Abstract

A presente contribuição técnica apresenta o trabalho desenvolvido e implantado pela equipe técnica e operacional da Gerência de Geração de Energéticos focado na otimização da absorção de combustíveis siderúrgicos (Gás de Coqueria - GCO; Gás de Aciaria - GLD; e Gás de Alto Forno - GAF), na geração de energéticos (Energia Elétrica, vapor e ar soprado), e a redução no consumo de Gás Natural. Por ser estratégico, este buscou-se a melhoria na garantia operacional da Usina, quanto à energia em Gcal gerada e disponibilizada internamente. Visando o menor investimento, o grupo voltou-se então para a implantação de recurso de análise rápida a frente de trabalho e de planejamento de geração, onde se buscou um modelo matemático na eficiência energética da CTE2. Tomando-se como base os recursos do green belt, e por se ter várias entradas e várias saídas no processo, optou-se pelo método estatístico de regressão na concepção dos coeficientes de regressão PLS (Partial Least Squares) na composição do modelo matemático e do simulador. O trabalho detalha o desenvolvimento e implantação do simulador e um melhor planejamento de consumo de combustível siderúrgico contra um menor volume de GN.

 

This contribution presents the technical work developed and deployed by the technical staff and operational management of Generation of Energy focused on optimizing the absorption of iron and steel fuel (Coke Gas - GCO; Gas Steelmaking - GLD; and Blast Furnace Gas - GAF) in the generation of energy (Electricity, steam and air blown), and reduced consumption of natural gas. By being strategic, it sought to guarantee the improvement in operating the Plant, the energy generated in Gcal and made available internally. Aiming to lower investment, the group then turned to the deployment of analytics fast forward to working and planning of generation, where we seek a mathematical model of energy efficiency CTE2. Taking as basis the resources of the green belt, and having multiple inputs and multiple outputs in the process, we opted for the statistical method of regression in the design of regression coefficients PLS (Partial Least Squares) in the composition of the mathematical model and simulator. The paper details the development and implementation of the simulator and a better planning of fuel steel against a lower volume of NG.
