SunCoke Energy's heat-recovery technology converts waste heat into steam and electricity. Benzene and other pollutants generated in the long hours of baking coal are incinerated inside the coke ovens, eliminating the need for a chemical byproducts plant and disposal of hazardous waste. Sole flues and hot gas ducts provide sufficient time, temperature and turbulence to ensure complete destruction of virtually all organic compounds, creating hot inert gasses. The negative pressure employed by SunCoke Energy's ovens pulls air into the oven through air ports on each oven door and sole flue, and the movement of air through the oven maximizes temperature. Excess heat is converted to steam and/or electricity through heat recovery steam generators and steam turbines. A one million ton-per-year coke facility can generate approximately 100MW of electricity.
