Batch fluidized bed combustion of 5 mm particles of char of the South African bituminous coal already used in this research has been carried out in the 40 mm ID combustor previously described (DOE Reports N DOE/PC40796-1 and -2) to investigate the generation of fines due to the abrasion of bed solids on the surface of burning particles. Experiments have been performed by operating the bed with different oxygen concentration in the fluidizing gas, namely 21, 10, 4.5, 1.4, 0.75 and 0% O/sub 2/. Attrition rate constants k obtained working out data collected under these oxidizing conditions are presented.
