SOLID RECOVERED FUEL AS COAL SUBSTITUTE IN THE ELECTRICITY GENERATION SECTOR

ABSTRACT
According to the 1999/31 EC Directive, municipal solid waste should not be disposed for landfill from 2005. In this way, more environmental friendly waste management options are promoted towards the volume reduction and limitation of negative consequences. In this context, attention is focused on the utilization of solid recovered fuels derived from the waste treatment as coal substitute in large-scale power plants. Such activities are realized within an EU-funded project RECOFUEL, in which the solid recovered fuels co-combustion with brown coal is demonstrated in two commercial-scale PF-boilers at R WE Power's power plant site in Weisweiler, Germany. During testing the thermal share of solid recovered fuels in the overall thermal input was adjusted to some 2%, resulting into a feeding rate of about 2 x 12.5 tons per hour. NTUA-LSB in cooperation with IVD-University of Stuttgart, Germany, is responsible for the boiler measurements and the characterization of boilers operational behavior. Among the main activities are the technology transfer of co-combustion practice in the Balkan countries and the perspectives of its future application in the Greek region, with respect to the special characteristics of the Greek brown coal and municipal solid waste. Co-combustion tests of brown coal and solid recovered fuels, that have been taken place up to now, have been successfully performed and the strict European emission limits are kept. The waste quantities in Greece that can be utilized are estimated in 200,000 Mg/year while their utilization in existing thermal plants is expected to bring savings of 3% lignite use and avoidance of up to 200,000 Mg CO2 per year.
