Gasification of Juliflora Chips in a ...

Gasification of Juliflora chips was carried out in a 0.156 m inner diameter and 5 m height circulating fluidized bed gasifier with sand of 250 μm diameter as the bed material and air as the fluidizing medium. The influence of equivalence ratio and gasification temperature on gas composition, gas yield, lower heating value and gasification efficiency was investigated. The gasification temperature and equivalence ratio were maintained in the range of 700 to 900oC and 0.2 to 0.3 respectively. Equivalence ratio and temperature strongly influenced the gas composition. With an increase in equivalence ratio, the temperature and gas yield were increased decreasing the gas heating value. It was also observed that the increase of temperature also increases the gas heating value, gas yield and gasification efficiency. Comparison of present experimental data with findings of other studies of different biomass fuels is also discussed in this paper.
