Improved experimental equipment and analytical techniques have enabled more detailed study of the reaction between Limestone 2061 and SO2 in flue gas. Progress was made in analysis of results and development of techniques for prediction of performance of the process in a boiler by means of both empirical and theoretical evaluation of various aspects of the process. Results obtained for Limestone 2061 indicate: (1) maximum reactivity at injection temperatures not exceeding about 2200 F, (2) reduced sorption efficiency at low SO2 concentration, (3) possible improvement in the efficiency of the process at excess oxygen levels above 3 percent, and (4) reduced efficiency as a result of use of precalcined stone.
