Biomass gasification: the effect of equivalence ratio on syngas quality in the case of externally heated reactor

Biomass gasification is a thermal process that aiming at obtaining the possible best quality of the product gas, in terms of heating value and composition. The reaction temperature is one of the most important parameters affecting the syngas quality. Several experiments show a close link between the air mass injected within the reactor (the equivalence ratio) and the temperature reached. In the proposed paper we investigate the effect of varying the equivalence ratio in the case of an externally heated reac-tor, on the temperature distribution within the reactor, and on the syngas quality (i.e., composition and low heating val-ue).
