Abstract
A system is provided for detecting and controlling flashback and flame holding in a combustor of a gas turbine. The system includes at least one flame indicator disposed in a combustor and at least one detector disposed downstream from the flame indicator. The flame indicator may be configured to produce light when exposed to a flame and the detector may be configured to detect the light produced by the flame indicator.
Claims12
A system for detecting and controlling flashback and flame holding in a combustor of a gas turbine, the system comprising:
- at least one flame indicator disposed in a combustor of a gas turbine, said at least one flame indicator including at least one protective layer and at least one witness layer, said at least one protective layer configured to ablate in the presence of a flame so as to reveal said at least one witness layer, said at least one witness layer configured to produce light of a specific color when exposed to a flame;
- and
- at least one detector disposed downstream from said at least one flame indicator, said at least one detector configured to detect the light produced by said at least one flame indicator.
A gas turbine capable of detecting and controlling flashback and flame holding within a combustor, the gas turbine comprising:
- a compressor section configured to pressurize air flowing into a gas turbine;
- a combustor section disposed downstream of said compressor section and configured to receive the pressurized air discharged from said compressor section, said combustor section comprising a plurality of combustors configured to mix the pressurized air with fuel to form an air/fuel mixture and combust the air/fuel mixture;
- a turbine section disposed downstream of said combustor section, said turbine section configured to receive hot gases of combustion flowing from each of said plurality of combustors;
- at least one flame indicator disposed in at least one of said plurality of combustors, said at least one flame indicator including at least one protective layer and at least one witness layer, said at least one protective layer configured to ablate in the presence of a flame so as to reveal said at least one witness layer, said at least one witness layer configured to produce light of a specific color when exposed to a flame;
- and
- at least one detector disposed downstream from said at least one flame indicator, said at least one detector configured to detect the light produced by said at least one flame indicator.
