Coal is the primary fuel for producing Electricity. Some of the characteristics of coal have profound influence on the day to day working and economics of the power plant. This article discusses Calorific Value and Moisture. Calorific value is the most important parameter that determines the economics of the power plant operation. It indicates the amount of heat that is released when the coal.
