An Experimental Study of Sunflower Husks Gasification in a Fluidised Bed

An experimental investigation of a fluidised bed gasifier was carried out using sunflower husks as combustible and air and steam as gasifying agents. The influences of excess air ratio and temperature on the composition of syngas produced are presented. In the present work, gasification temperature was varied from 700 to 850°C in 25°C increments, and was obtained an excess air ratio in the range of 0.18 to 0.41. It has been found that in the syngas obtained by fluidised bed gasification process, the molar fractions of N2 and CO increase with the increase in excess air ratio, while the molar fractions of CO2 and CH4 decrease. The content of H2 in the syngas increases with excess air ratio initially and then decreases with the increase in excess air ratio. The lower heating value of the syngas produced by sunflower husk was calculated from the concentration of the combustible components (CO, CH4, and H2). The lower heating value produced decreases initially and then increases with excess air ratio.
