Methods and apparatus are provided for detection of leaks in boilers (10) containing a temperature control liquid (12) which is supplemented with feedwater and removed as blowdown. The methods include measuring rates associated with the feedwater supplementation and blowdown (18), adding a tracer to the temperature control liquid, determining the change in rate of the feedwater supplementation, determining the mass of the temperature control liquid, deriving the change in concentration of the chemical tracer in the temperature control liquid, calculating the unaccounted for water rate and comparing this rate with zero to determine if a leak condition is present.

La présente invention concerne des techniques et un appareil pour la détection de fuites dans des chaudières (10) renfermant un liquide de régulation de la température (12) qui est complété par de l'eau d'alimentation et évacué par vidange. Les techniques utilisées consistent à: mesurer des taux en rapport avec l'appoint en eau d'alimentation et la vidange (18); ajouter un marqueur au liquide de régulation de la température; déterminer le changement de taux survenu dans l'eau d'alimentation; déterminer la masse du liquide de régulation de température; déduire les changements de concentration du marqueur chimique dans le liquide de régulation de température; calculer le taux d'eau non pris en compte et comparer ce taux à une valeur nulle pour déterminer l'éventuelle présence d'une fuite.
