 · Moisture absorbs heat, so high moisture content in coal reduces the relative efficiency of heating when a coal is combusted. This is why lowrank, highmoisture coals have lower calorific values (Btu/lb) than highrank, lowmoisture coals. Moisture adds weight to coal, and also contributes to spontaneous combustion in lowrank coals, and as such, affects handling and transport. Moisture can ...

Lignite, a crumbly brown rock also called brown coal or rosebud coal, retains more moisture than other types of coal. This makes it expensive and dangerous to mine, store, and transport. It is susceptible to accidential combustion and has very high carbon emissions when burned. Most lignite coal is used in power stations very close to where it was mined. Lignite is mainly combusted and used to ...
