explore its fuel properties that are necessary for estimating combustion behavior.
We will also discuss the main issues regarding combustion phenomena both inside
and surrounding solid particles and the final stage of combustion. Finally, we will
briefly discuss the reaction phenomena of pulverized coal under high temperatures
air combustion conditions.
