The report gives results of ana evaluation of the potential of furnace sorbent injection (FSI) for sulfur dioxide (SO2) emission control on coal-fired boilers burning coals indigenous to Illinois. Tests were run using four coals from the Illinois Basin and six calcium hydroxide (Ca(OH)2) sorbents, including one provided by the Illinois State Geological Survey (ISGS). The evaluation included pilot- and bench-scale sorbent reactivity testing, sorbent microstructure characterization, and injection ash characterization. Pilot-scale FSI testing gave SO2 removal greater than 60%, with some tests (including those with the ISGS sorbent) exceeding 70% removal for Ca/S ratios of 2:1. Bench-scale testing of injection at economizer temperatures (538 C) yielded comparable removals of about 55%. X-ray diffraction (XRD) tests of the sorbents showed a strong correlation between three measured crystallite microstructural parameters and sorbent reactivity in the FSI tests. Extraction procedure (EP) toxicity tests with the sorbent injection ash gave values well below Resource Conservation and Recovery Act (RCRA) limits for regulated metals.
