Abstract: A fluid monitoring system includes a controller configured to determine that a value of at least one fluid property of a fluid is greater than a threshold value, and to control actuators to identify which fluid source has the fluid with the value of the at least one fluid property greater than the threshold value. Each actuator is configured to drive a respective crossover valve between a first position and a second position to direct the fluid from a respective first fluid source to a first manifold or a second manifold and to direct the fluid from a respective second fluid source to the first manifold or the second manifold. In addition, the first manifold is configured to direct the fluid to a first sensor assembly, and the second manifold is configured to direct the fluid to a second sensor assembly.

Abstract: A liquid injection apparatus for use with a compressor having a rotor shaft and a casing part is provided. The liquid injection apparatus includes at least one conduit and at least one nozzle coupled to the conduit(s). The liquid injection apparatus is panel-shaped and has a first panel segment, a second panel segment, and at least one of: a passage defined between the first panel segment and the second panel segment, the passage sized to receive at least one of the rotor shaft and the casing part; and a third panel segment positioned between the first panel segment and the second panel segment. The third panel segment is at least in part detachable from the first panel segment and/or the second panel segment for receiving at least one of the rotor shaft and the casing part between the first panel segment and the second panel segment.

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: A method of purging a combustor is provided. The method includes opening an isolation valve configured to regulate a flow rate of a fluid sent to at least one fuel nozzle of a combustor. The method also includes opening a control valve located upstream of the isolation valve after opening the isolation valve, wherein the isolation valve and the control valve are located within a fluid supply line.

Abstract: A method of flushing liquid fuel from valves and nozzles in a gas turbine is conducted via a mixing valve including flow passages for fuel and water. In the method, water is flowed through the flow passages, and the flow is interrupted for a period of no flow. This flow profile is repeated such that the water flow is pulsed through the flow passages.
