Abstract:
Amyntaio's district heating company, DETEPA, implemented a significant bioenergy project in Western Macedonia by establishing a biomass-fired district heating plant with a capacity of 30 MWth. This project ensured a continued heat supply to the approximately 5,000 consumers, considering the complete nationwide phase-out of lignite. Initially, the plan was to solely utilize agricultural residues collected from local farmers as fuel. However, due to seasonal availability and unstable procurement costs, biomass only accounted for 58% of the delivered heat during the first year of operation (2020/2021), with the remainder being covered by lignite. Consequently, the integration of biomass led to a 38% increase in the selling price of produced heat. DETEPA aims to explore alternative fuel sources to replace the soon-to-be-phased-out lignite, emphasizing uninterrupted supply and low procurement costs as prerequisites. One potential option is Solid Recovered Fuel (SRF) derived from the organic fraction of Municipal Solid Waste (MSW) can serve as a long-term fuel source for DETEPA under favorable conditions. To assess the compatibility of SRF with the existing infrastructure and its compliance with the current environmental regulations, small-scale combustion tests were conducted at DETEPA's district heating plant. The results suggest that SRF and the plant's infrastructure largely meet the requirements of environmental regulations. However, attention should be given to achieving appropriate combustion conditions, while, extensive tests under a wider range of operating conditions and different SRF types are critical.
