METHOD OF OPERATING A GAS TURBINE ENGINE AT A LOW POWER CONDITION
DRIVE
November 27, 2024
A system and method for operating a gas turbine engine (12A, 12B) are provided. The system and method remove fuel (46) from a fuel (46) manifold during a low-power mode of operation of the gas turbine engine (12A, 12B). The method includes supplying fuel (46) to a combustor (18A, 18B) of the gas turbine engine (12A, 12B) via a first manifold (31) and a second manifold (32) during a first mode of operation; stopping fuel (46) supply to the combustor (18A, 18B) via the second manifold (32) and continuing to supply fuel (46) to the combustor (18A, 18B) via the first manifold (31) during a second mode of operation; and, after stopping fuel (46) supply to the combustor (18A, 18B) via the second manifold (32), receiving the pressurized gas from the combustor (18A, 18B) into the second manifold (32) to purge fuel (46) from the second manifold (32).
