COMBUSTION OF LIGNIN-RICH RESIDUES WITH COAL IN A PILOT-SCALE BUBBLING FLUIDIZED BED REACTOR - (PPT)

摘要

1) the gaseous emissions did not significantly change with respect to coal or to reference biomass-coal mixture at least until the mixture content of lignin-rich residues was 30-40%w; 2) the particulate emissions increased when lignin-rich residues were fed with coal, but, at the same, the particulate carbon concentration was significantly reduced. 3) Agglomerates of bed particles were not observed, but a significant enrichment of metals like Fe, Mg, Na, Ca and K, most of them probably coming from the ash of lignin-rich residues, was observed when the FBC was operated for long time and at high temperature.
