PDF 1.7 Lignite Combustion

The lignite in both areas has a high moisture content (20 to 40 weight percent) and a low heating value (5,000 to 7,500 British thermal units per pound [Btu/lb], on a wet basis). Due to high moisture content and low Btu value, shipping the lignite would not be feasible; consequently, lignite is burned near where it is mined.
