Development of the instrumentation and modeling for heat transfer characteristics in CFBC. Semi-annual report, September 30, 1996--March 29, 1997

PDF Version Also Available for Download.

Description

The system tests were conducted by the bench-scale CFB system. Pressure drops of the distributor plate and the cyclone were measured. Tests conducted without the feeding solids into the CFB riser were analyzed. The primary air flow rate was measured by the specially designed pitot tube. The air flow rate was a function of the pressure drop. Tests were also conducted with feeding solids into the rider under different primary air flow rate. The solid feed rate increased as the aeration flow rate increased. The void fraction was reduced with an increasing pressure drop in the CFB riser column. The ... continued below

Description

The system tests were conducted by the bench-scale CFB system. Pressure drops of the distributor plate and the cyclone were measured. Tests conducted without the feeding solids into the CFB riser were analyzed. The primary air flow rate was measured by the specially designed pitot tube. The air flow rate was a function of the pressure drop. Tests were also conducted with feeding solids into the rider under different primary air flow rate. The solid feed rate increased as the aeration flow rate increased. The void fraction was reduced with an increasing pressure drop in the CFB riser column. The millet particles were tested by the modified CFB system. The computer-assisted data acquisition system was developed to measure the pressure of different locations along the riser wall. Seven pressure transducers were connected to the pressure taps on the riser wall. Before using the pressure transducers, each transducer was carefully calibrated by the specially designed pressure calibration system. The aeration flow rate was adjusted to change the solid feed rate. The differential pressures were recorded by the data acquisition system. The pressure drop along the riser column was the function of the riser column height. The pressure drop decreased as the riser column height increased.
