    Limestone Calcination Optimization of Vertical Container Oven
    (INSTITUTO DE TECNOLOGIA, 2015) SAGASTUME GUTIÉRREZ, Alexis; Manoel Henrique Reis Nascimento
    Producing lime demands high energy consumption and leads to significant CO₂ emissions. This study aims to establish a methodology to optimize limestone calcination in standard vertical kilns in Cuba, considering lime quality’s impact on the economic contribution margin. Tools such as exergy analysis and genetic algorithms were used. Major inefficiencies identified include combustion irreversibilities, heat transfer losses, and exergy loss through exhaust gases. Applying the methodology reduced energy consumption by 4.6% and improved lime quality by 5.3%.
