Abstract

Biomass cofiring has emerged as a promising approach to reducing greenhouse gas emissions from coal-fired power plants. This study employs Computational Fluid Dynamics (CFD) to analyze the thermal and emission performance of cofiring coal with sugarcane bagasse in a stoker-type boiler. Simulations were conducted using ANSYS Fluent to evaluate combustion characteristics at sugarcane bagasse biomass percentages of 0%, 35%, and 70%. The results show that increasing the proportion of bagasse reduces furnace temperature and CO₂ emissions, attributed to the biomass's lower carbon and higher oxygen content. Specifically, the average furnace temperature drops from 963.94 K to 862.47 K. Correspondingly, CO₂ emissions decrease due to the lower carbon content of bagasse, while the mass fraction of O₂ in the flue gas increases, reflecting reduced demand for excess air. These findings support the viability of sugarcane bagasse as a co-firing fuel to enhance combustion sustainability and minimize environmental impact.
