Leakage Detection Technologies for Air Cooled Condensers

This Request for Information (RFI) aims to gather insights on advanced leakage detection technologies applicable to air-cooled condensers (ACCs) at coal-fired power stations. The selected technology must be capable of detecting small air leaks, as minor defects can significantly impact turbine efficiency and operational costs. Given the complexities of ACC structures, which include high noise levels and limited access, the solution should provide reliable performance across large outdoor environments.

The RFI outlines specific requirements for the technology, including the ability to operate during normal conditions without requiring plant shutdowns. Respondents are expected to detail their experience with similar technologies, including the principles utilized for detection, equipment needed, and any drone-based inspection capabilities. The goal is to enhance the operational efficiency of Eskom's power stations by identifying and sealing leaks, which can lead to improved turbine performance and reduced fuel consumption.
