Waste heat recovery in aluminium smelters: technical and economic analysis
Aluminium smelter are energy intensive and not particularly energy efficient, as most of the energy required to produce aluminium is lost along the production line. This is the reason why it is mandatory to perform a detailed analysis of the thermal wastes produced in these factories. The main objective of this project is to investigate the solutions to recover the thermal wastes and to convert them into useful power. The feasibility of these solutions are analysed by considering technological and economic aspects: in this way, a reliable solution to improve the energy efficiency in aluminium smelter is provided.
