Управление ресурсом корпусных деталей паровых турбин

Abstract

Computational investigations of the resource characteristics of the high temperature casing elements of a steam turbine allows for the control of the residual resource. The control over the residual resource is exercised by changing operation modes, improving thermal circuit, removal of the damaged metal, changing the structure during the equipment overhaul, etc. The supply of hot steam from neighboring energy blocks to the front end seal of HPC and IPC of the steam turbine K-200-130 LMZ will result in the improvement of the resource characteristics of high and intermediate pressure casings by more than 50 %.
