Leak detection in a subcritical boiler - ScienceDirect

Feb 25, 2021 · In this work, an attempt was made to detect and isolate leak in the subcritical boiler. Starting from the steady state analysis based on a mass balance of steam and feedwater flow around the steam drum, the threshold was defined for the leak detection. This threshold was then utilized as the upper control limit in the real time monitoring.
