Description: In this quarter the design of the plant structures was completed 70%. The design philosophy of the structure economizes on the use of steel by providing supports for the hot cyclone and hot gas duct connecting the cyclone to the boiler while fulfilling the needs for platforms and walkways at the various levels necessary for operational access. Figures 1 through 6 indicate the layout of the plant structure. At the same time the structure for the Coarse Coal Silo V-2 and Limestone Silo V-4 were incorporated and completed. Following completion of the piping pressure drop calculations, pipe sizing and layout drawings, detailed drawings of the piping in different views are being prepared. The pulse combustor is used to burn fine coal particles and provide an ignition source and supplementary heat to the fluid bed. The following is a description of the components: air plenum, fine coal injectors, aerovalves, water jacket, and tailpipe inserts.
