Dalkia takes up the challenge - it starts with a project preparation and cost calculation.
The project requires the construction of special equipment for heat recovery. Technical engineering, including detailed studies to optimise secondary heat, is required to complete the task. The operation and maintenance of the secondary energy recovery unit also deserves special attention. Dalkia undertakes to purchase hot water from ArcelorMittal's secondary energy recovery unit, with a saving of 92,000 MWh, and to supply hot water to Dunkirk's district heat network (maximum temperature 109°C) throughout the year. Dalkia takes on the challenge - it starts with design preparation and costing.
