LIQUID FUEL LEAK DETECTION SYSTEM AND RELATED METHOD

Abstract:

A liquid fuel leak detection system for a gas turbine enclosure including a liquid fuel module is disclosed. The system includes a tube probe array positioned adjacent a floor of the gas turbine enclosure under the liquid fuel module, the tube probe array including at least one tube having at least one opening; and a first hazardous gas sensor panel in communication with the tube probe array, the hazardous gas sensor panel detecting a first accumulation level of turbine liquid fuel vapors in the gas turbine enclosure from the liquid fuel module based on input from the tube probe array, and creating an alarm in response to the detected first accumulation level exceeding a first predetermined amount. A pipe array under a fuel delivery system for detecting fuel leaks thereunder may also be provided.
