| 摘要 |
An apparatus and method for igniting a fuel and air mixture in a gas turbine engine combustor is disclosed. The apparatus comprises a plasma injector or ignitor (10) exhausting preferably an ammonia derived plasma (44) into the combustion chamber (16) of the turbine although any inorganic gas containing nitrogen and a predominance of hydrogen may be used. The ignitor comprises an annular conductive anode (24) forming a convergent nozzle therethrough and an elongated cathode (34) spaced from the anode by a gap. An electrical arc is generated between the cathode (34) and the anode (24). A high pressure flow of ammonia gas (40) is passed through the arc and through the nozzle to produce a plasma (44) therein rich in hydrogen atoms and ions to ignite the fuel and air mixture contained in the combustion chamber. |
