Gasification of Pine Wood Chips with Air-Steam in Fluidized Bed - Najdat Salami - Bog

This work has studied the impact of gasification mediums (air and steam air mixture) on syngas components (H2, CO) and low heating value LHV. This study has been based on previous research and experimental studies conducted in fluidized bed by using air-stream as gasification agent and pine wood chips as feed stock. According to the results of the experiments and discussion, it has been found, that the gas quality is improved with the use of the steam and air mixture. The parameters, with which to achieve the best quality of the produced gas at experimental conditions: (ER = 29, Tf1 = 261 °C) are as follows: T101 = 829 °C, S/B=0.67, where hydrogen is increased from 10.48 to 19.68 % and low heating value from 3.99 to 5.53 MJ m¿3 and tar is decreased from 1964 to 1046 mg m¿3 by increasing S/B from 0 to 0.67 at T101 = 829 °C.
