ABSTRACT:
Leakage of water from a boiler water system wherein steam is generated in a boiler from feedwater fed to the boiler, and the concentration of impurities in the boiler water within the boiler is reduced by withdrawing fractions thereof as blowdown while admitting additional feedwater as boiler-water makeup, is determined. The boiler has a concentration cycle value, the concentration cycle value being the average value of the concentration of an inert component in the blowdown at steady state (C.sub.F) divided by the concentration of the inert component in the feedwater (C.sub.I). The concentration of the inert component in the boiler at steady state varies from a high concentration C.sub.H, having a value that is higher than C.sub.F, to a low concentration C.sub.L, having a value between the (C.sub.I) and the (C.sub.F), within a time period. The method comprises:
