The Role of Coal Characteristics in Boiler Operation

For medium volatile coals, it is usual to pulverize the fuel such that 70% will pass a 200 mesh screen. For low volatile coals, it is recommended that the size of the pulverized coal be finer, or 75% through a 200 mesh screen. And for anthracite fuels with volatile content down to the 2 to 10% range, we would recommend 85 to 90% through a 200 mesh.

Coal dust - Wikipedia

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal.It is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.
