Bull Run Fossil Plant
What TVA is doing about emissions at Bull Run
TVA has taken a number of steps to make the efficient generation of power at Bull Run as clean as possible:
- The use of low-sulfur coal from eastern Kentucky reduces emissions of sulfur dioxide.
- A scrubber that began operating in December 2008 is further reducing sulfur dioxide emissions by 95 percent.
- The plant is equipped with electrostatic precipitators that capture ash from the burning coal.
- Boiler optimization controls, which burn the coal more thoroughly and efficiently, limit the production of nitrogen oxides.
- A selective catalytic reduction system further reduces nitrogen oxide emissions by about 90 percent.
