Cedar Bay and CCI are on a Roll

Over the past few years, CCI and Cedar Bay have been working closely together to upgrade the cogeneration station’s severe service control valves and systems to maximize plant performance and efficiency. CCI’s recent projects with Cedar Bay include installation of a DRAG® 100DSV spraywater valve on a DAO desuperheater, a DRAG® vent valve and resistor on process steam, three DRAG® resistors on boiler blow-off steam, and a QuickTrak™ electronic valve actuator (see “Precision Pays off at Cedar Bay Cogen,” click here).

Now Cedar Bay has turned to CCI once again, this time to replace all three of its feedwater regulator stations with a high-capacity DRAG® solution. Feedwater regulators are responsible for controlling feedwater flow from the boiler feedpump to the drum based on boiler and turbine demand, and wrong water levels can result in plant trip or ruptured pipes. Difficulties with the power plant’s existing feedwater stations, each of which include a startup valve and a main valve, were causing Cedar Bay poor control and risky startup times.

The CCI solution is a single DRAG® valve combining a startup and main valve. Combining these two valves into one results in smoother control, higher rangeability from startup through full load, and lower cost of ownership. Additionally, CCI’s exclusive disk stack control element features a torturous path in which each of several right-angle turns reduces the flow pressure, resulting in exceptional velocity control at low flows and high delta pressures.

Offering precise flow control, high rangeability, and reduced plant startup time, CCI’s feedwater regulators will ensure superior plant efficiency and system reliability. With yet another high-quality, dependable CCI solution installed, Cedar Bay is rolling right along, its ongoing partnership with CCI providing peace of mind and continued performance gains.
