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, and to adapting to the change of energy resource structure, for indispensable people's the vehicles, 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 initial combustion process and lights the main fuel of fuel nozzle supply.Or in order to adapt to the igniter in center, main fuel nozzle comprises multiple 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 that can realize igniting to reach fast the fuel gas eddy flow integrated igniter of stable state with ensureing to burn.
The object of the present invention is achieved like this:
Comprise mainly by the electrode that is positioned at center, be positioned at the earth electrode outside electrode, the plasma igniter that the dielectric between interior electrode and earth electrode and power connection form; Also comprise mainly by swirler assembly housing, be installed on the fuel gas swirler assembly that the cyclone in swirler assembly housing forms; Described swirler assembly housing is annular, and multiple described cyclones are uniformly distributed in annular swirler assembly housing, on annular swirler assembly housing, fuel gas air inlet are set; Described plasma igniter is arranged in annular swirler assembly housing, has multiple tangential admission apertures on earth electrode; Between swirler assembly housing and earth electrode, connect to one by friction top.
The present invention can also comprise:
1, each cyclone is fixed in annular swirler assembly housing by hollow nut.
2, the quantity of cyclone is 6-12.
The present invention proposes a kind of by the igniter of combustion chamber and gaseous state fuel swirl assembly integral structure, air plasma igniter and fuel gas eddy flow assembly are carried out to effective combination, utilize air plasma igniter supplying high temperature oxygen and active oxygen atom, guarantee fuel gas is lighted fast at head of combustion chamber; By the dual cyclone effect of fuel gas cyclone and extraneous air cyclone, form stable recirculating zone at head of combustion chamber, the flame of lighting is lighted in recirculating zone rapidly, forms point of safes burning things which may cause a fire disaster, ensures that burning reaches stable state fast.
Air plasma igniter is connected with gaseous fuel swirler assembly by friction top, sealing gasket, hold-down ring etc., has both met the seal of fuel system, is also convenient to dismounting and changes igniter.Its technical characterstic is the center that 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.Gaseous fuel cyclone on swirler assembly housing, prevents that fuel gas swirler assembly is loosening by fixation hollow fastening nuts.
The present invention can realize the reliability of igniting and ensure that burning reaches stable state fast.The present invention is mainly used in gas-turbine combustion chamber, and fuel gas eddy flow is coupled on igniter, realizes fuel gas conflagration, by the reverse cyclonic action of fuel gas eddy flow assembly and extraneous air cyclone, ensures the smooth combustion in head recirculating zone.The present invention is fuel gas system without interruption, and the high energy activation component and the fuel gas blending that adopt air plasma to produce ensure its conflagration.The high energy activation component that adopts air plasma igniter to produce realizes moment burning, and controls igniting rigidity by controlling size of current, ensures that the flame of lighting is just positioned at recirculating zone, thereby has realized the object that reaches fast smooth combustion.
