Power station’s gas cleaning systems upgraded

February 26th, 2015, Published in Articles: Energize


Eskom has awarded ACTOM John Thompson a multi-million rand contract to retrofit the gas-cleaning systems for three generation units at the utility’s Grootvlei power station near Balfour in Mpumalanga. The contract, due for completion in April 2016, involves replacing the electrostatic precipitators (ESPs) on Units 2, 3 and 4 with custom-designed pulse jet fabric filters. The project will complete the conversion of emission control from ESP plants to pulse jet fabric filter plants. The company fitted similar filters on Units 1, 5 and 6 at the power station as part of an earlier contract. The ESPs on Units 2, 3 and 4 were also refurbished during the power station’s return-to-service programme. However, due to dust loading at Grootvlei, the ESPs have proven no longer capable of meeting the stipulated emission control requirements, resulting in Eskom awarding the contract to retrofit Units 2, 3 and 4 with filters as had been done on Units 1, 5 and 6.
