| Abstract Scope |
Economic and environmental pressures are driving change in the modern aluminum industry, compelling manufacturing sites to optimize their processes to drive down costs and reduce environmental impact. Secondary aluminum melting (recycling) requires only 5% of the energy needed to produce primary aluminum — reducing carbon emissions and providing cost savings for the producer and consumer. Significant improvements in carbon footprint and energy efficiency can be made to aluminum remelting by using smart oxy-fuel burners, low carbon intensity fuels, and Industry 4.0 tools.
In this paper, we discuss different pathways to reduce total CO2 emissions from secondary melting furnaces, using smart “transient heating” burner concepts and low carbon intensity fuels like green hydrogen and ammonia. The paper will demonstrate the reductions in energy costs and carbon emissions which can be achieved. These pathways can assist manufacturers in choosing the optimal solution to decarbonize their melting furnaces. |
