Improvement of the immission situation in residential areas by adapting the discharge conditions - replacement measures for chimney raising (Federal Environment Agency FKZ 3722 19 301 0)

In September 2023, Dr Cornelia Kalender, together with her colleagues Prof Bernd Leitl from the Meteorological Institute at the University of Hamburg and Dr Ulrich Vogt from the Institute of Combustion and Power Plant Technology at the University of Stuttgart, acquired an R&D project from the Federal Environment Agency.
The discharge of exhaust gases from small combustion plants in urban areas influences local and neighbourhood air quality. In the two-year project, various dispersion scenarios are being investigated in physical wind tunnel tests and with numerical flow simulation. In addition to different building shapes and arrangements, the release location on the roof due to the chimney position plays a role. Discharge conditions are specified and analysed in conjunction with the building circulation. A comprehensive specialist test and literature study will be carried out to investigate whether unfavourable discharge conditions can be compensated for and improved by technical measures at the incinerator.
