Abstrakty

EN

The ash obtained by combustion of energy grasses (five cultivars, three hybrids and clover-grass mixture) was studied by mineralogical and geochemical methods. X-ray diffraction was used for mineralogical phase analysis, electron microprobe for analysis of chemical composition of ash particles. Ash melting temperatures were determined and discussed in relationship to phosphorus concentrations.

PL

Popiół uzyskany ze spalania traw energetycznych (pięciu odmian, trzech mieszańców i mieszaniny trawy i koniczyny) badano metodami mineralogicznymi i geochemicznymi. Metodą dyfrakcji rentgenowskiej fazy mineralogicznej, do analizy składu chemicznego cząstek popiołu wykorzystano mikrosondę elektronową. Określono temperaturę topnienia popiołu i wykazano jej zależność od zawartości fosforu.
