  • Gas turbine hot air injection power augmentation utilizing compressed stored air
    Patent number: 11976588
    Abstract: Gas turbine power plants augmented with an air injection system for hot air injection to augment power and are used to drive sensitive cogeneration processes are fitted with compressed air storage capability to more smoothly ramp on air injection in the event of sudden and unexpected interruption of the air injection system. Utilizing stored hot air injection prior to starting an air injection system significantly reduces the start-up time of the air injection system.
    Type: Grant

  • Gas turbine engine controls for minimizing combustion dynamics and emissions
    Patent number: 8504276
    Abstract: Embodiments for controlling a gas turbine engine to minimize combustion dynamics and emissions are disclosed. Methods and an apparatus are provided for controlling the gas turbine engine where a compressor inlet temperature is measured and a turbine reference temperature is calculated in real-time and utilized to determine the most-efficient fuel splits and operating conditions for each of the fuel circuits. The fuel flow for the fuel circuits are then adjusted according to the identified fuel split.

  • Transition duct assembly
    Patent number: 8322146
    Abstract: A transition duct assembly with a thermally free aft frame and mounting system for use in a gas turbine engine are disclosed. The aft frame is capable of adjusting to thermal gradients while the mounting system provides for at least transverse movement of the transition duct during engine assembly. The mounting system also provides a means for raising the natural frequency of the transition duct outside of the engine's dynamic excitation ranges.
