 4.The material of auxiliary air baffle plate 3: Q235-B or stainless steel.
Auxiliary air baffle plate 3 is diameter plectanes greater than burner collector ring external diameter, has the circular hole that passes for burner above.
