  • Patent number: 6786049
    Abstract: A fuel supply control system for a gas turbine includes a plurality of solenoid valves. The solenoid valves are energized in a timing sequence with a phase relationship designed to achieve a desired fuel flow. In one example, one solenoid valve is associated with a primary portion of a fuel manifold while at least two other solenoids are associated with a secondary portion of the manifold. A controller that energizes the solenoids to achieve the desired fuel flow can receive feedback information regarding turbine performance to make adjustments to the solenoid operation to bring the turbine performance closer to a desired level.
