The grinding process of coal is a process in which the mechanical force continuously breaks the chemical bonds in the coal. A large number of covalent bonds in the coal undergo homolytic cracking under the action of mechanical forces, resulting in a large amount of active free radicals. This process can be confirmed by the change of free ...
Pulverized fuel ash is formed during the process of combustion of pulverised coal in the furnace of the power station's boiler. The coal is ground to powder-coal in coal mills, before being blown by compressed air into the furnace and burned at temperatures ranging between 1300 and 1600 °C, depending on the type of boiler in question.
