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,
Devolatilization times of large (0.1 and 0.2 g) Utah hvBb and North Dakota lignite coal particles, in the range 15-30s were measured in air at 101 and 507 kPa, at air temperatures of 900 and 1200K in a convective flow reactor. Visual observations indicated infrequent heterogeneous ignition of the li
