EEW Energy from Waste GmbH is building a new replacement for the existing energy from waste plant at the Stapelfeldsite, located northeast of Hamburg. The entire complex will consist of two individual plants, a thermal waste treatment plant for residual waste and a mono sewage sludge incineration plant. In the future, municipal waste, commercial waste similar to household waste and processed municipal waste will be thermally treated, electricity will be fed into the grid and district heating will be produced for the municipality of Stapelfeld and the Hanseatic City of Hamburg. Standardkessel Baumgarte received the order to supply the steam generator and the grate firing system for the new energy from waste plant.
For successful project implementation, Standardkessel Baumgarte relies on a steam generator with 3 vertical radiation passes and one horizontal convection pass, which also contains the first stage of the economizer. Sodium hydrogen carbonate is used as a reducing agent in the subsequent dry adsorption flue gas cleaning system. An SCR system for catalytic NOx reduction is also integrated into the RGR. To improve the overall boiler efficiency, a second economizer stage is connected downstream of the flue gas cleaning system to further cool the flue gases before they enter the stack.
