| Abstract | This report presents the results of an experimental study of combustion, gasification and heat transfer in both conventional and pulsed fluidized bed. Experimental studies on combustion, gasification and heat transfer in both conventional and pulsed fluidized bed were conducted using silica sand at size of 425-600 micron as the bed material. The pulsation was conducted by an air chopping machine. The experimental works on combustion and gasification were carried out with variation of equivalence ratio, bed temperature and pulsation frequency. The study on heat transfer in hot bed was conducted with variation of superficial air velocity and pulsation frequency. With pulsation, the results show no effect on the performance of both fluidized bed combustor and fluidized bed gasifier when compared with the results of normal air supply. The study of heat transfer, heat transfer coefficient between fluidized bed and immersed surface increased when using pulsation and the maximum increase of heat transfer coefficient was at pulsation frequency of 2 kHz. |
