Abstract: A leak detection system is provided with a first window configured to mount at a first opening in a first wall portion in an enclosure (e.g., for a gas turbine engine or other equipment in a power plant). The leak detection system includes a leak sensor configured to transmit a beam through the first window and an interior of the enclosure to obtain sensor feedback. The leak detection system includes a controller configured to evaluate the sensor feedback to monitor for a leak of a hazardous fluid in the enclosure.

Abstract: A system includes a fluid distribution system. The fluid distribution system includes a first water wash nozzle configured to spray a wash fluid into an intake flow received through a bell mouth of a compressor during operation of the compressor in a water wash mode. The first water wash nozzle includes a first inlet end coupled to the bell mouth of the compressor, a first tip disposed opposite the first inlet end, and a first body of the first water wash nozzle extending from the first inlet end to the first tip toward an axis of the compressor. The first water was nozzle further includes a first outlet disposed at the first tip and configured to spray a first portion of the wash fluid into the intake flow during operation of the compressor in the water wash mode and a second outlet disposed along the first body and configured to spray a second portion of the wash fluid into the intake flow during operation of the compressor in the water wash mode.

Abstract: An inlet system for a gas turbine includes an inlet air duct; a silencer disposed in the inlet air duct, the silencer including a plurality of panels with spaces between the panels; and a conduit with orifices disposed to inject inlet bleed heat into each of the spaces. A method of conditioning inlet air for a gas turbine includes flowing air through spaces between panels of a silencer in an inlet air duct of the gas turbine, and injecting inlet bleed heat through orifices and into each of the spaces.
