Atmospheric fluidized-bed combustion development facility. Final report
The objectives of this project were to design, construct, and commission an atmospheric fluidized-bed combustion (AFBC) test facility capable of: producing performance data suitable for scale-up to utility-size units; evaluating changes to the process relative to improving performance or reducing cost; and providing data that could be used as a base for design correlations. A bed size of 6 feet x 6 feet was selected as being large enough to bridge the gap between bench-scale units and commercial units. This size enabled use of multiple coal feeds at state-of-the-art spacing. Sufficient instrumentation was installed for accurate measurement of parameters identified as required for performance data. These parameters included: coal and limestone feed rate, ash removal rate, forced-draft air flow, temperatures and pressures throughout the unit, gas composition at various locations, and others. The 6 x 6 AFBC was constructed with sufficient flexibility to allow future design changes. Selection of equipment (e.g., coal feeder, conveyors, etc.) was based partially on price and delivery, but mainly on reliability and the capability for long-term, continuous operation. The 6 x 6 will be the major AFBC test facility to develop performance data for the commercial development of AFBC. Specifically, it will aid in design correlation development, in the application of these correlations to utility conceptual design studies including economic assessments, and in forming the basis for scale-up for larger pilot and demonstration AFBC units.
