| 摘要 |
This heat transfer tube life estimating system (1) comprises a heat transfer tube temperature change curve calibration means (7-1) for calibrating a heat transfer tube temperature-time change curve that indicates the change over time of the heat transfer tube temperature, which is the temperature of the outer wall surface of a heat transfer tube, on the basis of the heat transfer tube temperature, and a heat transfer tube temperature transition prediction means (9) for predicting the transition of the heat transfer pipe temperature on the basis of the calibrated heat transfer tube temperature-time change curve. By virtue of this system, the life of boiler heat transfer tubes can be estimated in real time during boiler operations. |
