Abstract
Methods and apparatus are provided for detection of leaks in boilers containing a temperature control liquid which is supplemented with feedwater and removed as blowdown and steam. The methods include measuring rates associated with the feedwater supplementation and blowdown and steam removal means, adding a tracer in a manner to ensure a non-constant concentration in the temperature control liquid, determining the concentration of the tracer in the blowdown, calculating the mass of the temperature control liquid, calculating the unaccounted for water rate and comparing this rate with zero to determine if a leak condition is present.
