Analysis the Process Parameters of Fluidised Bed Gasification System Using Corn Stalks

Abstract

The present research incorporated the parametric study of process parameters such as bed temperature (T), pressure (P), equivalence ration (R), feed rate (F) and particle size (S) which influence the composition of the producer gas, tar yield and cold gas efficiency. Six major components of the producer gas such as O2, H2, CO, CO2, CH4, and N2 were analyzed in the laboratory along with the evaluation of tar yield and cold gas efficiency. It was observed that the concentrations of hydrogen, oxygen nitrogen and carbon monoxide were increased with rise in gasification temperature, pressure and equivalent ratio (0.2-0.35). On the other hand, higher equivalence ratios (0.4-0.5) caused to decrease the concentrations of hydrogen, oxygen, nitrogen and carbon monoxide. Higher equivalence ratio also resulted in more gas yields and cold gas efficiency due to increase in the exothermic reactions. Furthermore, it was observed that the CH4 and CO2 decreased with the increase of temperature and pressure. The developed model was made a good prediction for the experimental data.
