Steam Plant Conversion to Natural Gas

Knoxville, TN

Two 100,000 lb/hr coal-fired boilers were replaced with new 99 MMBTU input gas-fired boilers with fuel oil back up in the Steam Plant serving the UT Knoxville campus.  All existing coal and ash handling equipment and the existing 300-foot-tall stack were removed.  Additional fuel oil storage of 150,000 gallons was provided with multiple tanks at the site. Fuel oil is delivered by truck.  The plant water treatment train was relocated and improved.  Switchgear was added to the 2 MW diesel generator to permit operation in parallel with the 5 MW natural gas turbine generator.  Other improvements included replacement of windows in the plant, a screen wall around the existing diesel generator, and site lighting improvements and landscaping. Upgrade of the existing 5 MW turbine generator controls was included.  The schedule for the project required the plant be in operation during some portions of the construction.

ICT provided mechanical, electrical and controls design for the steam plant conversion to natural gas.
