Detection and quantification of leaks in heat exchanger circuits, by introduction of a fluorescent dye into the high pressure circuit and measurement of dye concentration over time in the second low pressure circuit

摘要

Method for determining the rate of contamination between two heat exchanger circuits and thus to quantify leak rates. According to the method a fluorescent dye is introduced into the first high-pressure circuit and the dye content in the clear water circulating in the second circuit is then measured using fluorimetry. The dye concentration in the second circuit can be monitored over time and as function of pressure conditions.
