THE TASK
Shell Deutschland Oil GmbH operates a power plant at the Wesseling location for supplying the adjacent refinery with electricity and process steam. To fulfil the new environmental guidelines, two old boilers have been set out of operation and the installation of two new boilers has been planned. Standardkessel Baumgarte was entrusted with the task of constructing the new boilers No. 7 and No. 8 in order to secure the energy supply to the refinery and to dispose the production residues. It was particularly important for Shell to meet its energy requirements from its own production residues in order to save primary fuels.
THE SOLUTION
The new boiler No. 7 is mounted on the existing foundations of an old boiler house. The flue gas desulphurisation plant was already provided by the customer for boiler No. 6 and designed for a later extension. Within the scope of the construction of the new building, the new boiler was connected to the existing flue gas desulphurisation plant. The new boiler is designed in vertical construction and operates in natural circulation. The burner system
