At Boyne Smelters Limited (BSL) in Queensland Australia, a newcarbon bake furnace was built as part of a AUD $337 milliondevelopment program to replace two existing carbon bakefurnaces. The carbon plant was to have a capacity of 200,000 tpyof anodes. It consisted of a Rio Tinto Alcan AP technologyfurnace, four (4) state of the art fire groups using natural gas, twofurnace tending cranes, an anode handling system and a FumeTreatment Centre (FTC). The plant was commissioned in January2012 and reached full capacity by April 2012. The FTC designincorporated several new features such as newly designed flowdistribution system in the baghouse, microfiber filterbags whichutilize lime pre-coat for improved filtration and a direct dieseldriven emergency draft fan. Similar with the majority of startupsthere were some challenges to overcome, but the carbon bakefurnace and FTC are both fully operational and have achievedoperational and process performance guarantees.
