A method of diluting one or more exhaust gases of a gas turbine engine system includes a number of steps. The gas turbine engine system includes a compressor, a combustor, and a turbine. The method includes determining if fuel is flowing to the combustor of the gas turbine engine system, detecting a flameout condition within the combustor, and releasing a dilution gas from one or more storage containers downstream of the turbine as a function of the detected the flameout condition.

Systems and methods for controlling an exhaust system

A system for coupling a first duct to a second duct configured for a gas flow with a gas turbine engine is disclosed. The system includes a first closed member and a second closed member. The first closed member is fixedly coupled to the first duct and defines an engagement surface. The second closed member is fixedly coupled to the second duct and defines a mating surface complementary to the engagement surface. The coupling of the first duct to the second duct includes one of the engagement surface and the mating surface complementarily receiving the other of the engagement surface and the mating surface such that a labyrinth interface is defined therebetween. Also, the first duct is sealed with respect to the second duct at the labyrinth interface such that a seepage of some of the gas flow through the labyrinth interface is restricted.

System for coupling ducts in gas turbine engines for power generation applications

Various embodiments include an offline leak detection system for a turbomachine fuel system. In some embodiments, the leak detection system includes: a fluid supply system fluidly connected to at least one fuel line of the turbomachine, the fluid supply system for delivering a non-flammable fluid to the combustor; a control system operably connected to the fluid supply system, the control system controlling a flow of the non-flammable fluid through the at least one fuel line, and controlling a pressure of the non-flammable fluid in the at least one fuel line to a pressure substantially equal to an operational fuel pressure of the turbomachine; and an optical monitor for determining a presence of the non-flammable fluid on an exterior of the at least one fuel line, the presence of the non-flammable fluid on the exterior of the at least one fuel line indicating a leak.
