| Abstract |
The fluidized solid particles not only increase heat transfer rates but have a cleaning function eliminating contaiminated substances caused from condensate water. An experiment was performed to measure heat transfer rates and pressure drops in a fluidized heat exchanger with circulating solid particle for constant heat transfer rate. As a results, the heat transfer rate increased by 26.9∼2.6%, heat transfer coefficient by 11.9∼2.7%, and pressure drop by 79.1∼10.9% at the gas velocity of 6.1∼12.1 m/s and solid particle flow rate of 100∼50 kg/h with the heat exchanger of H＝50 mm, Dp＝2 in, and DBP＝30 mm. |
