Description of the source (including control equipment). Please see the attachments for source or process flow diagram: Edgecombe Power Station is a cogeneration plant which combusts bituminous coal in four (4) stoker-fired boilers, each rated at approximately 375 million Btu heat input per hour, to produce steam. A portion of the steam can be sold to an industrial host for use in their manufacturing process(s). Any steam not sold to an industrial host is used to drive a turbine-generator to provide electricity that is sold to an electric power cooperative. The boilers are traveling grate, overfeed stoker boilers manufactured by Combustion Engineering. Industry/SCC/NAIS221122
