Complex and Efficient Waste Heat Recovery System in Aluminum Foundry

Abstract The study presents the evaluation of a heat recovery system in a Romanian aluminum foundry. The study was based on a thermal power balance that revealed on one side that the components of the balance is in good agreement with similar results presented in the literature and revealed on the other side the heat recovery potential from the available waste represented by exhaust gases. The proposed heat recovery from waste is capable to recover more than 25% of the total thermal power of the burners, equivalent with more than 60% of the available waste.
