The importance of RTO maintenance
RTOs or Regenerative Thermal Oxidizers control emissions without producing harmful byproducts or hazardous waste. They help destroy volatile organic compounds (VOCs), hazardous air pollutants (HAPs) and other odorous emissions created during normal manufacturing and industrial processes by combusting them into carbon dioxide and water. RTOs pass hot exhaust gas and cooler

The Omaha Public Power District (OPPD) board of directors voted unanimously on June 16 to close Fort Calhoun Station, the smallest nuclear power plant in the U.S., due to economic reasons.
