THERMODYNAMIC ANALYSES OF ENERGY UTILIZATION AND POLLUTANT FORMATION CONTROL IN SECONDARY ALUMINUM MELTING FURNACES

摘要

This paper presents thermodynamic analyses of energy utilization according to the energy balance in reverberatory, secondary aluminum melting furnaces, from which the overall energy efficiency and major heat losses are derived. The energy availability concept is used to analyze maximum energy efficiency and minimum flue gas heat loss in the secondary aluminum melting. Methods that can improve energy efficiency and reduce pollutant emissions from melting operations are also addressed.
