Design and numerical simulation of the heat exchanger for heat recovery system with melting furnaces for melting secondary a uminums

Abstract

Many industrial technology equipment produces residual (waste) heat. This heat in the form of combustion allows the use of enthalpy drop for heat recovery and can be used to power other devices, which may partially or completely replace the fuel or energy. Significant limiting factor in the construction of systems for heat recovery, however, dust flue contained in flue gas, which adhere to the heat transfer surface area, and when the impossibility of cleaning them often lead to malfunctioning of these devices. This article offers the possibility to use this energy through regenerative devices. © Owned by the authors, published by EDP Sciences, 2013.
