Once Tboiler

Steam For Power and Process

Designed for pulverized coal, B&W's advanced once-through ultra-supercritical boilers are usually applied to systems with a capacity of 400 MW or more. These clean and efficient boilers usually operate at throttle pressures of 3500 psi (24.1 MPa) or more and steam temperatures in the 1100F (595C) range.

Why Once Through Boiler

The fire tube boiler will run both units (12 ton/h) while Once Through Boiler will run three units (9 ton/h) and have the fourth unit available as required. Since Once Through Boiler can operate from a cold back-up, (water to steam in 5 minutes, while the fire tube boiler can take hours), the fourth unit can be idle until needed.


Planners created a vantage point for people to view the turbine room and created a spacious overlook balcony, which was copied at future plants. Though the steam plant was demolished in 2011, the Watts Bar reservation still contains a dam and a nuclear plant, and was once the only TVA site to feature three types of generation.
