Abstract |
The report gives results of physical and chemical characterizations of samples of spent bed material and of flyash from three experimental atmospheric and pressurized fluidized-bed combustion (FBC) units. It also gives results of characterization of samples of bed material which had been subjected to sorbent regeneration. In general, it was found that the granular material consists of three shells or zones. The outer zone, primarily CaSO4, is 2-25 micrometers thick; an intermediate zone, CaSO4 and soft-burned CaO, is 60-150 micrometers thick; and the third zone, in the center of the particle (for samples with incomplete sulfation), is primarily original absorbent. Particle size analysis shows that, in general, CaSO4 and Ca(OH)2 concentration increases as the size of the particle decreases and that CaCO3 is more concentrated in the larger fraction. The FBC residue was found to stabilize sludges produced by wet lime/limestone scrubber systems so that they would not soften when contacting water. |
