Analyzing Energy Performance and Assessing Dry Moisture Content of Briquettes through Numerical Investigations

Abstract

Numerical analysis of briquette performance reveals potential energy savings via optimized moisture content.• Findings suggest energy savings via optimization of moisture content in briquette production. • Briquette moisture optimization could lead to improved efficiency and performance, aiding sustainable energy.This study presents a comprehensive numerical investigation into the energy evaluation and determination of dry moisture content of briquettes, a vital aspect of renewable energy production. Utilizing advanced computational fluid dynamics (CFD) modeling and simulations, we explored key parameters impacting briquette combustion, such as moisture content, size, density, and temperature profiles. The research demonstrates that these factors significantly influence combustion behavior, with the CFD model accurately predicting mass loss curves and burnout times. The process was completed in 10 minutes, reaching a temperature of 300K and yielding gases consisting of CO2, CO, and H2O, while the devolatilization front was assumed to be at 325K. The drying front was estimated to occur within the range of 303K to 310K. This knowledge is pivotal in optimizing briquettes as a sustainable energy source, ensuring efficient energy conversion, and reducing environmental impact. By integrating engineering principles, thermodynamics, and computational modeling, our interdisciplinary approach addresses complex challenges in renewable energy. The research findings underscore the importance of refining and validating these models to advance the understanding and utilization of briquettes as a clean and eco-friendly energy alternative. In a world increasingly prioritizing environmental sustainability and energy efficiency, this research aligns with broader efforts to transition towards cleaner and more sustainable energy sources, offering prospects for a greener and responsible energy future.

“…Biomass is a major player in the renewable energy sector, accounting for over 10% of global primary energy use. Biomass is an umbrella term for a variety of fuel types, including combustible biomass and waste (e.g., agricultural residue), liquid biofuels (like biodiesel and ethanol), [6] solid biomass (such as wood pellets and charcoal), and gaseous fuels (like biogas and landfill gas) [7,8]. The rapid industrialization of rural areas worldwide, particularly in Nigeria, has exacerbated the concentration of greenhouse gases in the atmosphere.…”
