This paper describes the Tennessee Valley Authority's (TVA) experience with flue gas purification equipment on coal-fired power plants. TVA's experience encompasses mechanical collectors, electrostatic precipitators, baghouses, wet limestone scrubbers, and atmospheric fluidized bed combustion (AFBC). Air pollution control at TVA facilities originally consisted of mechanical fly ash collectors which were installed primarily for equipment protection. Following a Presidential Executive Order and subsequent passage of the Clean Air Act, TVA's air pollution control measures for particulates and SO/sub 2/ increased dramatically. The addition of precipitators, baghouses, SO/sub 2/ scrubbers, and use of low-sulfur coal and coal-washing plants has significantly reduced emissions from TVA's coal-fired plants. Since 1977, TVA has achieved reductions of approximately 93% in particulate emissions and 50% in sulfur dioxide emissions. TVA is currently pursuing two new promising technologies for utility flue gas pollution control through a 160-MW AFBC demonstration project and a 160-MW dry flue gas desulfurization (FGD) project. 2 figs., 2 tabs.
