Project Background
Roberts & Schaefer Company was awarded a contract from Southern Illinois Power Cooperative for engineering and procurement of the coal and limestone handling system upgrade at Southern Illinois Power Cooperative’s Marion Generation Station in Marion, Illinois. The system was successfully completed and in operation in 2002.
Coal and limestone are received by trucks for a new CFB unit that was added to the station. New coal and limestone receiving/reclaim hoppers were added to improve receiving and to increase the reclaim capacity from 200 to 300 TPH. The coal hopper has a variable speed feeder/breaker, and the limestone hopper has a variable speed belt feeder. At the transfer tower addition, the existing 24–inch reclaim and silo fill conveyor system was upgraded to 300 TPH with increased belt speeds, new drives, and conveyor components as required. A new silo fill conveyor system with a shuttle conveyor was added to convey coal to four silos and a diverter gate directed the limestone to one silo at the new CFB unit. Insertable bag filter dust collectors were furnished for the silo fill area. The work was coordinated so as not to cause any interruption in the existing station operations.
