Melton Valley Steam Plant

Oak Ridge, Tennessee

ESG provided the design and commissioning of this new steam plant for Oak Ridge National Laboratories in Oak Ridge, Tennessee. This project consisted of (1) 150 PSI, 300HP Cleaver Brooks Fire Tube Super Boiler and (3) 150 PSI, 100 HP back-up Miura Water Tube boilers. This project included a reverse osmosis water treatment system for boiler make-up water. This high efficiency super boiler will be the primary boiler and is fired on natural gas only. The back-up Miura Boilers will be fired on natural gas and fuel oil. This allows for continued interruptible gas service for ORNL.

Back-up systems were required for this project and include a 10,000-gallon fuel oil tank, a 15,000-gallon storage tank for RO make-up water, and a 400kW diesel generator. The complete system is controlled by Johnson Control Matasys DDC system with a Cleaver Brooks Hawk integrated control system.

The project was fully commissioned and completed on August 6, 2010.
