    摘要: In a gas turbine engine that includes a compressor and a combustor, wherein the combustor includes a primary fuel injector within a fuel nozzle and a secondary fuel injector that is upstream of the fuel nozzle and configured to inject fuel into a flow annulus of the combustor, a method for detecting a flame holding condition about a fuel injector. The method may include the steps of: detecting an upstream pressure upstream of the secondary fuel injector; detecting a downstream pressure downstream of the secondary fuel injector; determining a measured pressure difference between the upstream pressure and the downstream pressure; and comparing the measured pressure difference to an expected pressure difference.

    摘要: A turbine to detect a flame holding event includes a combustion section to receive a fluid from a compressor, to heat the fluid by combusting a fuel to generate heat, and to output the heated fluid to a turbine section. The combustion section includes a combustor having a combustion chamber in which the fuel is combusted, and the combustion section having a sensor to sense a static pressure within the combustion chamber. A combustion control device detects a flame holding event in the combustion chamber based only on the sensed static pressure.

    摘要: An ignition system for a combustor includes an access port through a wall of the combustor and a laser outside the combustor and aligned with the access port to generate a beam along a path. A lens in the path of the beam focuses the beam at a focal point inside the combustor, and a shutter has a first position in the path and a second position out of the path. A method for igniting a combustor includes generating a beam along a path, focusing the beam to a focal point inside the combustor, and moving a shutter from a first position in the path to a second position outside of the path.
