|
Summary :
|
|
THIS WORK PRESENTS A SIMPLIFIED MATHEMATICAL MODEL OF A SHALLOW FLUIDIZED BED HEAT EXCHANGER WITH IMMERSED TUBES. THE THERMAL PERFORMANCE OF THE EQUIPMENT IS OBTAINED FOR A COUNTER FLOW HEAT EXCHANGER WITH WATER FLOWING INSIDE THE TUBES AND THE SOLID-GAS SUSPENSION OUTSIDE THEM. THE FLUIDIZED BED IS DIVIDED IN STAGES ALONG THE LONGITUDINAL DIRECTION WHERE THE HEAT AND MASS BALANCES AMONG THE THREE CURRENTS INVOLVED (SAND PARTICLES, AIR AND WATER) ARE CONSIDERED. THE PREDICTED MODEL TEMPERATURE PROFILE ALONG THE LENGTH OF THE EQUIPMENT PRESENT GOOD AGREEMENT WITH EXPERIMENTAL DATA WITH A MAXIMUM DEVIATION OF 25%. |
