Abstract
The relevance of pellet production to ironmaking industry is rising every year, following the rise in production of pellet feed. Among the pellet induration systems, the traveling grate furnace (TGF) is the most important, particularly in Brazilian market. The paper presents a software that allows one to simulate it, evaluating product and process characteristics. The simulation follows a deterministic, fundamental-based mathematical model of the TGF, which considers the gas network, predicts pellet properties and energy consumption and productivity of the process. The mathematical model is composed by two coupled sub models: a model of pellet induration concerning the physical and chemical phenomena that occurs in the bulk of the pellet bed and a gas flow model which solves the gas flow between the different zones of the furnace. The user interacts with the model through a graphical interface. The software is applied to a particular case and the results are discussed.
