Problems of carnotisation of steam turbine circuits

Abstract

The paper presents new concepts related to improvement of the efficiency of thermal circuits of steam turbines. Starting from a traditional C-R system, the efficiency losses of the circuit depending on the number of heat recovery exchangers in the system were indicated. Three different types of heat recovery regeneration exchangers that can be used in thermal circuits and their impact on the efficiency of the steam turbine system are presented. Further in the paper, the concept of the internal superheating and the possibilities of increasing efficiency in its use are presented.
