Abstract

A facility (50) and a method for thermal cleaning and separation of metal parts (12), preferably windings from a stator of an electric motor and/or generator, where the stator windings are embedded in an organic and insulating material, where the stator is placed and heated under controlled conditions in a heating chamber (6) comprising a gas mixture of more than 86 vol% inert gas and less than 14 vol% oxygen, such that the organic covalent bonds of the organic material will undergo pyrolysis, resulting in the production of a char product and volatile organic products that will evaporate into the gas mixture in the heating chamber (6). The flue gas in the heating chamber (6) comprising a mixture of oxygen, volatile organic products and inert gas is then subjected to an oxidation process by addition of a oxygen enriched gas mixture, resulting in the oxidation of the volatile organic products into CO2 and O2.
