Development of a high energy efficient pressure calciner. Final report, June 1, 1994--July 31, 1997

PDF Version Also Available for Download.

Description

During the life of this contract, the design, procurement, and construction of a pilot, self-fluidizing, pressure calciner for the production of smelting grade alumina was completed. Initial operating characteristics were determined, and the first half of the first DOX was completed. A design capacity of at least 100 kg/hr of product had been chosen to insure a 100:1 maximum scale-up ratio for the semi-commercial unit. Detailed numerical analysis was made for the heat exchanger design to set the active tube length at 8.5 m (28 ft). The instrumentation and data logging system was designed to obtain the detailed engineering parameters ... continued below

Description

During the life of this contract, the design, procurement, and construction of a pilot, self-fluidizing, pressure calciner for the production of smelting grade alumina was completed. Initial operating characteristics were determined, and the first half of the first DOX was completed. A design capacity of at least 100 kg/hr of product had been chosen to insure a 100:1 maximum scale-up ratio for the semi-commercial unit. Detailed numerical analysis was made for the heat exchanger design to set the active tube length at 8.5 m (28 ft). The instrumentation and data logging system was designed to obtain the detailed engineering parameters for design of the semi-commercial unit. The pressure feed, discharge, and burner systems were chosen from existing commercial designs to reduce the development work required. Auxiliary equipment, steam condenser, cooling tower, and product cooler, were chosen to simplify operation during the experimental program. Self-fluidizing capabilities were determined to exist both from temperature profiles and heat transfer coefficient calculations.
