What TVA is doing about emissions at Paradise
TVA has taken a number of steps to make the efficient generation of power at Paradise as clean as possible:
- Wet limestone scrubbers remove 80 to 84 percent of the sulfur dioxide (SO2) from emissions at Paradise Units 1 and 2. A scrubber is being installed on Unit 3 that is scheduled for completion in 2006.
- Unit 3 burns low-sulfur coal to limit SO2 emissions.
- A technology called overfire air limits the production of nitrogen oxides (NOx), which contribute to the formation of ozone and acid rain. This technology involves modifications that reduce the oxygen available to form NOxin the furnaces’ combustion zones.
- Paradise Unit 2 was the first fossil unit in the TVA system to be equipped with a selective catalytic reduction (SCR) system, which reduces NOxemissions by transforming them into harmless nitrogen and water vapor. All three Paradise units are now equipped with this technology.
