Alstom has recently been awarded a contract by Fluor Corp. to provide three heat recovery steam generators (HRSGs) for Dominion Virginia Power’s new 1,300 MW Brunswick County Power Station. The Brunswick facility will be located about 180 miles south of Washington, D.C. near Lawrenceville, Virginia, and will provide enough power to meet the needs of more than 325,000 homes when it goes online in 2016.

Selective catalytic reduction and carbon monoxide catalyst technology embedded in the HRSGs are likely to reduce overall emissions from the plant.

When a gas turbine’s hot exhaust stream passes through the modules of an HRSG, water is converted to steam, which then spins a steam turbine. Each of the Brunswick County HRSGs will be coupled with a MHI501G gas turbine.
