Analysis/control of in-bed tube erosion phenomena in the Fluidized Bed Combustion (FBC) system. Technical progress report, January 1, 1994--March 31, 1994
This technical report summarizes the research work performed and progress achieved during the period of January 1, 1994 to March 31, 1994. The metal wastage mechanisms and rate that occur in 1018 carbon steel used in in-bed tube of the bubbling fluidized bed combustor (BFBC) are discussed with particle-surface collision frequency around tube. The distribution of particle-surface collision frequency around tube was affected by the location of tube and bed height. A series of material wastage tests was carried out using 742 {mu}m, quartz silica (SiO{sub 2}) on 1018 steel at elevated temperature (300 {degrees}C) which occurs in-bed locations of BFBC. The morphologies of the specimens were examined and analyzed by scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). The maximum collision frequency around the periphery of the tube was found at 45 {degrees}, 315 {degrees} from bottom center, 0{degrees}, which was correlated with maximum material wastage rate of the specimens.
