Volume II of this report contains technical support data, references to support the operating performance estimates, detailed descriptions of cost estimating methodologies, and the computer design model for the Staged Cascading Fluidized Bed Combustor (SCFBC). The primary issues dealt with in this volume are: fuel burnout efficiency; sulfur capture efficiency and in-line sorbent reactivation; bed to boiler tube heat transfer coefficients; NO/sub x/ and CO emissions; design considerations for downcomers; selection of coal feed systems; and capital cost estimating methods. The design options of the SCFBC boiler are discussed in terms of the technical suport data. In particular, the selection of stage temperatures, stage bed depths, and boiler tube arrangements in beds are presented so as to minimize the capital and operating costs of the plants designed. Capital cost estimating for the boiler and balance of plant components are discussed in some detail. Finally, an outline of the flow logic for the computer design program is presented in this volume. This program incorporates the kinetics of carbon burnout, sulfur capture, and heat transfer, while maintaining strict adherence to mass and energy balances on the fire side and steam side of the boiler on a stage-by-stage basis. The model is based on the original SCFBC design and provides the basis for design optimization and performance and cost estimates. The process design outputs from the computer program are presented.
