The increasing worldwide recognition of the need to control emissions of the harmful flue gas constituents from the combustion of coal and other fossil fuels is resulting in a considerable demand for lower cost air pollution control equipment. The need is felt not only in the United States, with its large existing capacity of older power plants equipped to burn high-sulfur coal, and in Europe, but in third world countries where new lower-capital-cost power plants are needed to meet the growth in energy consumption. In the United States, as we approach the nominal, Year 2000, Phase II deadlines of the 1990 CAAA, decisions must be made as to the future status of the large number of older, smaller sized, high-sulfur burning plants. The options include switching to low sulfur coal, shutting down, or finding an economical alternative to selection of wet scrubbing. A continuation of the shift to the use of low sulfur coal that was undertaken during Phase I to meet the 2.5 lbs/mmBtu SO{sub 2} limit is not the answer. Lower sulfur coal will not meet the 1.2 lbs/mmBtu limit of Phase II in lieu of post combustion desulfurization. In addition, the increase in the cost of low sulfur coal that will result from continued coal switching will tip the balance in favor of seeking a low cost means of utilizing high sulfur coal.
