Analysis of devolatilization of predried large coal particles in fluidized beds requires consideration of both the chemical kinetics of coal decomposition and transport processes. Models available either assume the devolatilization particle to be isothermal (whereas it may be shown that, in general,

A non-interference technique has been developed for measuring devolatilization rates of large coal particles in a cylindrical fluidized bed at 850ยฐC by on-line analysis of oxygen and carbon dioxide concentrations in the flue gas. The experiments were conducted over a range of inlet oxygen concentrat
