The Role of Coal Characteristics in Boiler Operation - Babcock Power

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.
