| Abstract Scope |
Rotary melting offers recyclers a pathway to economic recovery of base metals, if attention is given to managing the OpEx pennies, so to speak. The focus of this paper brings together three such advancements: 1) MPOT-Oxial, our advanced algorithm for utilizing the potential energy from organic-laden scrap to improve productivity, yield, and purity; 2) Air participation via our MPOT-Air/oxy/fuel burner which incorporates convective energy into the melting process, 3) Modeling approach for positioning burners in each individual melter to optimize the pyrolysis process, dramatically improve the homogeneity of the temperature, while reducing refractory wear. Bottom Line: combining these technologies will result in lower operating costs ($/lb) by improving a rotary melters’ productivity, lowering dross formation, minimizing pure oxygen participation, dramatically improving the homogeneity of the refractory temperature, reducing wear on the wall opposite the burners (often the charge door), while dramatically reducing the carbon footprint of the melter. |
