Abstract

Procédé et dispositif de chauffage de matériaux destinés à la fusion. Les matériaux sont chauffés sous une hotte afin de vaporiser leurs constituants combustibles. Des moyens de soufflage sont aménagés pour aspirer lesdits constituants vaporisés et les diriger avec de l'air dans une conduite où ils sont brû1és. On engendre ainsi de la chaleur qui est envoyée aux matériaux à chauffer. Applications : au traitement des déchets métalliques avant leur fusion.
