| 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 melting of the burden material. The melting logic incorporates externally-imported point clouds using dynamic linked lists to enable creation and destruction of burden material. Each point retains information external to the numerical grid, such as composition. A transient simulation with burden melting shows the deformation of the burden shape during heating and is compared against prior static burden shapes and heating profiles. |
