Implementing optimal HPC and MPC flow part options into the thermal scheme of the K-540-23.5 turbine unit

Abstract

Consideration is given to the optimization peculiarities of the flow parts (FP) of the high-pressure cylinder (HPC) and the medium-pressure cylinder (MPC) of the K-540-23.5 turbine. The optimal options of the FPs of the HPC and MPC were imple-mented into the thermal scheme taking into account the effect of the underheating tem-perature of the feed water and steam parameters on the heaters during the steam bleed-offs.
