UP-TO-DATE CONDITION AND PERSPECTIVE SOLUTIONS FOR IMPROVEMENT OF HEAT EXPANSION SYSTEMS OF STEAM TURBINES

Abstract

Technical and organizational problems, connected with functioning normalization for heat expansion systems (HES) of steam turbines are considered. The approved technical decisions for a range of reasons of bearing cases moving difficulties are noticed. It is presented, that the complex approach for solutions of HES stable operating and exposure resistance is necessary at the new turbines design.
