Air pollution control technologies
By using a variety of proven technologies, Tampa Electric is significantly reducing oxides of nitrogen (NOx), particulate matter and sulfur dioxide emissions from Big Bend Station. Actions include:
- Combustion modifications to all four units and evaluation of the effects of each modification on NOx emissions. By 2010, NOx emissions from Big Bend Station will be reduced by over 89 percent from 1998 emission levels.
- Optimizing the electrostatic precipitators to minimize emissions of particulate matter from the stacks. By end of 2004, all improvements will be implemented, resulting in a reduction of approximately 59 percent when compared to 1998 levels.
- Further reduction of sulfur dioxide emissions by investing more than $23 million in scrubber upgrades, resulting in a reduction of over 87 percent from 1998 levels. During the scrubbing process, coal combustion gases are sprayed with a mixture of water and limestone. Sulfur oxides react with the spray to form gypsum, most of which is recycled.
Big Bend Power Station meets strict environmental guidelines.
