Abstract: Systems and methods include an actuation system of turbomachinery includes a first actuator configured to control pitch of vanes of the turbomachinery and a first positioner configured to position the first actuator to control the pitch of the vanes. The actuation system also includes a second actuator configured to control the pitch of the vanes of the turbomachinery and a second positioner configured to position the second actuator to control the pitch. The actuation system also includes a controller system communicably coupled to the first and second positioners where the controller system is configured to drive the first positioner in an operation mode based at least in part on a set point. The controller system is also configured to set the second positioner in a diagnostic mode and obtain data from the first positioner and the second positioner where the data indicates operating conditions of the turbomachinery.

Abstract: A vaporization system for a liquid hydrocarbon for a combustion system of a gas turbine system is provided. The vaporization system includes: a vaporizer vessel; a pressure source providing a pressurized fluid to the vaporizer vessel; and a controller configured to control at least one control valve to: pre-elevate a pressure in the vaporizer vessel using the pressurized fluid from the pressure source prior to introduction of the liquid hydrocarbon to the vaporizer vessel to at least reduce vaporization of the liquid hydrocarbon in the vaporizer vessel, and control vaporization of the liquid hydrocarbon in the vaporizer vessel. A combustion system and kettle boiler system including aspects of the vaporization system are also disclosed.

Abstract: A vaporization system for a liquid hydrocarbon for a combustion system of a gas turbine system is provided. The vaporization system includes: a vaporizer vessel; a pressure source providing a pressurized fluid to the vaporizer vessel; and a controller configured to control at least one control valve to: pre-elevate a pressure in the vaporizer vessel using the pressurized fluid from the pressure source prior to introduction of the liquid hydrocarbon to the vaporizer vessel to at least reduce vaporization of the liquid hydrocarbon in the vaporizer vessel, and control vaporization of the liquid hydrocarbon in the vaporizer vessel. A combustion system and kettle boiler system including aspects of the vaporization system are also disclosed.

Abstract: Systems and methods include actuation system of turbomachinery that include an actuator configured to control pitch of vanes of the turbomachinery and a positioner configured to position the actuator to control the pitch. The actuation system also includes a controller system communicably coupled to the positioner. The controller system is configured to drive the positioner based at least in part on a set point of the turbomachinery and obtain data from the positioner indicating an amount of force used for a target pitch. Using the data, the controlling system derives an operating condition for the turbomachinery and controls the turbomachinery based at least in part on the operating condition of the turbomachinery.
