Claim 0:
1. A method of detecting a fuel leak within a combustor of a turbomachine, the combustor comprising a combustion liner defining a combustion chamber within which combustion occurs, the combustor further comprising a liquid fuel cartridge and a plurality of fuel nozzles, the method comprising:
monitoring, by a controller, a sensor output from 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 sensor output comprising one of a fault state sensor output or a non-fault state sensor output;
receiving, with the controller, 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%.
