  • Publication number: 20200116024
    Abstract: A method of determining a remaining life in a component and a rotatable machine system are provided. The rotatable machine system includes a plurality of valves coupled in flow communication with a rotatable machine of the rotatable machine system, a plurality of sensors configured to receive operating parameters associated with the rotatable machine and the plurality of valves, and an online valve lifetime counter (OVLIC), including a processor communicatively coupled to the plurality of sensors. The OVLIC is configured to determine a trend of differential temperature across a body of a valve of the plurality of valves, convert the trend of differential temperature to a stress induced into the valve over time, and determine life remaining in the valve based on a total damage of the valve wherein the total damage is a function of creep damage and fatigue damage to the valve.

  • Patent number: 8684663
    Abstract: A steam turbine is provided having a relief groove which is arranged in the region of the equalizing piston and extends in the circumferential direction of the rotor. The relief groove, with regard to an inlet passage, is arranged in the axial upstream direction so that it is arranged on the rotor outside a region in which the steam flow enters the bladed flow path via the inlet passage. The relief groove, with regard to the first blade row, is arranged in a region in which the greatest thermal stresses can arise in the rotor. As an option, the relief groove has a cover for reducing vortex flows, and also devices for reducing heating of the groove or devices for active cooling. The steam turbine allows an increased number of risk-free running up and running down operations of the steam turbine with minimum detriment to the turbine performance.
