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

A dehumidifier assembly includes an extraction chamber coupled in flow communication with a sample air inlet, a sample air outlet, and a sample drip opening. The extraction chamber is configured to receive a sample air flow therethrough at substantially atmospheric pressure from the sample air inlet to the sample air outlet. The dehumidifier assembly also includes a conduit positioned within the extraction chamber. The conduit is coupled in flow communication with an environmental air inlet and an environmental air outlet, and is sealed with respect to the extraction chamber. The dehumidifier assembly further includes a circulator coupled to the environmental air outlet. The circulator is operable to create a negative pressure in the conduit, such that an environmental air flow is drawn through the environmental air inlet into the conduit. The conduit is configured to facilitate heat transfer from the sample air flow to the environmental air flow.

The present application provides a control valve actuator cooling system for providing a flow of cooling air to a control valve actuator. The control valve actuator cooling system may include a pressurized air source with the flow of cooling air, an air timing valve system, and a cooling air discharge port positioned about the control valve actuator such that the air timing valve system provides the flow of cooling air to the control valve actuator on an intermittent basis.

The present application provides a passive control valve actuator cooling system to provide a flow of cooling air to a control valve actuator used with a gas turbine engine. The passive control valve actuator cooling system may include a turbine enclosure with a negative pressure therein, a radiation shield with a number of radiation shield outlets and the control valve actuator positioned therein, and a cooling air line extending from outside of the turbine enclosure to the radiation shield such that the negative pressure within the turbine enclosure pulls the flow of cooling air into and through the radiation shield so as to cool the control valve actuator.
