Abstract

A significant part of heat-mechanic equipment has already developed standard and extended resources. The scheduled repairs are reduced and overhaul periods are increased. Operation of power units in peak load with a large number of start-stops leads to their rapid wear and cracking in high temperature zones of elements of turbo-installations. Cracks in the rotors cause the possibility of further emergency operation. The economic situation at present cannot provide new equipment. There is a need to develop measures to increase the resource of a steam turbine.

The following measures are suggested to increase the resource of the steam turbine: change of operative conditions; preliminary heating of the rotor; removal of the damaged metal layer; change of the thermal circuit; reconstruction of thermal grooves
