The authors have made direct observation of pulsed-laser ignition and combustion of pulverized coals with high-speed video. The ignition and combustion behaviors of amorphous carbon spheres and an anthracite were as expected for heterogeneous ignition and reaction. Surprisingly, the reaction of a high-volatile bituminous coal and a subbituminous coal was accompanied by two broad emissions of light, as detected with a photomultiplier tube. For these coals, high-speed videos revealed that two successive clouds of burning volatiles surrounded the particles, and each cloud was associated with one of the emissions. The authors present a possible explanation for this finding.
