Beschreibung
Zusammenfassung:	A heat transfer tube life estimating system (1) comprises a heat transfer tube temperature time change curve calibrating unit (7-1) for calibrating a heat transfer tube temperature time change curve representing change in a heat transfer tube temperature with time based on the heat transfer tube temperature as a temperature of an outer wall surface of the heat transfer tube and a heat transfer tube temperature transition predicting unit (9) for predicting transition in the heat transfer tube temperature based on the heat transfer tube temperature time change curve which has been calibrated. According to the system, the life of the heat transfer tube of the boiler can be estimated in real time during boiler operation.
