Abstract

A zero dimensional steady model is assessed that describes the thermo-chemical conversion process of a solid fuel (biomass or waste) taking place into a gasifier. The model considers a 0D system where the dry and ash free low grade fuel reacts with air to form a syngas. This last is characterized in terms of composition and lower heating value on the ground of the assumption of thermo-chemical equilibrium at the gasification temperature. The model validation is performed over a continuous interval of variation of the initial moisture content of the treated biomass. The effect of a radiative heat flux on the gasification is also accounted for. Various refuse derived fuel (RDF) are then considered. The released syngas value is analyzed as a function of the ratio between the gasifying agent and the treated fuel amount. The optimal operation point of the gasification system is found for the highest quality of the released syngas. (literal)
