The topic of the project is to enable the energetic use of biogenic residues and waste materials in compliance with current and future stricter limits. The exhaust cleaning process should be applied in the power range up to 5 MWth on combustion plants operated with biogenic residues and waste.


The aim of the project is to develop and test a cost-effective process for the combined reduction of fine dust, nitrogen oxides, HCl and SO2 as well as dioxins and furans. The reduction processes for individual pollutants existing in the power plant sector cannot be applied economically on decentralized biomass plants. Therefore the approach of the project is to combine different processes in one compact module, thus saving investment and operating costs in order to make the economical use in small and medium-sized plants possible.
