LIQUID FUEL STEAM PURGE SYSTEM FOR GAS TURBINE ENGINE

A system is provided with an ejector (18) having an outer wall (208) extending circumferentially about a flow path (203), wherein the outer wall (208) has a throat section (214) along the flow path (203), and a diverging section (216) downstream from the throat section (214) along the flow path (203). The ejector (18) includes a gas inlet (202) configured to supply a gas into the flow path (203), and a water inlet (206) configured to supply water into the flow path (203). The ejector (18) is configured to produce steam in response to mixing of the water and the gas along the flow path (203). The system also includes a controller (118) configured to control flows of the gas and the water to produce the steam for a steam purge of a liquid fuel circuit (24).
