This study investigates the intricate thermal decomposition behavior and combustion characteristics of two distinct types wheat straw pellets (WSP) represented as T1 (100% straw) T5 (70% straw; 10% sawdust, biochar; bentonite clay). Through a thermogravimetric analyzer (TGA) undergo under varying heating rates (5, 10, 20°C/min) in an air atmosphere, ranging from 25 to 1200°C. Differential analyses reveal four stages biomass components. The results indicate that optimal rate is 20°C/min, resulting highest reaction (∼50%/min) most substantial mass loss (∼55%) for both pellets. Notably, pellet demonstrates lower ignition temperature (207°C, at higher burnout (457°C 10°C/min) compared pellet, indicating its superior suitability combustion. efficiency ranges 61.0 99% within range 300 700°C, similar coal Additionally, thermodynamic properties (Di, Db, C, S) suggest promising potential WSP bioenergy feedstock. Furthermore, demonstrate temperatures (Ti) than T5, indicative rapid energy potential. (Tb) revealed scenarios. These findings hold significance design gasification or reactors industrial utilization biomass. insights gathered this offer valuable guidance designing enhancing systems fostering sustainable practices utilizing agricultural residues production.
