ABSTRACT:
Fuel injection nozzles used for reducing NOx in gas turbine engines have 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 dual fuel injector reduces the formation of carbon monoxide, unburned hydrocarbons and nitrogen oxides within the combustion zone by providing a series of premixing chambers being in serially aligned relationship one to another. During operation of the dual fuel injector the premixing chambers have a liquid fluid and air or water and air being further mixed with additional air or a gaseous fluid and air. The liquid fluid and the gaseous fluid can be use simultaneously or individually depending on the availability of fluids.
