Analysis/control of in-bed tube erosion phenomena in the fluidized bed combustion (FBC) system. Technical progress report No. 9, [October 1, 1994--December 31, 1994]
This technical report summarizes the research work performed and progress achieved during the period of October 1, 1994 to December 31, 1994. The characteristics of anti-erosion remedies and mechanism for in-bed in FBC were discussed to provide the basic design guidelines for anti-erosion devices. One of the anti-erosion remedies currently operate the basic principle of creating a protective stagnant layer of solids to against incoming high velocity of solid particles. This stagnant layer of solid is goal of breaking up the local flow patterns at eroding tube surfaces. This principle is embodied by designing of antierosion studs, pins, fins, and baffles. By attaching a number of studs with a sufficient stud-to-stud distance to avoid the bridging of solid particles, tube wastage can be retarded to prolong the boiler tube life. These devices will be used for the measurement of material wastage in the laboratory-scale FBC.
