Title: Fluidized-bed waste-heat recovery system development. Semiannual report, August 1, 1983-January 31, 1984

Technical Report ·
OSTI ID:6122237

A major energy loss in industry is the heat content of the flue gases from industrial process heaters. One effective way to utilize this energy, which is applicable to all processes, is to preheat the combustion air for the process heater. Although recuperators are available to preheat this air when the flue gases are clean, recuperators to recover the heat from dirty and corrosive flue gases do not exist. The Fluidized-Bed Waste-Heat Recovery (FBWHR) System is designed to preheat this combustion air using the heat available in dirty flue gas streams. In this system, a recirculating medium is heated by the flue gas in the fluidized bed. The hot medium is then removed from the bed and placed in a second fluidized bed where it is fluidized by the combustion air. Through this process, the combustion air is heated. The cooled medium is then returned to the first bed. Initial development of this concept is for the aluminum smelting industry. In this report, the accomplishments of the preceding six-month period are described. Specifically, long duration field testing of distributor plates and on-line cleaning were conducted, as well as startup and initial testing of the laboratory test facility. 39 figures, 2 tables.
