Abstract
This erosion estimation method is for estimating the degree of progress of erosion of a last-stage rotor blade of a steam turbine, the method including: a step for sampling supplied water containing a substance to be detected, which is included in the material constituting the last-stage rotor blade, from a water supply line that is connected to the steam turbine; a step for measuring the concentration of the substance to be detected in the sampled supplied water; and a step for estimating the degree of progress of erosion on the basis of the concentration thereof.
Claims6
An erosion estimation method for estimating a degree of progress of erosion of a final stage rotor blade of a steam turbine, the erosion estimation method comprising:
