bituminous and anthracite coals used for steam and power generation; and (b) brown coal (subbituminous and lignite), which is used mostly as onsite fuel. Coal has a wide range of moisture (240%), sulfur (%), and ash content (540%). These can affect the value of the coal as a fuel and cause environmental problems in its use.
