Increase in energy efficiency in the production of aluminum can be achieved by recovering heat from the off-gas. However, efficient heat recovery is hindered by the dirty nature of the off-gas containing particulate matter and corrosive gas species, which cause fouling problems.

The aim of the project is to investigate particle deposition, scale formation and their effects on heat transfer in order to further aid in future development of self-cleaning heat exchanger concepts. The work will involve experimental measurements using a probe equipped with sensors and theoretical studies involving computational fluid dynamic simulations.
