Planned results:
In addition to major biobased solid fuels such as residual wood from forestry or landscape conservation, interest in residual biomass and biogenic waste materials for thermal utilization to substitute higher quality wood fuel is increasing. From the perspective of a resource-efficient biobased economy, the priority is to identify the material flows at the end of the material-use cascade and to utilize them in the most resource efficient manner (here secondary biogenic residual and waste materials). High-quality energy recovery of these materials in biomass combustion offers such a recovery route, because it contributes to resource efficiency and increases the input flexibility of combustion plants.
Overall, the project aims to expand the fuel input spectrum of biomass cogeneration plants. For this purpose, suitable treatment strategies are developed and adapted for screenings from biowaste treatment and specific residue streams from grassland management under technical, ecological and economic aspects. The typical problem of slagging in connection with the thermal utilization of biogenic residues and waste materials is a major focus of the project. In particular, the ash melting behaviour of the different fuels and fuel mixtures is thoroughly investigated to enable the use of bio-residual fuels in a controlled and efficient way without causing increased plant damage. One major project outcome will be a practice guide and recommendations, including legal and technical aspects, to promote the use of biogenic residual and waste materials for co-incineration in biomass cogeneration plants.
