Abstract

With the aim to study the fundamental processes of MSW (Municipal Solid Waste) gasification scheme and to obtain a comparison with existing thermal utilization schemes, an useful model was realized by using the tools of energy and mass balances, and of chemical homogeneous gas equilibrium (as concerns the residual solid, it was assumed that it is constituted only of inert material). By using this model, with numerical simulation we evaluated the influence of air volume on the most important operating parameters: temperature, flue gases volume, gas heating value, gasification yield (η). On the basis of existing data and the obtained results about syngas flow rate and composition we performed a comparison between gasification and direct combustion (considered environmental performances and energetic production aspects).
