1994-4-1 We present a novel experiment to study the ignition of pulverized coal. A dilute stream of particles is dropped into a laminar, upward-flow wind tunnel with a quartz test section. The gas stream is not preheated. A single pulse from a Nd:YAG laser is focused through the tunnel and ignites the fuel.

Ignition of a cloud of pulverized coal is not a simultaneous event. A typical pulverized coal particle (-200+300 mesh) will burn out within one second. Thus, if a flame is to be propagated, the particles ignited by an ignition energy source must transfer energy to and ignite some of their neighboring particles.
