Devolatilization times of large (0.1 and 0.2 g) Utah hvBb and North Dakota lignite coal particles, in the range 15-30 s, were measured in air at 101 and 507 kPa, at air temperatures of 900 and 1200 K in a convective flow reactor. Visual observations indicated infrequent heterogeneous ignition of the lignite prior to devolatilization and occasional explosion of bituminous coal particles during devolatilization...
Mass losses and burnout times of large (0.1, 0.2 g) char particles at pressures of 101-760 kPa were measured in a newly designed high-pressure reactor. A cantilever balance measured instantaneous particle mass and an optical pyrometer measured particle temperature continuously. The process was also videotaped. Sixty-two combustion experiments were conducted with a bituminous coal and a lignite...
