Description
Technical field
The utility model relates to ignition of the boiler technical fields, and in particular to a kind of circulating fluid bed boiler ignition
Device.
Background technique
Igniter is the important component of recirculating fluidized bed, the igniter of normal flow fluidized bed boiler, the work of igniter
Being used as principle is cooling point windburn from the channel among inner barrel and outer barrel, by the tube wall opening for being evenly arranged in inner cylinder axial direction
Middle to enter inner cylinder, then combination cooling flue-gas temperature, achievees the purpose that control igniting flue-gas temperature at 800 degree or so.But by
Point windburn in inner/outer tube channel often directly flows out from outlet because resistance is small, forms inner cylinder pressure and be higher than inner/outer tube channel,
And the point kerosene direction of motion is mutually perpendicular to point windburn direction, is generally aligned in the same plane oil gas with aperture with the contact point for putting windburn
Interior, the hot fume that oil gas burning generates is easy for entering inner/outer tube channel from some or certain several holes, finally because of hot fume
It flows through this channel for a long time, and the positions such as outer barrel is burnt and braise in soy sauce bad, cause the cigarette that leaks out, igniter is caused frequently to repair more
It changes, influence to light a fire and is safely operated, bring many puzzlements for owner.
Utility model content
For the problems of in the prior art, a kind of circulating fluid bed boiler igniting provided by the utility model
Burner may be implemented a kerosene and put the contact point Forward of windburn, and point windburn generates forward the hot fume that burning generates
Thrust, can effectively avoid hot fume and enter inner/outer tube channel, be conducive to improve equipment safety and service life.
To achieve the goals above, the technical solution adopted in the utility model is as follows：
A kind of circulating fluid bed boiler ignition burning device, including ignition air duct, the ignition air duct are connected with outer
Cylinder, the outer barrel is interior to be equipped with inner cylinder open at one end, and the inner cylinder open end and the outer barrel are far from the point
The one end in windburn road is tightly connected, and inner/outer tube channel, the inner cylinder are formed between the outer barrel inner wall and inner cylinder outer wall
Sealing end is equipped with and protrudes into the intracorporal atomizing lance of the inner cylinder and igniter, and the atomizing lance is matched with igniter,
The atomizing lance passes through the outer barrel and is connected with oil inlet pipe, and the sealing end of the inner cylinder is equipped with taper platform, the taper
Platform side is equipped with several equally distributed apertures being connected with the inner/outer tube channel, is equipped on the inside of the inner cylinder high-strength
Abrasion-proof and refractory pouring material layer.
Preferably, the hole shape is set as being similar to ellipse, and the aperture is set as even number, and the aperture is around described
Inner cylinder center line circumferentially array distribution.
Preferably, the inner cylinder open end is set as bell mouth shape, evacuates in time convenient for high-temperature flue gas.
Preferably, the high-strength wearable refractory casting thickness of feed layer is set as 60mm.
Preferably, it is equipped with several equally distributed columns between the inner cylinder and outer barrel to be connected, is conducive to enhance
The stability connected between the inner cylinder and outer barrel.
Preferably, the inner cylinder and outer barrel are all made of stainless steel material manufacture, and the stainless steel material is
1Cr18Ni9Ti。
The beneficial effects of the utility model are shown：
Inner cylinder sealing end is designed using taper platform in the utility model, by aperture design on taper platform side wall, is made out
There are certain angle between hole direction and inner wall axial direction, make a windburn that a kerosene and point may be implemented after aperture enters inner cylinder
Windburn inclination contact, make a kerosene and put windburn contact point move forward, pour in inner cylinder point windburn to igniting oil firing after
Hot fume forms forward thrust, can effectively avoid inner cylinder because hot fume caused by internal and external pressure difference is different leaks phenomenon, has
Conducive to extending the service life of ignition burning device, while in putting and can accelerating after aperture of the windburn through being obliquely installed enters inner cylinder
The flowing of gas in cylinder, can effectively reduce inner cylinder internal and external pressure difference.
