ABSTRACT:
Methods and apparatus are provided for using tracers to monitor industrial process equipment to which liquid is added and from which liquid is removed. In preferred embodiments, the methods are directed to detecting water leakage in a boiler in which an aqueous temperature control liquid is supplemented with feedwater at a known or unknown rate and is removed as blowdown, sootblower steam and steam at a known rate. The methods include determining the blowdown removal rate, adding a tracer to the temperature control liquid at a rate that is directly proportional to the blowdown removal rate, analyzing the blowdown to determine the measured concentration of tracer contained therein, deriving an expected concentration of tracer in the blowdown, comparing the measured and expected concentrations to detect excessive variance between them, and also determining the rate of feedwater supplementation, monitoring the rate of blowdown, sootblower steam and steam removal, and comparing the difference between the supplementation and removal to detect excessive variation between them.
