This paper discusses the design, operation and emissions performance of a 70,000-lb/h coal-fired fluidized-bed combustor (FBC). The FBC is a novel dual-bed design that enables it to achieve high desulfurizing efficiencies in a short (14 ft. tall) package unit. Topics considered include the dual-bed package boiler, the improved coal feed system, the controls, retrofit capability, and current status. The FBC was installed at the Iowa Beef Processor's, Inc., plant in Texas. In 300 hours of round-the-clock testing, the FBC has demonstrated an availability of 98%. The gaseous emission levels were low, with CO, SO2 and NOx emissions at 100, 50 and 100 ppm respectively as the burner operated at 20% excess air. It is emphasized that FBC's must be designed to meet the requirements of retrofit, including a remote coal handling system (for use in buildup areas), a sufficiently compact boiler (to fit in the existing boilerhouse), and a water circulation system that allows the FBC to operate in conjunction with the existing boiler.
