Controle de exaustão de fornos de cozimento de anodos baseado em lógica fuzzy

Abstract

With the ambient legislation becoming more rigorous all the time the industry has forced to invest in innovative solutions of control, searching to diminish the emissions of pollutants gases of the mobile and fixed sources, exerting better control and treatment of the pollutants comply to the limits imposed by law. Presented in this work, the implementation of an improvement in the exhaust control system for the anodes baking ovens used at the ALBRAS-Aluminio Brasileiro S.A. smelter, located in Barcarena in the state of Pará, aiming at to minimize the pollution caused by the fuel burning in the ovens without compromising the efficiency of the process. For this, a fuzzy logic based system was used, exploiting the experience of engineers, technicians and process operators, a way of getting better control and reliability in the emissions management of the pollutant gases.
