The Basics There are four basic types of coal Lignite subbituminous bituminous and anthracite Lignite is the lowest rank of coal with the lowest energy content Lignite is crumbly and has high moisture content Lignite accounts for about 7% of U S coal production Subbituminous coal has a higher heating value than lignite Subbituminous coal typically contains
Anthracite is the most desirable type of coal because it contains more energy than other types and it is also the most environmentally friendly of them because of purity Unfortunately only approximately 1% of all the coal is anthracite So we also burn bituminous coal lignite (brown coal) and even peat which is the source material of coal

Quick rough strokes will yield the best results One thing to keep in mind is that hand fired coal stoves require chimneys So if you don't already have one you're going to have to make some room In the end operating a hand fired coal stove isn't that different from operating a wood stove but it'll take a lot less coal to heat your home
The coal formation process involves the burial of peat which is made of partly decayed plant materials deep underground The heat and pressure of burial alters the texture and increases the carbon content of the peat which transforms it into coal a type of sedimentary rock This process takes millions of years Types or "ranks " of coal are determined by carbon content There are four
