Many of the existing pulverised coalfired (PCF) power stations are operated at a fixed steady load ( baseload operation). There is however a growing requirement for load following or flexible operation, which requires flexibility in most of the components of the power station. Flexibility and efficiency can be improved by close control of the coal .
With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to % or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels .
superheater pendants. Coal fineness, when sampled from one of 8 pipes always would show 70% + passing a 200 mesh sieve. Yet the flyash was poor, and fuel balance appeared poor. Later, by the STORM® approach, using the STORM® Isokinetic Coal Sampler, all eight pipes were sampled and the fineness samples, weighed and sieved for all eight pipes.

While renewable energy has undergone wide and rapid deployment, coal is still expected to be the main source of fuel for producing base load power in the near future. This is because coal reserves are expected to last for the next century and its cost is still relatively cheap. However, the emissions from coal combustion are a major environmental concern.
temperatures above ignition points, the OEM coal fineness standard required reevaluation. Low NOx firing configurations require no less than 75% passing 200 Mesh with % passing 50 Mesh. Coal fineness is not always required for acceptable NOx emissions, as some burners have performed with compliance NOx levels and poor coal fineness.
