Leakage Detection of Steam Boiler Tube in Thermal Power

In this paper, we propose a leakage detection method for steam boiler tubes in thermal power plant (TPP) using principal component analysis and exponentially weighted moving average (EWMA). To determine the number of principal components, the cumulative percent variance technique is employed, and the Q statistic is used as the detection index.

Oct 08, 2002 · In this paper, a process model is proposed to describe the boiler tube leak problem. On the basis of this model and the boiler characteristics, a least-squares method with a forgetting factor is derived to detect boiler leakage. The analysis of leak estimation properties for the proposed method is given under certain conditions of boiler operation.
