Site work and renovation of a power facility in Ames, Iowa. Design plans call for the renovation of a power facility.

This project is to replace the tubing in the superheats section of the unit 8 boiler. After switching from coal to natural gas, the tubes were found to be degrading much faster than anticipated. The high moisture created during the combustion of natural gas combined with chlorides and acidic gases from RDF combustion cause the metal tube surface to corrode very quickly. The current superheat tube thicknesses have been dramatically reduced and need to be replaced. An Inconel coating will be added to the new tubes to help them stand-up-to the harsh environment. Project is included City of Ames FY 2019-2024 CIP Page 69 _______________________________________________________________________________________________________________________ This project is to replace the tubing in the superheats section of the unit 8 boiler.
