Project Location: Georgetown, South Carolina

Project Completion: September 2002

Project Description:

ESI was the EPC Contractor for this carbon burn-out facility. This facility utilizes patented technology developed by Progress Materials to reduce the high carbon content of fly ash resulting from low NOx burner conversion of pulverized coal-fired utility boilers. The heat recovered from this process results in an improvement to the utility boiler heat rate. The carbon burn-out plant processes the fly ash in an efficient manner to reduce the carbon content and provide a superior additive product for concrete. This facility was constructed at state-owned utility Santee Cooper’s Winyah Electric Generating Station and was designed to accept all of the ash produced by Santee Cooper’s Grainger Electric Generating Station in Conway, SC as well as the majority of the ash produced at the Winyah Station. The new facility will allow for the truck shipment of ash from Grainger Station with pneumatic unloading into receiving silos. This ash will be combusted as well as the ash from Winyah Station with the captured heat being returned to the Winyah heat cycle and the marketable ash being sent to a 1,000-ton loadout silo or to a 125-foot diameter concrete dome for storage and later reclaim to the loadout silo.
