OSTI ID:6426384
Oak Ridge National Laboratory (ORNL) has been involved for the past several years in the assessment, design and development of fluidized bed combustors. The current effort includes a development program for an AFBC-gas turbine industrial cogeneration plant, a PFBC utility plant assessment and design study, and technical and development support for the TVA Pilot Plant program. The FBC experience and R and D capabilities of ORNL complement the power plant design, construction and operating experience of TVA in the AFBC Pilot Plant program. The technical support provided by ORNL includes a number of analytical and experimental tasks in several area of AFBC technology. The major development effort has been in the areas of combustion performance and coal feeding. Sulfur capture performance data have been obtained in the ORNL Bench Scale Combustor for candidate limestones with once-through feeding and with fines recycle. The target performance of 90% SO/sub 2/ retention was achieved with a Ca/S mole ratio of 2.1 with fines recycle. A fundamental test program on the pneumatic transport of coal and coal-limestone mixtures was conducted to investigate the influence of particle size distribution, surface moisture and transport velocity, on pressure drop, saltation and plugging.
