Warrior Run Generating Station

Warrior Run Generating Station, owned by the AES Corporation, is a 205 megawatt cogeneration plant located south of Cumberland, Maryland, at 11600 Mexico Farms Road. In addition to electric power, the plant also produces food-grade carbon dioxide.Design and operationThe plant uses fluidized bed combustion (FBC) technology, in which bituminous coal and finely ground limestone are injected, using air, into the boiler. Air keeps the limestone and coal suspended in a fluid-like condition. The limestone reacts with sulfur dioxide, released during combustion of the coal, removing this pollutant from the plant's emissions. With the enhanced sulfur dioxide removal due to the FBC technology, Warrior Run can burn approximately 400000ST of coal from Maryland each year, which tends to be of a higher sulfur content. During 2007, 100 percent of the coal burned at Warrior Run was mined in Maryland.The FBC boiler operates at a lower temperature compared to other coal-fired boiler technology, reducing production of nitrogen oxides. Injection of ammonia and a selective non-catalytic reduction system are also used to remove nitrogen oxides. A baghouse removes particulates from the plant's air emissions.
