Agriculture waste used on the working parameters of fluidized gasification

Abstract

The objective of the present work was to assess the agro-industrial residuals in a fluidized bed gasification process. The experiments were performed in a pilot scale auto-thermal fluidized bed gasifier (FBR) were wheat husk, rice husk and corn stalk was used as the feed stock after analyzing phsio-chemical analysis with physical pre-treatment by using air as gasifying agent. The working parametric such as bed temperature (t), equivalence ratio (e), pressure (p), feed size (fs) and fuel consumption rate (fc) with optimum condition considered to improve producer gas efficiency, tar yield efficiency and ash content efficiency. Experiments were conducted between the ‘t’ range of 650-900°C, using ‘e’ ranges 0.2 to 0.35, ‘fs’ between of 75 to 300 μm and ‘fc’ range of 5 to 20 kg/hr. In the present investigation, an empirical relationship was developed to predict the process of generating producer gas with better quality through gasification of biomass in a FBR using response surface methodology (RSM). The full potentiality of wheat husk, rice husk and saw dust for gasification was investigated via RSM. Higher fs and e resulted in more gas yield due to increases in the exothermic reactions. The developed model was made a good prediction for the experimental data as well as predicated data.
