The report gives results of an EPA-sponsored economic evaluation of three processes to reduce NOx, SO/sub 2/, and ash emissions from coal-fired utility power plants: one based on 3.5% sulfur eastern bituminous coal; and the other, on 0.7% sulfur western subbituminous coal. NOx control is based on an 80% reduction from current new source performance standards (NSPS); SO/sub 2/ and fly ash control are based on meeting the current NSPS. Selective catalytic reduction (SCR) is used for NOx control with both coals. Limestone scrubbing and a cold-side electrostatic precipitator (ESP) are used with the 3.5% sulfur coal. Lime spray dryer flue gas desulfurization (FGD) and a baghouse for particulate collection are used with one 0.7% sulfur coal; and limestone scrubbing and a hot-side ESP, with the other. The economics consist of detailed breakdowns of the capital investments and annual revenue requirements. The 3.5% sulfur coal case is highest because of the higher SO/sub 2/ control costs. The case with the spray dryer and baghouse is marginally lower in cost than that with limestone scrubbing and hot-side ESP. Costs for NOx control are 25 to 50% of the total costs.
