Thermal metallurgical emissions as a source of renewable energy and waste recycling

Abstract

Articles, parts and pieces made of metals and their alloys are the basis of industrial development as fundamental components in the construction of mechanisms for the metal-mechanical, automotive, aeronautical, naval, military, domestic, etc. industries. They are characterized by their thermo-resistance and refractoriness, due to this, for their manufacture metallurgical processes of casting, shaping, heat treatments are used, which require melting and heating furnaces with temperatures ranging from 750 0C to 2 500 0C, which generate thermal emissions with a high caloric intensity. With this research, the evacuation of this emitted heat is carried out with alternative collectors and recuperators and is used as a source of energy for: The generation of hot water and vapors, used in technological and domestic processes such as: sterilization of laboratory tools and washing of textile confections and other fibers and in the preparation of food in companies; Heating of water for domestic use and hygiene of metallurgical workers, contributing to the sustainability of the health of the human environment by avoiding sudden changes in temperature in the toilet; Production of electrical energy by thermo transfer.
