Abstract

PURPOSE: To prevent production of heat stress in a rotor and casing by controlling the amount of warming-up steam to gain approximately constant warming-up effectiveness with the warming-up steam temperature constantly kept higher than the inside surface temperature of the casing to a certain degree when the turbine casing is warmed up.
