  • METHOD OF CONTROLLING PURGE FLOW IN A GAS TURBOMACHINE AND A TURBOMACHINE CONTROL SYSTEM
    Publication number: 20150159561
    Abstract: A method of controlling purge flow in a gas turbomachine system includes detecting a fault condition in the gas turbomachine system, initiating a shutdown of the gas turbomachine system, introducing a purge flow into a gas turbine portion of the gas turbomachine system, categorizing the fault condition as one of a category one fault and a category two fault, and validating the purge flow if the fault condition is a category one fault and invalidating the purge flow if the fault condition is a category two fault.

  • Turbine casing
    Patent number: 8777566
    Abstract: A casing includes an inner shell and an outer shell that surrounds the inner shell and comprises a plurality of inflection points. An annular flange is between the inner shell and the outer shell, and a plurality of joints attach the inner shell to the annular flange. A connector is between the annular flange and the outer shell at each of the plurality of inflection points. A method for assembling a casing includes joining a plurality of curved sections to one another to generally define an arcuate inner shell and surrounding the arcuate inner shell with an outer shell. The method further includes attaching the arcuate inner shell to an annular flange at first attachment points and connecting the annular flange to the outer shell at second attachment points spaced approximately equidistantly from the first attachment points.

  • Systems and methods of reducing heat loss from a gas turbine during shutdown
    Patent number: 8210801
    Abstract: A method operates a gas turbine that includes a compressor section, a turbine section and an extraction cooling system. The method includes monitoring an operation of the gas turbine, directing a cooling air flow through the extraction cooling system from the compressor section to the turbine section in response to normal operation of the gas turbine, and directing a warming air flow through the extraction cooling system to the compressor section and the turbine section in response to shutdown of the gas turbine.
