Biomass Gasification in a Bubbling Fluidized Bed Reactor

Abstract

The effect of secondary airflow rate and particle size on the combustion temperature inside a bubbling fluidized bed reactor were reviewed. The experiments were carried out for four-particle sizes with different secondary airflow rates. From the results, it was evident that the secondary airflow rate has a more substantial impact on the temperature of the freeboard zone. The temperature profiles show that the maximum temperature is achievable when the magnitude of secondary airflow rate is lower than that of the primary airflow rate. It was concluded that the desired maximum temperature could be achieved regardless of the particle size through the optimum secondary airflow rates.
