Abstract: Systems and methods of detecting a fuel leak are provided. A method of detecting a fuel leak within a turbomachine combustor includes a step of monitoring, by a controller, a sensor output from a particulate matter sensor positioned on a component within the combustor. The sensor output includes one of a fault state sensor output or a non-fault state sensor output. The method further includes receiving, with the controller, the fault state sensor output from the particulate matter sensor when a fuel leak is present within the combustor.

Abstract: A combustor includes an end cap that extends radially across at least a portion of the combustor. The end cap includes an upstream surface axially separated from a downstream surface. A plurality of tubes extend from the upstream surface through the downstream surface of the end cap to provide fluid communication through the end cap. Each tube in a first set of the plurality of tubes has an inlet proximate to the upstream surface and an outlet downstream from the downstream surface. Each outlet has a first portion that extends a different axial distance from the inlet than a second portion.

Abstract: A method for selectively operating a combustor head end assembly is provided. The combustor head end assembly includes a plurality of bundled tube fuel nozzles. The method includes opening a first fuel circuit of a plurality of fuel circuits. The first fuel circuit of the plurality of fuel circuits is fluidly coupled to a first nozzle group, and the first nozzle group includes one bundled tube fuel nozzle of the plurality of bundled tube fuel nozzles. The method further includes adjusting an airflow received by the plurality of bundled tube fuel nozzles in response to opening the first fuel circuit of the plurality of fuel circuits. The airflow is adjusted based on an emissions output requirement corresponding with the first nozzle group. The method also includes firing the first nozzle group.
