System analysis of fluidized-bed combustor, Naval Base, Great Lakes
A semi-commercial size fluidized bed combustor for burning coal in the presence of limestone has been designed and built at the Great Lakes Naval Training Center. UOP/SDC has been requested to perform a systems analysis of the feed system, the fluidized-bed combustor, and the flue gas path components to determine their operability, safety, and reliability and also to make a failure mode and effects analysis. Information for this study was gathered from review of selected drawings and from discussions with the designer (Combustion Engineering) and the design reviewer (Davy McKee). Systems analysis of the FBC-System revealed no abnormalities. The basic design features were reviewed, and the findings were satisfactory. The system has been well instrumented and should provide adequate safeguards. The problems of feed splitting in the desired ratio could not be evaluated, as the necessary data and the detailed design were proprietary in nature, and UOP/SDC did not have access to that information. Fluid bed slumping for partial operations was modeled. Two interesting features on side drifting were found: the drift depends upon the fluidization velocity and the solids diffusivity; and the drift profile is approximately exponential.
