Propensity of coal to self-heat - United States Energy ...

Great River Energy of Maple Grove, Minn., has selected the WorleyParsons Group to exclusively distribute licenses for the technology, which essentially uses waste heat from a power plant to reduce moisture content in lignite coal. Great American Energy, a 50-50 joint venture of Great River Energy and the North American Coal Corporation, will also market the technology, whose first user will be the utility's Spiritwood Station under construction near Jazenithwn, N.D.

of moisture content, the heat produced by oxidation is dissipated by moisture evaporation and coal self-heating is significantly delayed. More recently, using similar method it has been reported that an Indonesian high-moisture sub-bituminous coal was found to undergo oxidation most rapidly when its moisture content was reduced to about 25% of ...

total moisture content of coal | Relative Humidity | Humidity

Moisture absorbs heat, so high moisture content in coal reduces the relative efficiency of heating when a coal is combusted. This is why low-rank, high-moisture coals have lower calorific values (Btu/lb) than high-rank, low-moisture coals.

Specific heat capacity of coal usually increases with moisture content, decreases with carbon content and increases with volatile matter content [2]. Specific heat capacity of coal as a function of temperature and volatile matter. Heat capacity is the quantity of heat required to change the temperature of substance by a given amount.
