초록 ▼

A secondary nozzle for a gas turbine includes an elongated, tubular nozzle body having an inlet end and an outlet end; a tubular core assembly having an outer diameter less than an interior diameter of the tubular nozzle body to thereby define a diffusion fuel passage between the core assembly and the tubular nozzle body extending to the outlet end, and a premix fuel passage through the core assembly extending to a pilot orifice at the outlet end; an air passage located along at least a portion of the tubular nozzle body and located radially between the diffusion and premix fuel passages; and, a plurality of gas injectors extending radially out of the elongated tubular nozzle body from the premix fuel passage.

대표청구항 ▼

A secondary nozzle for a gas turbine which includes primary and secondary combustion zones, the secondary nozzle comprising: an elongated, tubular nozzle body having an inlet end and an outlet end; a tubular core assembly having an outer diameter less than an interior diameter of said tubular nozzle body to thereby define a first axial fuel passage between said core assembly and said tubular nozzle body extending to at least one discharge orifice at said outlet end, and a second axial fuel passage through said core assembly extending to a pilot orifice at said outlet end; an air passage located along at least a portion of said tubular nozzle body and located radially between said first and second fuel passages; and, a plurality of gas injectors extending radially out of said elongated tubular nozzle body from said second fuel passage, upstream of said outlet ends.
