✦ Synopsis

elements retained by the ash have been reported: relative enrichment in the "sinter-ash" was calculated by comparing with "bottom ash". Mercury was almost completely volatilized from all fuels, as was selenium for all except wood-bark. Chromium, manganese and thallium were partially volatilized and nickel mostly retained in all samples. The behaviour of beryllium, lead, molybdenum, vanadium and zinc varied, depending on the fuel sample. Beryllium was released to a greater extent from coal/straw than the other fuels. Vanadium was partially volatilized from wood-bark and coal/straw, while the largest proportion of the zinc released was from the wood-bark. Lead and molybdenum were retained to a greater extent by "Colombian coal" and wood-bark, respectively. Evidence of the enrichment of certain trace elements on the finer "sinter-ash" particles has also been observed, e.g. for As, Cd, Pb and TI during the combustion of the "Colombian-coal".
