Batchwise fluidized bed combustion of a coal has been carried out to investigate the generation of elutriable carbon fines by attrition of the burning char. Differences between the purely mechanical attrition and the combustion assisted attrition of the char have been outlined. The time required to activate the char surface as regards attrition explains certain features of carbon elutriation curves. Attrition rate constants determined from these curves are compared with those previously found by continuous fluidized combustion of the same coal. 20 references, 13 figures, 3 tables.
