Trace elements found in the fuel and in-furnace fine particles collected from 80MW BFB combusting solid recovered fuel

Abstract The main fine particle (d p 3 (g). It is proposed that the trace elements mentioned originate mainly from plastics and rubber where they are used as production additives, stabilisers, dyes, colorants and flame retardants. Cr, Cu and Zn may originate to a large extent from alloys and other metallic impurities. SEM-EDS analyses carried out for the SRF supports the postulated origin of the elements.
