Heat Recovery from an Aluminium Furnace for Air Pre-Heating and Stock Drying. A Demonstration at London and Scandinavian Metallurgical Co. Ltd. Final Report

摘要

By installing heat recuperation equipment on an existing furnace, the London and Scandinavian Metallurgical Co. Limited (LSM) achieved production cost savings calculated to be worth Pound 44,600/year. With plant and installation costs of Pound 67,500, the annual savings gave a payback period of only 18 months. The project which was partially funded by the Energy Efficiency Demonstration Scheme involved the installation of a cascade of heat exchangers to extract, from the flue gases, heat which could then be used to pre-heat the combustion air and incoming charges of ingots.
