Abstract

The paper considers the problem of measurements of air amount in air-vapour mixture removed from condensers by steam ejectors. An efficient method for air inleakage rate measurements is proposed. It allows for accurate measurement and monitoring of air inleakage rate in the wide range from 0.5 to 150 kg/h of dry air. The results of such measureements may be easily implemented in diagnostic codes to evaluate the power losses resulting from the excess air influx into condensers. The monitoring systems based on the above method have been constructed and inplemented at the Turów power station for turbine units of 200 MW.
