In order to make clear the combustion behavior of pulverized coal(PC), the combustion characteristics of a single PC in the mixture of oxygen and nitrogen gases were measured by using the combustion apparatus equipped with CO2 LASER, high speed camera, image analyzer and pyrometer.
The ignition time of PC was not dependent on the chemical composition of PC, but the burning time and the maximum volume expansion of PC was dependent. Therefore the burning time can be estimated from the composition of PC. The ignition time can be shorten with increase of the irradiating density of LASER, and the burning time can be shorten with increase of oxygen concentration in the mixture of oxygen and nitrogen. The burning time was not dependent on the irradiating density of LASER.
