The multiple pre-heater innovates by introducing the hot gas in the centre of the pre-heating vessel. The counter current flow, and centralized introduction of thermal energy improves heat transfer.

The pre-heater vessel is also designed as an integrated unit with the cold feed system. This ensures that the vessel maintains the required feed volume.

The development was driven by Tenova’s ongoing commitment to design technologies that reduce pyrometallurgical processes impact on industry.
