摘要：The paper describes the analysis of a start-up process of supercritical steam turbines. The problem under the investigation is the decrease of thermal loads due to the designs that are specific to this type of machines. The analysis focuses on the main components - the rotor and the inner casing that operate under the highest level of the thermal loads. The analysis involves the determination of the temperature and the stress fields and the behavior in the response to transient loading (thermal elongations). The obtained results allow to compare various cases of the transient loading.
