The purpose of this study is to determine the feasibility of dry-type desulfurization process for actual application tocoal-fired power plant. We used actual exhaust gas from Facility Y, Plant #2 to fabricate a demo-scale testing deviceto attempt to improve the efficiency of desulfurization. A spout-bed circulating dry scrubber convergence systemconnecting turbo reactor with bag filter was devised, then analyzed for performance characteristics of SO2 removal forCa/S mole ratio, superficial gas velocity, and ammonia injection, and for secondary reaction characteristics of thenon-reactive sorbent at the bag filter. As a result, the installation of spout-bed circulating dry scrubber convergencesystem showed better economy and efficiency for removing sulfur than the existing wet/semidry-type desulfurizationprocess. In addition, the best efficiency for desulfurization occurred when connected to the bag filter, with differentialpressure maintained at 150 mmH2O.
