The generation and elutriation of attrited carbon fines during the fluidized combustion of a metallurgical coke has been investigated by means of a 140 mm ID fluidized bed combustor. The influence of a number of design and operational variables of the combustor, including feed coke particle size, bed temperature, bed height and excess air factor, has been tested. The relationships between attrited carbon rates and bed carbon loading and exposed surface have been outlined, and compared with those previously found under similar experimental conditions burning a coal. 8 figures, 2 tables.
