Tube leakage of steam boiler can decrease the whole efficiency of power plant cycle, and eventually cause an unscheduled shutdown. 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).

Key to the detection of tube leaks is Input/Loss' integration of system stoichiometrics with thermodynamics (i.e., boiler efficiency and system-wide mass/energy balances). Such integration starts with a combustion equation. Eq.(19B) defines all system stoichiometric terms, including the use of the b T term describing tube leakage.
