摘要： Fuel injection nozzles used for reducing NOx in gas turbine engines has incorporated a variety of expensive and complicated techniques. For example, systems use schemes for introducing more air into the primary combustion zone, recirculating cooled exhaust products into the combustion zone and injecting water spray into the combustion zone. The present fuel injector (62, 166) reduces the formation of carbon monoxide, unburned hydrocarbons and nitrogen oxides within the combustion zone by providing a series of premixing chambers (110, 136, 160-180, 136, 160) being in serially aligned relationship one to another. During operation of the fuel injector (62, 166) the premixing chambers (110, 136, 160-180, 136, 160) have a liquid fluid, fuel or water, premixed with a gaseous fluid, air or fuel, respectively. The liquid fluid has a predetermined pressure and the gaseous fluid is introduced into the liquid fluid under a predetermined pressure greater than the predetermined pressure of the liquid fluid in a first mixing chamber (110, 180). The liquid fluid and the gaseous fluid is further mixed in the second mixing chamber (136) and air or an additional gaseous fluid is further mixed within the premixed liquid fluid and gaseous fluid in a third mixing chamber (160) prior to enter into the combustor (42) of a gas turbine engine (10).
