Комплексный подход оценки остаточного ресурса высокотемпературных элементов паровых турбин, отработавших парковый ресурс

Abstract

The complex approach to an estimation of a residual resource of high-temperature elements of steam turbines of the big capacity with definition of damages taking into account repair regenerative changes o fa design of the steam turbine inoperation and experimental researches of features of metal after 220 thousand hours of operation is offered. Are resulted settlement and experimental data of long durability of metal of rotors of average pressure and residual terms of operation of steam turbines of power units № 11, 13–15 which worked in different operational conditions.
