Masoneilan 78400/18400 Series LincolnLog™ in a Combined-Cycle Power Plant
For well over a century, Masoneilan has been a leader in innovation, technology, and responsiveness to market needs. With its breadth of products and services, Masoneilan is uniquely positioned to be the leading provider of severe service valves. Their valve offering covers a wide range of different applications within various industries – including combined-cycle power plants.
Where Would Masoneilan’s LincolnLog™ be in a CCPP?
A combined-cycle power plant uses both a gas and a steam turbine together to produce up to 50 percent more electricity from the same fuel than a traditional simple-cycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power.
In the start-up process in a combined-cycle power plant, there is an extremely high pressure-drop – causing cavitation. Even though there can be start-up valves installed with cavitation containment, they are still ineffective and can experience an immense amount of cavitation damage throughout the process. Often the valve trim replacement in these valves is factored into a maintenance plan every six months.
How does Masoneilan’s LincolnLog™ Improve a CCPP?
With Masoneilan’s innovative LincolnLog™ anti-cavitation valve, many of Eastern Controls’ customers have seen a tremendous decrease in the amount of cavitation within their combined-cycle plant process. The LincolnLog™ utilizes a tortuous path to distribute pressure drop (the cause of cavitation) along the axis of the plug. The axial stages throttle in unison as the plug strokes, maintaining staging ratios at all lift points. The velocity and pressure drop are controlled, effectively eliminating any cavitation and resulting trim damage. The installation of a LincolnLog™ will reduce your plant’s maintenance downtime planned for the trim replacement you’re probably used to.
Additional benefits of the LincolnLog™ include:
- Protected soft seat offers long-term, reliable class VI shutoff capabilities, preventing loss of product
- Trim overlap protects the valve’s seating area from high-velocity flow, maintaining shutoff and preventing loss of product – boosting your revenue
- Multi-stage trim eliminates cavitation, offering a longer installed trim life
