Abstract

A combustion control system for a turbine engine (100) is disclosed. The combustion control system includes a fuel injector (30) having a main fuel supply and pilot fuel supply coupled to a combustor (50) of the turbine engine. The combustion control system also includes a sensor (74) coupled to a transfer tube (68). The transfer tube is fluidly coupled to the combustor, and the sensor is configured to detect a pressure pulse (52) in the combustor. A semi- infinite coil (76) is also coupled to the transfer tube. The combustion control system also includes a controller (82) electrically connected to the sensor. The controller is configured to compare an amplitude of the pressure pulse within a frequency range to a threshold amplitude, and adjust the pilot fuel supply in response to the comparison.
