Abstract: A gas accumulation detection and ventilation system for a gas turbine enclosure includes a pipe array positioned adjacent a floor of the gas turbine enclosure and a ventilation assembly including a fan, an air flow inlet and an air flow outlet. The pipe array includes at least one pipe having at least one opening therein. The fan of the ventilation assembly directs an air flow sweep through the air flow inlet along the floor of the gas turbine enclosure. A hazardous gas sensor panel in communication with the pipe array and the ventilation assembly detects an accumulation level of turbine fuel gas in the gas turbine enclosure based on input from the pipe array and activates the ventilation assembly according to the detected accumulation level.

Abstract: A system includes a fluid distribution system. The fluid distribution system includes multiple spray rings disposed upstream of an inlet of a compressor. The multiple spray rings include a first spray ring disposed about an axis of the compressor in a first plane substantially perpendicular to the axis. The first spray ring includes a first set of nozzles disposed about the axis and configured to spray a first fluid flow toward the compressor inlet. The multiple spray rings further include a second spray ring disposed about the axis of the compressor in a second plane substantially perpendicular to the axis. The second spray ring includes a second set of nozzles disposed about the axis and configured to spray a second fluid flow toward the compressor inlet. The first plane is different than the second plane.

Abstract: A steam cycle system includes a heat recovery steam generator (HRSG) which receives exhaust gases, a steam turbine coupled to the HRSG which receives a first steam flow generated by the HRSG, and a condenser which condenses a second steam flow output by the steam turbine. The condenser includes a plurality of heat exchanger tubes, a fan, and a steam collection header. The system includes one or more sensors which measure one or more properties of the steam flow. The system includes a closed-loop controller communicatively coupled to the one or more sensors. The controller receives data from the one or more sensors, determines a flow rate of the second steam flow through the steam header using the one or more sensors, calculates whether the flow rate of the steam is within a threshold, and adjusts one or more operating parameters of the fan.
