Fuel nozzle with water injection

Apparatus for reducing smoke emissions exhausting from a gas turbine engine during water injection mode of operation, including a nozzle support having a generally cylindrically shaped body, a nozzle supported at one end thereof, an aperture in one end of said nozzle for injecting fuel centrally of said nozzle in a conical array, said conical array having an apex, a nozzle nut threadably supported on one end of said nozzle support, said nozzle nut having a generally conically shaped end portion surrounding a central opening concentric to said nozzle from which said apex of said conical array of fuel is formed, means for leading water through a plurality of drilled passages spaced about the circumference of said nozzle nut into a generally annularly shaped passageway formed between the inner diameter of said nozzle nut and the outer diameter of said nozzle and communicating with said central opening, an annular recess having a radially outwardly extending bore at one end of said annularly shaped passageway remote from said passages formed in the inner diameter of said nozzle nut for collecting water admitted into said annularly shaped passageway and also having a conically shaped wall radiating from a larger diameter at the extreme radial position of said bore to a smaller diameter adjacent said central opening, whereby the water collected in said recess is discharged about the entire circumference of said opening in a spray of small droplet size.
