RISNatural Cooling and Startup of Steam Turbines: Validity of the Over Conductivity Function
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The temperature drop during natural cooling and the way in which the steam turbine restarts have a major impact on the cyclic lifetime of critical parts and on the cyclic life of the whole machine. In order to ensure the ...
Thermal Modeling of an Intermediate Pressure Steam Turbine by Means of Conjugate Heat Transfer—Simulation and Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Today's power market asks for highly efficient turbines which can operate at a maximum flexibility, achieving a high lifetime and all of this on competitive product costs. In order to increase the plant cycle efficiency, ...
Experimental Investigation Into Thermal Behavior of Steam Turbine Components—Temperature Measurements With Optical Probes and Natural Cooling Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The steam turbine cooldown has a significant impact on the cyclic fatigue life. A lower initial metal temperature after standstill results in a higher temperature difference to be overcome during the next startup. Generally, ...
