The Longview Power plant in West Virginia is fired by pulverized coal. It was designed to be the only power plant that uses acid mine drainage as the water source for its cooling tower.
Mott MacDonald provided Owner’s Engineering services for the Longview Power plant, including conceptual engineering and design, permitting, electrical interconnection, EPC (engineering, procurement, and construction) bid documents and evaluations, and EPC design document review.
The plant’s design includes a supercritical boiler firing 2.5% sulfur bituminous coal, condensing steam turbine generator, and mechanical draft cooling tower.
The plant’s boiler is equipped with state-of-the-art pollution control equipment. The use of acid mine drainage for cooling reduces impact on local waterways, streams, and recreational areas. The drainage is also used for the wet flue gas desulfurization system and to suppress dust around the facility.
