Prediction of Gas Composition of a Fluidized Bed Gasifier in a Sugarcane Bagasse-Modeling

Abstract

The assessment of the performance of various biomass fuel sources in gasifier is a significant zone of study for the execution of this innovation in different applications, pertinent to remote villages. This paper reveals the prediction of the composition of producer gas in a fluidized bed gasifier using Sugarcane Bagasse as feedstock where air to be used as gasifying agent. The model dependent on equilibrium constant and material balance has been created to assess the syngas compositions. The developed model has been used to predict the composition of constituent gases by varying equivalence ratio (ER) between 0.1 and 0.35 and keeping the moisture content (MC) constant. The outcomes show that the mole portion of CO from sugarcane bagasse is higher as compared to rice husk and coir pith and the composition of H2 and CH4 where absorbed very close to rice husk. Hence it recommended that the sugarcane bagasse and coir pith shall replace the rice husk and coir pith in fluidized bed gasifier for rural applications.
