Claim 7:
8. A system for detecting a fuel leak, the system comprising:
a gas turbine including an inlet section, a compressor, at least one combustor having a combustion liner that defines a combustion chamber in which combustion occurs, and a turbine section, wherein the combustor further includes a liquid fuel cartridge and a plurality of fuel nozzles; and
a particulate matter sensor positioned on at least one of the liquid fuel cartridge or a fuel nozzle of the plurality of fuel nozzles forward of the combustion chamber, the particulate matter sensor being configured to communicate a sensor output to a controller, the controller including a computing device in electronic communication with the particulate matter sensor, wherein the computing device is configured to:
monitor the sensor output from the particulate matter sensor, the sensor output comprising one of a fault state sensor output or a non-fault state sensor output; and
receive the fault state sensor output from the particulate matter sensor when a fuel leak is present within the combustor, wherein the fault state sensor output corresponds with a current ratio of the particulate matter sensor of between about 10% and about 100%.
