Results

Final report only available in german.

Key results:

  1. The incineration of biogenic residues and waste materials causes increased emissions of dust, NOx, SO2 and HCl compared to wood fuel.
  2. In order to comply with statutory emission limit values, waste systems require a downstream exhaust gas cleaning system, which enables a reduction of all relevant groups of pollutants.
  3. The combination of fabric filter, SCR catalyst and dry sorption enables a cost- and space-saving reduction in emissions in decentralized systems that use biogenic residues.
  4. The exhaust gas temperatures, which are limited for reasons of efficiency, limit the reduction performance of the SCR catalytic converters used to a maximum of 50%. In order to achieve higher reduction rates, it is necessary to develop new types of SCR catalytic converters for the low temperature range.
  5. The pre-coating of the fabric filter enables acidic exhaust gas components to be reduced. During implementation in practice, however, careful attention must be paid to compliance with the necessary operating parameters to make sure the precoating can achieve the desired reduction performance.

Topic

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.

Aim

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.
