Abstract
A fuel delivery system and method for operating a dual fuel and steam turbine engine that utilizes gas fuel at the engine start phase through a combination of gas and liquid fuel circuits. Gas fuel initially flows through the liquid fuel circuits to a dual fuel and steam nozzle. A boiler connected to the system generates steam, and the steam is supplied to the nozzle to raise the fuel pressure to an acceptable range. The gas fuel is injected into both the liquid and gas fuel circuits and the engine can then operate on either gas or liquid fuel, or any combination thereof.
