Abstract Scope |
The recycling of spent lead-acid batteries, typically performed in secondary lead reverberatory furnaces, is an energy intensive process. Internal process behaviors such as the movement of the lead burden can strongly influence productivity and furnace reliability. Experimenting with live process parameters is costly and risky to the operation, so optimization of the process using computational modeling is an increasingly common approach. In this study, a CFD simulation of a reverberatory furnace is created with additional user-defined functions to model movement of the burden material. The burden material is coupled with a pseudo-reaction behavior to approximate the melting/smelting of the burden material and production of liquid lead. This allows for the computational investigation of flow patterns, temperature distributions, productivity rates, and residence times, and emissions profiles. The results of the model give insight into potential charging-rates optimizations and the influence of burden shape on furnace performance. |
