Flue Gas Heat Recovery at the Existing KVA Turgi Facility

The energy efficiency of the existing KVA Turgi facility is to be further improved through heat recovery from the flue gases of the two furnace lines 3 and 4 (OL3 and OL4). For this purpose, the installation and operation of an additional gas-water heat exchanger is planned, which will extract heat from the flue gas and transfer it to the district heating network. The installation and integration of this heat exchanger will require several retrofitting measures and modifications to the existing plant.

The planned flue gas heat recovery necessitates further adaptations, which must be taken into account both in the design of the new components to be supplied and in the modifications to the existing facility.
