Description

One is pressed pulse firing burner

Technical field

This utility model relates to natural gas or liquefied gas burner technology field, is specifically related in one press pulse firing burner.

Background technology

At present, medium-pressure burner or the commercial oven tool that is commonly called as typically in restaurant or dining room for cook, the burner of this type is in actual use, need direct-fire or the ever-burning flame main flame burning things which may cause a fire disaster of offer is provided, or use single combination flame projection type igniter fire, when single igniting is unsuccessful or combustion gas is not in place, it is impossible to stop igniting when forming flame, it may occur that gas leakage；Use these methods above-mentioned igniting to there is potential safety hazard, and easily gas leakage causes breaking out of fire, give and use unit to cause security incident.

Summary of the invention

In order to overcome above-mentioned deficiency, in order to solve the problems referred to above, the purpose of this utility model is to provide in one presses pulse firing burner, and this burner can be lighted a fire by continuous impulse, it is ensured that igniting is accurately.

By the one that this purpose designs is pressed pulse firing burner, including burner, in burner, it is provided with blast tube, its architectural feature is, burner upper end is provided with annular split fire head, and inside and outside two ring edges of split fire head are laid with several venthole respectively, and the center of split fire head is provided with firing porcelain needle.

Described burner rear end is provided with injection nozzle carrier, and injection nozzle carrier rear end is threaded secondary air nozzle, and secondary air nozzle connects air inlet pipe, and the air inlet pipe other end connects burnt gas valve, and firing porcelain needle connects pulse ignition switch by pulse firing line.

Described air inlet pipe, burnt gas valve, pulse firing line, pulse ignition switch upper end are equipped with shell.

Described venthole is positioned at the top of split fire head.

Described burner upper end has been bolted stove basin.

This utility model, by above-mentioned technological improvement, has the advantages that

This burner uses combustion gas separately positioned with pulse firing, the mode of continuous impulse formula igniting, it is ensured that the accuracy of igniting, and flame not firing pulse lighter does not stops, simple in construction, and igniting is reliable, because lighting a fire not, security incident will not occur；Split fire head disclosure satisfy that secondary mixes oxygen, increases oxygen content, sufficient purpose of burning.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model one embodiment burner and furnace shell.

Fig. 2 is the structural representation of burner in this utility model one embodiment.

In figure: 1 is stove basin, 2 is distributor, and 3 is firing porcelain needle, and 4 is injection nozzle carrier, and 5 is secondary air nozzle, and 6 is pulse firing line, and 7 is air inlet pipe, and 8 is burnt gas valve, and 9 is pulse ignition switch, and 10 is shell.

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment the invention will be further described.

See Fig. 1-Fig. 2, pulse firing burner is pressed in Ben, including burner 11, being provided with blast tube in burner 11, burner upper end is provided with annular split fire head 2, and inside and outside two ring edges of split fire head 2 are laid with several venthole respectively, meet secondary and mix oxygen, increasing oxygen content, burn sufficient technique effect, and the center of split fire head 2 is provided with firing porcelain needle 3.

Burner 11 rear end is provided with injection nozzle carrier 4, and injection nozzle carrier 4 rear end is threaded secondary air nozzle 5, and secondary air nozzle 5 connects air inlet pipe 7, and air inlet pipe 7 other end connects burnt gas valve 8, and firing porcelain needle 3 connects pulse ignition switch 9 by pulse firing line 6.

Air inlet pipe 7, burnt gas valve 8, pulse firing line 6, pulse ignition switch 9 upper end are equipped with shell 10, play the protected effect of heat insulation, oil removal etc..

Venthole is positioned at the top of split fire head 2, preferably meets secondary and mixes oxygen, increases oxygen content, and burn sufficient technique effect.

Burner 11 upper end has been bolted stove basin 1.

During use, burnt gas valve 6 connects natural gas line or liquid gas storage tank, open burnt gas valve 6 natural gas or liquefied gas and enter burner 11 via air inlet pipe 8, sprayed by split fire head 2 after wind distributing hole 3 air distribution, pulse ignition switch 7 is opened, carry sparking pulse continuously to be lighted by fire to pulse firing porcelain pin 10, after flame stabilization, close pulse ignition switch 7.

Above disclosed only preferred embodiment of the present utility model, rather than limit claims of the present utility model with this, according to the equivalent variations made in this utility model protection domain, still belong to the scope that this utility model is protected.
