Abstract
A fuel delivery system for fuel nozzle staging includes a gas circuit and a fuel circuit. Each circuit includes a first manifold and a second manifold. The fuel delivery system delivers a first gas and a first fuel to a gas turbine engine during initial operation through the first manifold connected within each respective gas circuit. As the gas turbine engine reaches a predetermined operational speed, staging valves permit the fuel delivery system to also deliver the first gas and the first fuel to the gas turbine engine through the second manifold of each respective gas circuit.
