CORROSION EVALUATION METHOD OF BOILER

摘要

PROBLEM TO BE SOLVED: To provide a corrosion evaluation method of a boiler, which can quickly and accurately perform corrosion evaluation even when combustion conditions are changed.SOLUTION: A corrosion evaluation method of a boiler includes: an attachment collection step S01 of collecting an attachment at a portion to be evaluated; a measurement step S02 of measuring the amount of at least sulfur and vanadium contained in the attachment; and a corrosion amount derivation step S03 of calculating the amount of corrosion at the portion to be evaluated on the basis of the temperature of the portion to be evaluated and a measurement result of the measurement step.SELECTED DRAWING: Figure 2
