Analysis of Combustion Curve for Biomass Co-combustion with Coal

Biofuel-coal co-combustion represents an innovative approach tocombustion that optimally harnesses biomass energy alongside coalresources, resulting in a significant reduction in pollutant emissions. Thisstudy investigates the combustion characteristics of peanut shell biomass,coal, and their blends at varying heating rates (5, 10, 20, and 40℃/min) anddifferent blending ratios. The effects of these parameters on the combustionprocess were systematically analyzed. The results indicate that increasingthe heating rate causes a shift in the TG curve towards higher temperatures.Notably, peanut shells exhibit lower characteristic combustion temperaturesand faster burning rates compared to coal. Furthermore, incorporatingpeanut shells into coal leads to earlier ignition times and enhancedcombustion properties, thereby substantially improving biomass utilizationefficiency.
