Eltherm South Africa is responsible for the design and installation of the electrical heat tracing (EHT) system at the 100 MW Ilanga solar thermal power plant near Upington in the Northern Cape. Ilanga marks the second big concentrated solar power (CSP) project for the company this year; the installation of an EHT system is currently under way at the 100 MW Kathu Solar Park plant, also in the Northern Cape. As in Kathu, the company will deliver EHT to Ilanga’s thermal energy storage (TES), heat transfer fluid (HTF) and balance of the plant (BOP). Heat tracing is required at CSP plants to maintain temperature and prevent subsequent heat loss. The company will install most of the EHT at Ilanga’s TES facility which contains the plant’s molten salt storage. Temperature classes of T1 – T3 (450 to 200°C) will be maintained. This EHT system pre-heats empty pipes and equipment to maintain the right temperature throughout the plant’s storage process which also avoids solidification of fluids.
