Initial Conditions Data Immediately prior to initiating the turbine startup evolution, certain key data is collected and recorded. This data will be used to determine the heat soak times and the acceleration rate for rolling the turbine on steam. This data includes: • Main steam pressure at the turbine • Main steam temperature, at the HP turbine • Hot reheat steam temperature, at the IP turbine • First stage inner shell surface metal temperature • Reheat bowl inner surface metal temperature • Crossover chamber upper surface metal temperature, between IP exhaust and LP inlet Once this data has been recorded, the startup planning may begin.
