Improving the Efficiency of Power Plants Firing High

Unfortunately, plants that utilize high-moisture coal pay a substantial price in efficiency. When such coals are burned in utility boilers, about 7% of the fuel heat input is used to evaporate and superheat the moisture in the fuel. Most of this lost heat can be attributed to the energy needed to evaporate the moisture in the fuel.
