Resumen

QUENTAL-DE-ARAUJO, Eder; NEVES-TEIXEIRA, Flávio  y  VILALTA-ALONSO, Guillermo. Impact assessment of intermediate processes of steelmaking in electricity cogeneration of steel mill companies. Ingeniería Mecánica [online]. 2015, vol.18, n.3, pp.158-165. ISSN 1815-5944.

The steel industry is one of the most energy-intensive industry sectors, accounting also for the generation of co-products with high added energy, among them stands out the process gases. These fuels supply part of thermal demand from the steel mill companies and are typically utilized for cogeneration of electricity. Thus even with all the amount and complexity of variables involved, a clear and accessible methodology developed by [5] was applied to predict and simulate the cogeneration of electricity. Therefore this study aims to evaluate the sensitivity of the change in production of intermediate processes in cogeneration. It was noted that some processes such as coke oven, blast furnace and steelmaking have a direct relationship between increased production and cogeneration capacity, but in other cases such as sinter plant and rolling mill the increase of production causes a decrease in the availability of fuels for thermoelectric power plant.

Palabras clave : steel mill; forecast; cogeneration; process gases; intermediate processes.
