This two-volume report, which is generated by a computerized data base system, represents a survey of operational and planned domestic utility flue gas desulfurization (FGD) systems. It summarizes information contributed by the utility industry, system and equipment suppliers, system designers, research organizations, and regulatory agencies. The data cover system design, fuel characteristics, operating history, and actual system performance.^Also included is a unit-by-unit discussion of problems and solutions associated with the boilers, scrubbers, and FGD systems. Along with the design and performance data for operational FGD systems contained in Section 3, this report also presents tabulations of some of the key data. The Executive Summary contains the number and capacity of FGD systems as of the end of March 1983, future (December 1991) projections of controlled and uncontrolled generating capacity, and unit-by-unit summaries of status changes (e.g., contract awarded, under construction, or operational) and performance (problems/solutions/comments) during the period. Simplified process flow diagrams of FGD systems, definitions, and a glossary of terms are attached to the report. Current data for domestic FGD systems show 106 systems in operation, 35 systems under construction, and 70 systems planned.The current FGD-controlled capacity in the United States is 41,894 MW.
