Description
Technical field
The present invention relates to the igniter of a kind of igniter, particularly a kind of boiler.
Background technology
Current, China is the country that recirculating fluidized bed (CFB) boiler generating set quantity is maximum in the world, total installation of generating capacity is maximum, with the fastest developing speed, and recirculating fluidized bed (CFB) boiler generating set has obtained using widely in China.
Recirculating fluidized bed (CFB) boiler generating set is to be generation driving force with the CFBB, when starting CFBB, the general bed oil gun combined launch mode of going to bed down that adopts, based on starting ignition under the bed, the ignition trigger system is the visual plant that is used for recirculating fluidized bed (CFB) boiler ignition start, low-load combustion-stabilizing, and the air channel start-up burner is mainly used in recirculating fluidized bed (CFB) boiler ignition under bed; Ignition under bed is owing to igniting heat utilization ratio height, and ignition trigger speed is fast, the burning hot distributed uniform of point etc. had a few, and extensively applies to the ignition trigger system of Large-scale CFB boiler.
But in the process of operation, often there is combustion instability in the air channel start-up burner, and the ignition air duct combustion is decreased, and start-up burner self fires problems such as damage, thereby has influenced the normal use of start-up burner.
Summary of the invention
Goal of the invention of the present invention is: at the problem of above-mentioned existence, provide a kind of simple in structure, air channel start-up burner easy and simple to handle, adopt this air channel start-up burner, make its flameholding in running, ignition air duct scaling loss and burner self scaling loss is few, also can be used as the not burner of preboiler simultaneously.
The technical solution used in the present invention is as follows:
Air channel of the present invention start-up burner, include one's intention as revealed in what one says road and outlet air channel, described inlet air channel and outlet air channel interconnect, and all link to each other with the heat primary air road, it is characterized in that: described outlet is provided with interior precombustion chamber in the air channel, is provided with at least one oil (gas) burner in the described interior precombustion chamber.
Since adopted said structure, preheating chamber structure in adopting, and be provided with at least one oil (gas) burner in the interior precombustion chamber, can guarantee the stable ignition and the burning of oil (gas) burner effectively.Air channel of the present invention start-up burner, when burning in the outer precombustion chamber, combustion product gases mixes with the air that main air duct enters, and uses place, one's intention as revealed in what one says road gas flow temperature and meets the requirements of temperature levels.Air channel of the present invention start-up burner, simple in structure, its flameholding in running easy and simple to handle, ignition air duct scaling loss and burner self scaling loss is few, also can be used as the not burner of preboiler simultaneously.
Air channel of the present invention start-up burner is connected with the burner airduct on described oil (gas) burner, is provided with the burner baffle plate in the described burner airduct, and described inlet is provided with the main air duct baffle plate in the air channel.
Owing to adopted said structure, can be by the size of the air quantity in the burner baffle controls burner airduct, thereby the burning size of control oil (gas) burner, can pass through the air quantity size in the main air duct baffle controls inlet air channel, thereby finally be controlled at the size of the burning in the outlet air channel.
Air channel of the present invention start-up burner, described oil (gas) burner is provided with stabilizer.
Owing to adopted said structure, on oil (gas) burner, adopt the less stabilizer of size, make flameholding in running; make combustion flame elongated, primary combustion zone is postponed till outer precombustion chamber, thus precombustion chamber in the protection; avoid burner self scaling loss, make the life-span longer.
Air channel of the present invention start-up burner, close oil (gas) burner one end circumferential arrangement of described interior precombustion chamber has a plurality of adherent wind nozzles, inside and outside the interior precombustion chamber of described adherent wind nozzle connection.
Owing to adopted said structure, at the root (promptly near oil (gas) burner one end) of interior precombustion chamber a plurality of adherent wind nozzles are set circumferentially, be communicated with interior precombustion chamber inside and outside; little air low speed is sent into interior precombustion chamber; form adherent wind,, avoid burner self scaling loss to protect interior precombustion chamber.
Air channel of the present invention start-up burner, the exterior circumferential of described interior precombustion chamber evenly is furnished with floor.
Owing to adopted said structure, precombustion chamber can be transmitted heat by floor in making, thereby makes good heat dissipation effect, and the structure of precombustion chamber is more surely leaned in making simultaneously, and precombustion chamber in the protection makes the life-span longer more.
Air channel of the present invention start-up burner, the air channel start-up burner is outer precombustion chamber between the outside of described interior precombustion chamber and the outlet air channel, is provided with refractory insulating layer on the inwall of described interior precombustion chamber and outer precombustion chamber.
Owing to adopted said structure, by refractory insulating layer is set, thereby avoid start-up burner self to be burnt out, guarantee long perfomance life.
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows:
1. air channel of the present invention start-up burner, simple in structure, its flameholding in running easy and simple to handle;
2. air channel of the present invention start-up burner, ignition air duct scaling loss and burner self scaling loss is few, also can be used as the not burner of preboiler simultaneously;
3. air channel of the present invention start-up burner, structure is surely leaned on, and is difficult for spontaneous combustion and damages, and long service life is beneficial to popularization.
