摘要

PROBLEM TO BE SOLVED: To provide a method for replacing a stationary blade for a gas turbine, a stationary blade replacement assisting system, a stationary blade replacement assisting program for loading the stationary blade replacement assisting system on a computer and a computer readable record medium recording the stationary blade replacement assisting program, making operability and economy most efficient.;SOLUTION: In a method for replacing a stationary blade for a plurality of gas turbines provided with a stationary blade of which service life can be extended by a heat treatment, a new stationary blade is removed and the heat treatment is started when the blade approaches an end of a life thereof, other stationary blade of which heat treatment has been completed is attached instead of the removed stationary blade, the stationary blade is removed and other new stationary blade is attached when the stationary blade of which heat treatment has been completed approaches an end of an extended life, and timing of next stationary blade replacement is established after timing of completion of the heat treatment.;COPYRIGHT: (C)2005,JPO&NCIPI
