A detailed model for the steady-state combustion of a coal particle considering both surface oxidation and volatile combustion is presented. By solving the model equations in the absence of surface oxidation at various ambient gas temperatures, the homogeneous ignition temperature is determined as t

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.

Experiments are reported giving visual observations of ignition--the emission of light or flashing--and the changes of gas composition--O:, CO:, and NO--in a laboratory drop-tube furnace fed continuously with pulverized coal and air in near-stoichiometric proportions. As the furnace is slowly heated

The reported combustion kinetics of pulverized coal from two types of experiments are compared: the first from measured rates of burnout at particle temperatures of 900-2200K and the second from an analysis based on the minimum gas temperatures at which coal ignites, corresponding to particle temper
