Exemplary Steel Plant Analysis Steel manufacturing facilities consume large quantities of thermal and electrical power in the processing of raw ores and scrap steel into new slabs for hot rolling into sheet steel. Typical heat sources found in steel mills include: reheat furnace flue gas, coke oven flue gas, blast furnace stoves flue gas, and power boiler flue gas. As an example, consider a hot strip steel mill operation reheats steel slabs prior to hot rolling. After preheating furnace combustion air, 1,000 oF flue gas is discharged to atmosphere. A direct flue gas-to-sCO2 waste heat exchanger installed downstream of the existing combustion air heater absorbs waste heat energy and delivers the heated sCO2 to a sCO2 heat engine. The heat engine converts thermal power into electrical power. The subsequent electrical power savings reduces the effective furnace operating cost from $8.60/ton to $6.79/ton of steel processed. The detailed waste heat to power analysis is summarized in Tables 4 and 5.
