EPA industrial boiler FGD (flue gas desulfurization) survey - 1979. Annual report, March 1980-March 1981

Technical Report ·
OSTI ID:5876807
The report gives results of a survey of vendors and operators of flue gas desulfurization (FGD) systems applied to industrial boilers for the 1979 calendar year. A total of 123 FGD units were operated throughout 1979. Once-through sodium systems accounted for 102 of these units, of which 74 were applied to small oil-fired steam generators in the California oil fields. The second most prevalent FGD process was the dual alkali system typically used on large coal-fired boilers, primarily in Illinois and Ohio. In addition, there were 98 planned industrial boiler FGD units, most of which are once-through sodium systems applied to oil-field steam generators. The performance data (SO/sub 2/ removal) for once-through sodium units is high, with all reporting systems achieving greater than 95% removal. The lime/limestone units achieved 85 to 92% SO/sub 2/ removal. The dual alkali units averaged greater than 90% SO/sub 2/ removal. Reported reliability for FGD units at seven sites averaged about 95% with sodium systems generally achieving greater than and lime/limestone systems less than 95%.
