State-owned power utility Eskom’s actions to rectify major boiler defects at its newly-built Medupi and Kusile power stations is improving the plants’ energy availability factor (EAF), in some cases almost doubling it from when the first boiler’s fires were lit.
The major boiler defects relate mainly to load losses as a result of issues with the boiler’s pulse jet fabric filter (PJFF) plant, gas air heaters and mills.
