The primary purpose of the DOE extension testing, which began in April 1990, was to demonstrate the generic applicability of Limestone Injection Multistage Burner (LIMB) technology. The program sought to characterize the SO{sub 2} emissions that result when various calcium-based sorbents are injected into the furnace, while burning coals with a range of sulfur content from 1.6 to 3.8 percent. The four sorbents used included calcitic limestone, dolomitic hydrated lime, calcitic hydrated lime, and calcitic hydrated lime with a small amount of added calcium lignosulfonate. The initial EPA program focused on tests with the calcitic hydrated lime while burning a 3.0 percent sulfur Ohio coal. Tests with the lignosulfonate-doped material were added after pilot tests appeared to show enhanced reactivity. The results presented for the various coal/sorbent combinations include further characterization of the SO{sub 2} removal to be expected with and without humidification to a close approach to saturation, the effects of limestone particle size distribution, and the effects of injection at different elevations in the furnace. NO{sub x} emissions are also presented since the bioler operated with low-NO{sub x} burners throughout all the tests. The burners were installed as part of the original LIMB demonstration.
