This report gives results of a survey of operational flue gas desulfurization (FGD) systems on coal-fired utility boilers in the United States. The FGD systems installed on Units 1 and 2 at the Sherburne County Generating Station of the Northern States Power Company is described in terms of design and performance. Each unit is equipped with an alkaline fly ash/limestone two-stage wet scrubbing system for the control of particulate and sulfur dioxide. Each FGD system includes 12 modules, 11 of which are required for full-load operation. The flue gas cleaning wastes are forcibly oxidized, concentrated in a thickener, and discharged for final disposal in a plant-site clay-lined settling pond. The Sherburne 1 and 2 systems were certified commercial on May 1, 1976 and April 1, 1977 respectively. Operation has been accompanied by a number of problems, most of which have been or are being resolved through system design modifications. Designed for a minimum availability of 90%, the modifications have increased availabilities to the low to mid 90 percent range. The systems have demonstrated compliance with particulate and sulfur dioxide emission regulations.
