This technical report summarizes the research conducted and progress achieved during the period of April 1, 1996 to September 30, 1996. Auxiliary subsystems tests of the circulating fluidized bed were conducted and included the characteristics of a regenerative blower, a gas distributor, and a cyclone. When the air flow rate increases, the pressure at the blower outlet is decreased. The air flow rate in the riser is a function of the pressure in the wind box. The cyclone pressure drop and gas distributor pressure drop are functions of the primary air flow rate input. The higher gas pressure drop indicates primary air in the riser column with a uniform superficial velocity. The CFB primary test was conducted using glass beads as one of the CFB bed materials. Three typical tests with different sizes of glass were conducted. The pressure sensor data acquisition system was developed for the systematic instrumentation of flow measurements in the CFB system. Two types of sensors were used, a single pressure sensor, and a differential pressure sensor, respectively. The software used to control the analog/digital board was Paragon 500. The CFB experimental studies for hydrodynamics will be continued with the improved data acquisition system
