how to adjust price account of moisture coal

How to reduce specific coal consumption in a thermal power ...

Importantly, the moisture content of coal dramatically affects its Btu content because during combustion the evaporation of water soaks up heat. Thus, too much excess moisture could lead to either a deadband price adjustment or a calorific value price adjustment. On the other hand, the utilities do not want totally dry coal either.

COAL CHARACTERISTICS - Purdue University

Lignite contains 25%–35% carbon and has the lowest energy content of all coal ranks. Lignite coal deposits tend to be relatively young and were not subjected to extreme heat or pressure. Lignite is crumbly and has high moisture content, which contributes to its low heating value. Lignite accounted for 8% of total U.S. coal production in 2019.
