Estudo da influência do excesso de ar na composição de saída de fornalha siderúrgica real empregando conceitos termodinâmicos e modelagem matemática

Abstract

Steel industry produce four by-products with significant capacity of power generation and can be used as fuel in thermoelectrical plant. The burning these by-products in the presence of air provides the energy content of the fuel and produces exhaust gas. The objective of this study is to predict the concentration of the furnace’s exhaust gases of a boiler steelmaking with the variation of available air. For this, the principle of the minimization of the free energy Gibbs was adopted to describe the system. This methodology proved to be effective to describe the system when different air feed are adopted.
