| Abstract | A bubbling fluidized bed gasifier model was developed to investigate the hydrodynamic behavior inside bed zone at an elevated temperature. Compared to the behavior under ambient temperature condition, the pressure drop across the bed resulted from the simulation at elevated temperature, i.e. 800?C, was lower and the bubbles formed rose to the bed surface faster. The main reasons were the decrease in air density and dynamic pressure with increasing temperature. |
