Analysis/control of in-bed tube erosion phenomena in the fluidized bed combustion (FBC) system
This technical report summarizes the research work performed and progress achieved during the period of April 1, 1994 to June 30, 1994. The metal wastage tests were continued to understand the erosion phenomena of in-bed tube in FBC system. The plain carbon steel, AISI 1018 was used as the target materials along with quartz silica (SiO{sub 2}) as the erodent particles. For the high velocity test, the short exposure time (4 hours) minimized the oxide scale formation and potential weight gain. No oxidation layer could be seen on worn surfaces. The eroded surface of specimens tested under high particle velocity exhibited the typical ductile mode. The maximum material wastage was occurred at 45{degrees} of impact angle. The metal wastage rate of AISI 1018 carbon steel demonstrated higher wastage at a shallow angle than at a step angle with a maximum erosion rate occurring at impact angle of 45{degrees}. The morphologies of the specimens were examined and analyzed by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS).
