Laseke, B. AND Jr. SURVEY OF FLUE GAS DESULFURIZATION SYSTEMS: LA CYGNE STATION, KANSAS CITY POWER AND LIGHT CO. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/7-78/048D.
Description:
The report gives results of a second survey of the flue gas desulfurization (FGD) system on Unit 1 of Kansas City Power and Light Co.'s La Cygne Station. The FGD system, first started up in February 1973 and commercially available in June 1973, uses a limestone slurry in eight scrubbing modules to control fly ash and SO2 from the combustion of high sulfur subbituminous coal. Each module includes a venturi scrubber, sump, and two-stage sieve tray absorber. All the flue gas is treated: it cannot bypass the scrubbing modules. Facilities for limestone grinding and storage and final disposal of the flue gas cleaning wastes are on the plant grounds. Clear water is recycled from the pond to the FGD system for additional use. SO2 and particulate removal efficiency measurements indicate that the design values of 80 and 98.75%, respectively, have been met or exceeded.
