Abstract
Frequent and rapid startup-shutdown cycles in solar thermal power turbines accelerate the consumption of their service life,making the operational safety of high-temperature rotor components particularly critical.Using the finite element method,this study analyzes the transient temperature and stress fields of the intermediate and low-pressure rotors during daily startup process.The Manson-Coffin equation is employed to predict the rotor's fatigue life,and the calculation results indicate that for a warm startup following a 12-hour shutdown,the single startup-shutdown cycle results in a rotor life consumption of 0.002%.Furthermore,by setting the temperature rise rates of reheat steam to 1.5℃/min and 2.2℃/min respectively and comparing the corresponding fatigue life parameters,it is determined that the former rate offers a balance between fatigue life and economy.This rate ensures the operational safety of the rotor while meeting the requirements for the rapid and frequent startup-shutdown cycles of solar thermal power turbines.The research findings can provide data support for the life assessment of solar thermal power turbine rotors during warm startup.关键词
