摘要

PROBLEM TO BE SOLVED: To effectively utilize a used honeycomb structure by monitoring a honeycomb heat exchanger or a heat treating facility using the heat exchanger or evaluating the service life of the exchanger or facility by giving attention to the weight change of the honeycomb structure. SOLUTION: The weight change of the honeycomb structure used in a heat exchanger installed to the heat treating facility as a constituent member of a heat storage body is measured.
