No sulfur oxide pollution control system is universally applicable. Flue gas desulfurization units appear to be most appropriate for large boilers that can operate compatibly with FGD systems at high load factors throughout most of their life. In contrast, solvent-refined coal is most appropriate for medium to small boiler units where load factors over the life of the plant are expected to be less than 65 percent, or where it is desirable to dedicate a utility's capital to electric generating equipment. As a corollary, SRC would be appropriate as the clean fuel in an intermittent control system (ICS) plan. SRC would be burned only during poor meteorological conditions that occur about 10 percent of the time during the year. Thus, ICS is tantamount to SRC being burned at low load factor; and considerable savings in sulfur oxide emission control costs are possible without jeopardizing ambient air quality standards. The use of low sulfur western coal appears economically feasible as a sulfur control method for some plants within a range of 1200 miles. The zone of equal trade-off appears to be located near the Mississippi River.
