The report describes the design, construction, and installation of a fluidized-bed coal combustion sampling and analytical test rig in the High Bay Area (Wing G) of EPA's Industrial Environmental Research Laboratory (IERL), Research Triangle Park, North Carolina. The rig, to be used by IERL to investigate the emission characteristics of fluidized-bed combustors, was designed for maximum flexibility, accuracy, and utility. System operating ranges are: coal feedrate--10 to 50 kg/hr; sorbent feedrate--zero to 25 kg/hr; excess air--10 to 300%; bed temperature--750 to 1100C; and fluidizing velocity--1 to 5 mps. The program included four phases: conceptual design; final design; purchase, fabrication, and installation; and checkout, testing, and documentation. After installation, an acceptance test demonstrated that the system had been completed in accordance with the approved design, and that all equipment was properly installed and corrected to serve its intended purpose.
