The Arvedi Group will install a waste heat recovery organic rankine cycle (ORC) unit at its steel plant in Cremona, Italy.
The Turboden 100 HR ORC unit, which is designed for 10 MW nominal capacity, will convert the off-gas waste heat from the electric arc furnace (EAF) to electric power. The system configuration includes a saturated steam heat carrier circuit to convey the heat from the furnace exhaust gas to the ORC unit. The waste heat boiler will be installed on the primary EAF off-gas line parallel to the existing quenching tower and will produce saturated steam. The system is scheduled to start up at the beginning of 2017.
