| Abstract |
The reaction of SO2 with limestones, dolomites, and limes was studied under simulated boiler conditions with the dispersed-phase reactor. This reactor provides for injection of limes or stones into a flue-gas stream. As in the case of injection into a power boiler, the particles are dispersed in the gas; also, as in a boiler, the samples are near room temperature when injected, and must heat up (and calcine in the case of raw stones) before reacting with the SO2 present. Conditions differ from those in a boiler in that the walls are kept hot to maintain relatively constant gas temperature, and the samples are small compared with the amount of gas so that the SO2 level remains essentially constant. The results of the current work provide at least a qualitative understanding of the overall reaction trajectory of the limestone-SO2 reaction and a possible connection between the results of the relatively long-term experiments carried by others and the short-term exposure in the dispersed-phase reactor or in a boiler.
