Lead is the most recycled metal and our goal in this work is to improve energy efficiencies in the smelting processes used for recycling. In that effort, Oak Ridge National Laboratory is partnering with Gopher Resource, the second largest independent lead recycling company in the United States, to develop a high-fidelity Computational Fluid Dynamics (CFD) model of a direct-fired secondary lead furnace. These high-performance simulations are being developed using first principles modeling with pilot and operational empirical validation. A three staged process is used to tackle the problem. Firstly, a CFD model of an experimental furnace is constructed to validate the combustion model. Secondly, a solid phase furnace feed is added using a Discrete Element Model. Thirdly, and lastly, the full furnace operation is simulated which includes the combustion flow field, particle loading, smelting and melting processes, and formation of slag and lead.
