并给出了最佳温升率。
Abstract
Calculation and analysis of rotor's thermal stress field under operation mode of cold start-up in different temperature rise rate for 300 MW steam turbine unit have been carried out
obtaining variation relationship between the temperature rise rate and the thermal stress
as well as the influence of temperature rise rate upon the fatigue damage of rotor's life.And the optimal temperature rise rate has been also given.
