Italian Steelmaker Adding Waste-Heat Recovery System to EAF
06/07/2016 - Italy’s Acciaieria Arvedi is installing a waste-heat recovery system at its Arvedi facility in Cremona, according to a supplier on the project.
Turboden, a group company of Mitsubishi Heavy Industries Ltd., said it is providing the system’s Organic Rankine Cycle turbogenerator, which will have a nameplate capacity of 10 megawatts. The generator will be fired by offgas waste heat from an electric arc furnace at the mill.
Turboden said the system will incorporate a saturated steam heat carrier circuit that will transfer heat from the furnace’s exhaust gas to the generator. The waste heat boiler, to be supplied by Tenova, will be installed on the furnace’s primary offgas line in parallel to the existing quenching tower.
The company estimates that the system will cut carbon dioxide emissions by 23,300 metric tons annually through the power savings provided by the system.
