Application number is 201120229598.3, name is called in the patent document of " integrated igniter ", disclose a kind of by adpting flange, filter, three-way pipe, high temperature resistant compensating cable, blast pipe, burning shower nozzle, air register, double-venturi mixer-ejector, Gas Pipe, flameless burner, hurricane globe, and the igniter that forms of high-voltage arc ignitor, temperature thermocouple.Wherein the burn side of shower nozzle is equipped with blast pipe, the back of burning shower nozzle is connected with tracheae, be provided with filter and three-way pipe on the tracheae, tracheae is connected with fuel gas pipeline through adpting flange, and the high-voltage arc ignitor is connected with electronic lighter by high temperature resistant compensating cable.This igniter has not only that simple installation, support expense are low, long service life, do not need the characteristics such as maintenance for a long time, and power consumption is very low, reliability is high, the service life of its temperature thermocouple is also very long.
Application number is 99121137.5, and name is called in the patent document of " electrically controlled nozzle for plasma ignition of gas fuel ", discloses the integrated spray nozzle that the electromagnetic propulsion of a kind of gaseous fuel cylinder inner high voltage air feed and plasma igniter forces burning.Have simple in structurely, the life-span is long, and gaseous fuel circulation area is large, the advantage of fast response time, and functional reliability is high, to adapting to the change of energy resource structure, is used for indispensable people's the vehicles, and automobile is optimum structure for now.
Application number is in the patent document of US19930067652, discloses a kind of combustion chamber fire fuel device, comprises electromagnetism fuel atomization nozzle syringe and igniter.Syringe produces the main fuel that initial combustion process is lighted the fuel nozzle supply.Perhaps, in order to adapt to the igniter that is in the center, the main fuel nozzle comprises a plurality of electromagnetism fuel nozzles.In one embodiment, igniter is Laser Igniter.
Summary of the invention
The object of the present invention is to provide a kind of reliability of lighting a fire that can realize to reach fast the fuel gas eddy flow integrated igniter of stable state with guaranteeing to burn.
The object of the present invention is achieved like this:
Comprise mainly by the electrode that is positioned at the center, be positioned at the outer earth electrode of electrode, the plasma igniter that the dielectric between interior electrode and earth electrode and power connection consist of; Also comprise mainly by the swirler assembly housing, be installed on the fuel gas swirler assembly that the cyclone in the swirler assembly housing consists of; Described swirler assembly housing is annular, and a plurality of described cyclones are uniformly distributed in the annular swirler assembly housing, on the annular swirler assembly housing fuel gas air inlet are set; Described plasma igniter is arranged in annular swirler assembly housing, has a plurality of tangential admission apertures on the earth electrode; Connect to one by friction top between swirler assembly housing and the earth electrode.
The present invention can also comprise:
1, each cyclone is fixed in the annular swirler assembly housing by hollow nut.
2, the quantity of cyclone is 6-12.
The present invention proposes a kind of igniter with the combustion chamber and gaseous state fuel swirl assembly integral structure, air plasma igniter and fuel gas eddy flow assembly are carried out effective combination, utilize air plasma igniter supplying high temperature oxygen and active oxygen atom, the assurance fuel gas is lighted fast at head of combustion chamber; Dual cyclone effect by fuel gas cyclone and extraneous air cyclone forms stable recirculating zone at head of combustion chamber, and the flame of lighting is lighted in the recirculating zone rapidly, forms the point of safes burning things which may cause a fire disaster, guarantees that burning reaches stable state fast.
The air plasma igniter links to each other with the gaseous fuel swirler assembly by friction top, sealing gasket, hold-down ring etc., has both satisfied the seal of fuel system, also is convenient to dismounting and changes igniter.Its technical characterstic is the center that the air plasma igniter is positioned at fuel gas eddy flow assembly, i.e. fuel low regime, and the flame of lighting is difficult for being blown out, and makes igniting more reliable.The gaseous fuel cyclone on the swirler assembly housing, prevents that the fuel gas swirler assembly is loosening by the fixation hollow fastening nuts.
The present invention can realize the reliability of lighting a fire and guarantee that burning reaches stable state fast.The present invention is mainly used in gas-turbine combustion chamber, and the fuel gas eddy flow is coupled on the igniter, realizes fuel gas conflagration, by the reverse cyclonic action of fuel gas eddy flow assembly and extraneous air cyclone, guarantees the smooth combustion in the head recirculating zone.The present invention is fuel gas without interruption system, and high energy activation component and the fuel gas blending of adopting air plasma to produce guarantee its conflagration.The high energy activation component that adopts the air plasma igniter to produce realizes the moment burning, and controls igniting rigidity by the control size of current, guarantees that the flame of lighting just is positioned at the recirculating zone, thereby has realized reaching fast the purpose of smooth combustion.
