In 2008, SEEGER ENGINEERING was commissioned by the ESWE BioEnergie GmbH to carry out the complete process engineering design of a biomass heat and power plant based on the fuel of waste wood, as well as the project management for the entire project. As part of the approval planning, it was also necessary to establish a project-specific development plan, which gained legal force in 2010. The construction site is located in Wiesbaden, south of the landfill site of ELW (Waste Management Company of the State Capital Wiesbaden) in the industrial area.
The biomass heat and power plant is designed as a steam heating power plant that provides heat to the district heating network of the ESWE Versorgungs AG throughout the year. The plant concept involves storing the biomass fuel, consisting of waste wood (categories A I to A IV), landscape maintenance wood, and wood residues, in a closed fuel storage hall. From there, the fuel is fed to the combustion process through a fuel sorting line. Combustion takes place in a horizontal water-tube boiler, and the flue gases are subsequently cleaned in a multi-stage flue gas cleaning system.
