Refined coal Refined coal Refined coal is the product of the application of a coal upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned. The goals of pre-combustion coal upgrading technologies are to increase efficiency and reduce emissions when coal is burned. Depending on the situation, pre-combustion technology can be used in place of or as a supplement to post-combustion technologies to control emissions from coal-fueled
A. B. Brown Generating Station A. B. Brown Generating Station The A. B. Brown Generating Station is a four-unit, 700 megawatt (MW) power plant, located on the northern bank of Ohio River, east of Mount Vernon, Indiana and southwest of Evansville, Indiana just west of the Posey-Vanderburgh County Line. Each of the two coal-fired units has a name-plate capacity of 265.2 MW. Bituminous coal is used as a primary fuel type, which can be substituted for natural gas. There are also two gas turbine units, 88.2 MW of nameplate capacity each. The facility is owned by Vectren (formerly Southern Indiana Gas and Electric Company). In
