Melting furnace TCF®

The TCF®-process developed by Tenova LOI Thermprocess generates clean, recycled aluminium from contaminated end-of-life scrap with sticking oil, grease, lacquer, plastic or other organic contamination without the need for thermal pre-treatment or the use of salt. All process steps for the scrap recycling until discharging the liquid metal take place in one single aggregate. The TCF® process distinguishes itself with an extremely high metal yield of the metal recovery. The heat recovery with regenerators using ceramic elements and the integrated post-combustion of the carbonization gases resulting from the contaminants reduce the energy required for the process. The TCF® process is thus the ecologically and economically appropriate solution for the recycling of aluminium. Since the TCF® process does not need salt addititves, the resulting dross processing is less costly. Design The Twin-Chamber Melting Furnace TCF® consists of heating chamber and scrap chamber accommodated in one furnace casing. Although they have a common melt bath, their atmospheres are separated from each other. While the scrap chamber operates with an almost oxygen-free atmosphere, the heating chamber with the main burners provides optimum conditions for the complete combustion of the pyrolysis gas that evaporates from the adherent organic contaminants during the scrap heating in the scrap chamber. The liquid metal continuously circulates between both furnace chambers so that in the melt bath a uniform temperature and chemical distribution results. For this purpose, the furnace uses an electromagnetic pump or stirrer. Wide door openings and smooth interior walls allow easy charging, cleaning and
