planned results:
The objecitve of the project is the demonstration of environmentally friendly, energetic sewage sludge utilisation in an innovative fluidization furnace for wastewater treatment plants in the classification size 4a with 10,000-50,000 population equivalents using the example of Hassfurt. Recent amendments to the Sewage Sludge Ordinance have resulted in an increased demand for mono-incineration capacities. As a decentralised process for sewage sludge incineration, the new technology can provide an important ecological contribution. The broad fuel band of the patented technology makes the energy supply more flexible by using additional biogenic residues in order to compensate fluctuations in fuel supply and prevent disrupting effects on the local energy system. Process-related advantages are offered by the optimization of emissions due to the establishment of different incineration zones for primary reduction of nitrogen oxide emissions. Planned investigations on the direct injection of additives should enable a reduction of pollutants in the ashes directly within the furnace and thus the production of a suitable educt for future phosphorus recycling. The technology has already been tested with sewage sludge in a prototype but has not yet been transferred into field operation.
Objectives of the project include the conception, implementation, commissioning, technical optimisation and long-term demonstration of the furnace as a modular incineration unit for sewage sludge. The results are used to establish this decentralised treatment process for sewage sludge and other biogenic residues, with complete coupling of the process heat into the infrastructure of the wastewater treatment plant, for sludge drying and heating of buildings. The goal is to achieve a selfsufficient energy supply for wastewater treatment plants by intelligent and flexible combination of sewage sludge incineration with the generation of electricity from sewer gas.
