Abstract
This paper gives results of estimating performance/costs of retrofitting pollution-control technologies at 12 coal-fired power plants. In cooperation with the states of Ohio and Kentucky (in conjunction with EPA's state acid-rain program), efforts were undertaken to visit and conduct detailed evaluations of 12 coal-fired plants--5 in Ohio and 7 in Kentucky and the Tennessee Valley Authority system. A variety of commercial and advanced SO/sub 2/ and NOx control technologies--including precombustion, combustion (in-furnace, and post-combustion (flue gas cleanup) technologies--were applied to each plant through conceptual designs. Retrofit factors (applied to the capital cost of a new pollution control system), cost adders (e.g., movement of existing equipment), and costs were developed for applying the control technologies to the boilers of each plant. Results of these and subsequent efforts will be valuable in evaluations of acid deposition control strategies by federal and state agencies and by electric utilities.
