2. The smaller the piece of coal, the more efficiently it will burn -- so it's no surprise that a lot of work has to be done to get the coal ready for the boiler. Chunks of coal are first run through a crusher and then through a pulverizer, where they are ground to a powder the consistency of flour.

Today's coal-fired utility boiler operation needs pulverizer designs to supply pulverized coal with required throughput and coal fineness, and also perform with lower specific power consumption, especially at reduced mill load.
Pulverized coal combustion systems offer a viable solution to all these problems, wherein coal is reduced to a fine powder in grinding mills and projected into the combustion chamber through a hot primary air current. To ensure complete combustion, supplementary air (known as secondary air) is delivered separately to the combustion chamber.
If the calculated speed at step 2 is < than the max speed for the screw diameter selected, the design can be kept. If the calculated speed at step 2 is > than the max speed for the screw diameter selected, the design is not suitable and the calculation must be run again by changing a parameter, typically the diameter.
