The Role of Coal Characteristics in Boiler Operation

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. In addition some sustaining fuel (oil) may be re- quired for good combustion.
