ABSTRACT:
System and method for detecting and locating leaks in a steam condenser while the condenser is on-line and operating in its normal capacity. A tracer gas is mixed with water and introduced into the tubes of the condenser through an injector which can be positioned selectively to direct the gas toward different ones of the tubes. The occurrence of a leak is detected by monitoring for the presence of the tracer gas in the condensation chamber, and the location of the leak is determined from the position of the injector when the leak occurs.
