  • Cyclic load duty control for gas turbine
    Patent number: 4406117
    Abstract: A gas turbine control for ameliorating the adverse affects of cyclic load applications to both single-shaft and two-shaft gas turbines is disclosed. During cyclic load conditions, air flow is governed to control the output of the gas turbine while fuel flow is controlled to hold the firing or exhaust temperatures substantially constant.
    Type: Grant
    Filed: March 23, 1981
    Date of Patent: September 27, 1983
    Assignee: General Electric Company
    Inventors: William I. Rowen, Thomas E. Ekstrom, Donald L. Rexford
  • Cyclic load duty control for gas turbine
    Patent number: 4299088
    Abstract: A gas turbine control for ameliorating the adverse affects of cyclic load applications to both single-shaft and two-shaft gas turbines is disclosed. During cyclic load conditions, air flow is governed to control the output of the gas turbine while fuel flow is controlled to hold the firing or exhaust temperatures substantially constant. Regular fuel flow governing during non-cyclic loading conditions is also provided.
