Abstract: An integrated circulating water cooling system includes at least one load; an air cooling sub-system; a wet surface cooling sub-system; at least one temperature sensor; a control; and a coolant circulation sub-system for fluidly circulating coolant from the at least one load to the air cooling sub-system to the wet surface cooling sub-system and back to the at least one load. The control selectively operates the wet surface cooling sub-system and the air cooling sub-system based on at least one of temperature sensed in the water circulation sub-system; or sensed ambient temperature.

Abstract: A fire detection system for a gas turbine system including fire risk zones is provided. The system includes a pipe intake port proximate to each of the fire risk zones within a gas turbine system enclosure, and a manifold in fluid communication with the pipe intake port. A temperature sensor is positioned in the manifold upstream of a cooling system. The cooling system reduces a temperature of a gas flow in the manifold, allowing use of an aspirating smoke detector. An aspirating smoke detector, which is downstream of the cooling system, draws in the gas flow and detects smoke in the gas flow. A controller generates a first alarm in response to the temperature sensor detecting a temperature of the gas flow exceeding a temperature threshold, or a second alarm in response to the aspirating smoke detector detecting smoke in the gas flow.
