It is for shown in the drawings left and right；" inside and outside " refers to the inside and outside of the profile relative to each component itself, but the above-mentioned noun of locality is simultaneously
It is not used in the limitation present invention.
As depicted in figs. 1 and 2, the present invention provides a kind of liquid fuel igniting device, the igniter is interior to be formed a little
Ignitor 1 is equipped in fiery room A, igniting chamber A, wherein the liquid fuel igniting device includes that fuel sprays into pipe 2, flame
Bleed pipe 3 and condensate drain 4, fuel spray into pipe 2 and are stretched into igniting chamber A towards ignitor 1 to spray into air atomizing fuel, flame
Bleed pipe 3 is upwardly extended from igniting chamber A, and condensate drain 4 is extended downwardly from igniting chamber A, and air atomizing fuel is when lighting a fire unsuccessful
It is discharged by condensate drain 4 after wall can be coagulated in igniting chamber A.This liquid fuel igniting device can realize liquid fuel (example
Such as coal tar) direct-fire, will be specifically described below.
Aforesaid liquid fuel igniter has certain versatility, it is particularly suited in liquid-fuel burner.Liquid
Fuel burner generally comprises the main burner (not shown) that can spray the liquid fuel for igniting, liquid fuel igniting
The flame bleed pipe 3 of device extends towards main burner to light main burner.In this way, passing through the liquid in liquid fuel within igniter
Change fuel direct-fire and light main burner using individual liquid fuel igniting device, realizes to liquid fuel combustion
The novel ignition mode of device.
In the present invention, it is in order to realize the direct-fire to liquid fuel, and without auxiliary as total purport
The gaseous fuel of combustion and simply and easily put burner.For this purpose, being specifically designed small igniter room A, come in the igniting chamber
Directly light liquid fuel.Fuel sprays into pipe 2 and sprays into air atomizing fuel (the i.e. mixing of atomized fuel and air towards igniting chamber A
Object), the liquid fuel of mixing air is injected into micron-sized droplet by nozzle, and droplet forms injection stream in igniting chamber A inward turnings
Turn, is lighted a fire by ignitor 1 (such as high-voltage arc ignitor).If lighting a fire successfully, the body of high temperature, high pressure flame
Product can expand rapidly, and combustion flame will outward be sprayed by flame bleed pipe 3.Wherein, fuel sprays into 2 sustainable ejection air of pipe
Atomized fuel forms open fire so that flame bleed pipe 3 sprays Persistence flame, and open fire flame is sprayed onto the main burner of burner
On with ignite main burner ejection atomized liquid fuel realize the liquid of liquid-fuel burner hence into burning in burner
Change fuel ignition mode.Wherein, herein the focal point of nozzle and its structure etc. and non-present invention, and as common knowledge,

It sets.In other words, when this liquid fuel igniting device is installed in the burner, by the installation site adjusting to device, should make
The tie point of condensate drain 4 is in the lowest point in igniting chamber A.
Due to the burner hearth compared to burner, the volume of igniting chamber A is relatively small, and fuel sprays into what the primary igniting of pipe 2 sprayed
Liquid fuel amount is also relatively small, thus be not necessarily to excessively focus on igniting it is unsuccessful after liquid fuel accumulate and its caused by can
Can igniting the consequences such as fire.Thus after one or many igniting are unsuccessful, the liquid of accumulation is discharged in time by condensate drain 4
Fluid fuel can light a fire again.Certainly, the inert gases such as nitrogen can be also passed through, igniting chamber A is purged, realize inert environments
It lights a fire again afterwards.But when nonetheless, unsuccessful relative to the liquid fuel direct-fire of burner, the nitrogen of burner hearth is purged
Etc. subsequent processings, greatly simplify or reduce for workload, operation convenience and processing time etc..
Wherein, the volume of igniting chamber A can design according to actual needs with shape.In addition, fuel sprays into pipe 2 and condensate drain
4 cross section can be round, oval, rectangular etc., can also design according to actual needs.The volume of usual igniting chamber A with can
The spray volume of fuel is related when the failure ignition times of receiving are lighted a fire to single, and the volume of igniting chamber A should be greater than allowing unsuccessfully secondary
The sum of several fuel spray volume.Meanwhile compared to the burner hearth of burner, the volume of igniting chamber A should be designed as it is smaller, to avoid point
To the cumbersome processing of the removing of ejection liquid fuel etc. after fire failure.In this way, since the space in igniting chamber A is small, lighting a fire not
After success, purges, can be lighted a fire again even without using nitrogen, it is simple to operate.
It is further to note that the liquid fuel igniting device of the present invention is totally different from the dress of the igniting in engine
Set, from volume, shape, structure, function, purposes and operating status etc. it is all it is many-sided for, all with the igniting chamber of automobile engine
It is entirely different.The igniting chamber A of the present invention has condensate drain pipeline 4, can handle the liquid to precipitate when lighting a fire unsuccessful
Fuel needs the discharge accumulation fuel oil that stops when lighting a fire unsuccessful several times, could then light a fire again.Also, put igneous
Need to continue to spray into fuel after work(to form sustained combustion, until main burner is ignited, this has interval also different from engine
The instantaneous oil spout in ground has essential distinction with igniting, the two.
