Development of the instrumentation and modeling for heat transfer characteristics in CFBC
This technical report summarizes the research performed and progress achieved during the period of October 1, 1995 to March 31, 1996. The bench-scale circulating fluidized bed (CFB) system was carefully designed and fabricated to study gas/particle flow and heat transfer characteristics on the wall of the CFB riser. Design and fabrication of the major components such as gas distributor, cyclone, wind box, surge tank, solid control valve, and riser were summarized in this report. The air supply subsystems including blower, control valve, PVC piping, and air flow measuring devices are arranged and described. The advanced data acquisition system and instrumentation will be developed/applied to measure pressure change along the CFB riser height, gas/particle velocities, local heat transfer coefficient on the wall of CFB, and mass flux of the solid particles. The heat transfer probe will be designed to measure the bed-surface heat transfer coefficient on the wall of the CFB riser. In addition, an electrostatic probe will be designed to measure the local mass flux of the solid particles in the CFB. The progress of this project has been on schedule. The arrangement of the auxiliary subsystems for the bench-scale CFB will be completed for the system test. 4 refs., 6 figs.
