Abstract Scope |
INALUM’s anode baking furnace previously relied on high-speed diesel (HSD), incurring high operational costs and emissions. A conversion to natural gas (NG) was undertaken by replacing the burner system and auxiliaries, completed by a local Indonesian vendor from January to July 2023. Post-installation assessments revealed a 45% reduction in production costs, translating to annual savings of IDR 47.17 billion, with a 158% ROI and a payback period under seven months. Crucially, anode quality—measured by density and flexural strength—remained within specification, while SOx, HF, and dust emissions fell well below regulatory limits. This initiative demonstrates that adopting NG in anode baking furnaces can significantly lower costs and enhance environmental performance without compromising product quality. The paper highlights the conversion process, key operational outcomes, and implications for improving sustainability in aluminium smelting operations. |
