The analysis of individual mill design operation is complex; so, for simplicity we will consider a typical mill layout for one mill type only. As VSMs have come to represent the bulk of the power station mill fleet, the explanation of mill operations will be based on this mill type. Fig. illustrates the typical key components of a VSM.

Coal mills use static or dynamic pneumatic classifiers to select the correct cut size and consistency for combustion. For coal, the industry standard cut size for a classifier is that 75% of coal delivered to the burner must pass a 200 mesh screen (75 μm) [6], and for biomass the standard classifier setting is 1 mm [7].

Synthetic fuel production by indirect coal liquefaction. This paper reports detailed process designs and cost assessments for production of clean liquid fuels (methanol and dimethyl ether) by indirect coal liquefaction (ICL). Gasification of coal produces a synthesis gas that can be converted to liquid fuel by synthesis over appropriate catalysts.

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

CHP generates electricity and heat from a single fuel source. Traditional heating plants emit varying amounts of CO 2 depending on the fuel used. Thus, even a simple fuel switch may reduce CO 2 emissions by nearly 50%. Additionally, converting the plant into a GTpowered CHP or a Combined Cycle Power Plant with heat extraction can significantly improve its electrical efficiency.
