Coal particles with diameters of 3-11 mm were injected into a small, hot bed of sand fluidized by nitrogen. Volatiles evolution was followed by sampling the exit gas stream and subsequent analysis by gas chromatography. Three Australian coals covering a range of volatile matter were studied and the
## Abstract The elutriation of fines from fluidized beds of two‐ and multiparticle systems is investigated. Materials used are glass beads and coal powder with air and helium as the elutriating gases. A specific elutriation rate constant which takes into consideration the particle stratification a
