Real Recovery Boiler Leaks and How to Detect Them, 1998 International Chemical Recovery Conference Proceedings
Water mass balance (WMB) data from real leaks in recovery boiler economizers, boiler bank, superheater, and floor tubes are analyzed to develop an understanding of leak size and growth rates as a function of location within the boiler. A second generation WMB leak detection system is presented which is designed to optimally detect leaks with these size and growth rate characteristics. The new method also corrects for the effect of potential interferences that may lead to false alarms.
