The work during the period 1 March-31 May 1983 has been directed to test fragmentation and attrition occurring during the fluidized combustion of two English coals: marine Welsh Coking Coal and Snibston Bituminous Washed Single Coal, both supplied by National Coal Board, U.K. Time-resolved bed carbon loading and particle size distributions, and instantaneous carbon attrition rates have been determined in batch fluidized combustion experiments using laboratory scale apparatus and techniques described in DOE Reports No DOE/PC40796-1 and 2. Correlations between carbon attrition rates and bed carbon exposed surfaces provide attrition rate constants. Results for the two coals are compared with each other and with the results obtained with the South African coal previously tested. 16 figures, 2 tables.
