Ignition Rate Measurement of Laser-Ignited Coals [PDF]
, 1997 We established a novel experiment to study the ignition of pulverized coals under conditions relevant to utility boilers. Specifically, we determined the ignition mechanism of pulverized-coal particles under various conditions of particle size, coal type, and freestream oxygen concentration.
