Özet

Almond shell is regarded as one of promising renewable sources for energy in Turkey for biomass gasification. Steam gasification for almond shell supplies remarkably higher gas qualities than air-blown gasification. The aim of this study is to simulate a circulating fluidized-bed gasifier for almond shell gasification in situ steam atmosphere using Cycle-Tempo software (TU Delft, the Netherlands). Effect of gasifier temperature and ratio of steam to biomass were discussed. The outcomes of the circulating fluidized-bed gasifier model demonstrated the high steam amount in almond shell gasification enhances production of H2 and exergy of producer gas. The model was capable of providing detailed data of performance of the almond shell steam gasification in terms of composition of producer gas and exergy as well as lower heating value, and model results are in a good agreement with the experimental results from the literature.
