摘要

PROBLEM TO BE SOLVED: To provide a boiler heat transfer tube wall thickness estimation method capable of appropriately estimating the wall thickness of a boiler heat transfer tube in order to control the amount of corrosion of the boiler heat transfer tube in a power generation facility provided with a waste fuel combustion boiler. .. SOLUTION: In a boiler heat transfer tube wall thickness estimation method, in a power generation facility equipped with a waste fuel combustion boiler, (1) the wall thickness of the boiler heat transfer tube is measured, and (2) based on the measured wall thickness. Calculate the amount of wall loss at the measurement interval, (3) continuously measure the hydrogen chloride concentration in the combustion gas of the boiler, and (4) the integrated value of the hydrogen chloride concentration from the measured hydrogen chloride concentration and the boiler operating time. (5) Derived the correlation coefficient R between the reduced wall thickness of the boiler heat transfer tube and the integrated value of the hydrogen chloride concentration, and (6) derived the correlation coefficient R and the integrated value of the hydrogen chloride concentration. The wall thickness of the boiler heat transfer tube is estimated based on. [Selection diagram] Fig. 4
