Description
Summary:In this work an analysis of gases’ behavior into primary dedusting system of basic oxygen furnace (BOF) converter was developed. The methodology involves Computational Fluid Dynamics (CFD) to simulate velocity, temperature of gases in combustion for multi-phases systems including solid particles. The influence of the air in the flow, analysis of temperature and gas along the dedusting system and the influence in cooling pipes was investigated. Numerical data were validated with real values of the process. The next step was the implementation of changes in the geometry of the ducts in order to find a more stable situation for the equipment. The best result was obtained by increasing the diameter and smoothing the geometries in curves.
