title = "Heat recovery from the exhaust gas of aluminum reduction cells",
abstract = "Close to half the total energy input to the Hall Heroult process leaves the cell as waste heat, which may be harnessed for useful purposes. The heat loss is by several paths of which the exhaust gas carries the second largest energy amount and is the most accessible. An experimental analysis of the exhaust gas was conducted at the 270,000 metric tons per year Nordural aluminum smelter in Iceland. The district heating potential of heat recovery from the exhaust gas was assessed for the local community of Akranes. For this smelter the heat recovery potential is up to 48 MWth. Fouling of heat exchanger surfaces is considered. Particulates were isokinetically sampled in front of the dry scrubber and analyzed for chemical properties and size distribution along with scale buildup on a fouling probe. The chemical composition of the exhaust gas was analyzed. Potential scenarios for heat recovery from this source are presented.",
