The ignition, combustion, and emission behavior of crushed corn cob pellets of different shapes and sizes with a chemical binder (Epoxy1092) under certain operating conditions in a fixed-bed combustor were investigated in this study. Also, chemical kinetic parameters are determined by using thermogravimetric and differential thermogravimetric (TG/DTG) analysis data for both pellet and binder. It was found that the activation energy value is 129.82 kJ mol −1 for pellets, while the activation energy value is 109.62 kJ mol −1 for epoxy 1092. The surface and central pellet temperatures histories, the mass loss rates, conversion rate as well as a simple combustion ash analysis are recorded and analyzed. It was found that increasing the starting air temperature and air velocity and decreasing the size of pellet lead to a decrease in devolatilization time, time to reach maximum temperature, char combustion time, and an increase in the total combustion rate. Regarding to emissions; it was found that the CO 2 content increased with increasing the starting air temperature and flow velocity and the maximum CO concentration reaches to 49 ppm at 9.6 ± 1.04% O 2 . The fouling, slagging indices, and ash viscosity were investigated. The corn cob pellets show a relatively high fouling inclination (FI) and a medium slagging inclination.
