Results are given of a survey of the wet limestone flue gas desulfurization (FGD) system at the La Cygne Station of Kansas City Power and Light Co. and Kansas Gas and Electric Co. The FGD system was built integral with the electric power generating facility. The system consists of seven modules for particulate and SO/sup 2/ removal, with on-site limestone grinding and storage facilities. Since there is no provision for bypassing flue gas around the FDG modules, all flue gases are treated. Several modifications were made since system start-up in February 1973. A particulate removal efficiency of 97 to 99% was reported. SO/sup 2/ removal efficiency ranges between 70 and 83%. The spent limestone slurry is discharged to a 160 acre pond, and water from the pond is recycled. The initial installed capital cost of the FGD system was $34 million or $41/kW (based on a net rated capacity of 820 MW) in 1973. Subsequent modifications increased the cost to about $45 million or $55 KW. Estimated operating and maintenance cost, including limestone, are 1.79 mills/kWh, not including capital charges.
