What is the flow path for lube oil from the 55# header to the Turbine Bearings?

The flow path for lube oil from the 55# header to the Turbine Bearings is accurately described by the flow sequence: Oil Cooler -> Duplex Strainer -> Supply Header.

Initially, lube oil is subjected to cooling for temperature regulation and to ensure optimal lubrication properties. The oil cooler plays a critical role by reducing the temperature of the lube oil before it enters the lubrication system.

Following the cooling process, the lube oil passes through a Duplex Strainer. This strainer is essential for filtering out contaminants and particulates that may be present in the oil, thereby protecting the turbine bearings. The use of a duplex strainer allows for maintenance without interrupting the flow of oil, as it can be switched to the second unit for cleaning while the first remains operational.

Finally, after being properly cooled and filtered, the lube oil enters the Supply Header, which distributes the clean, temperature-regulated oil to the turbine bearings. This ensures that the bearings are adequately lubricated and protected from wear and tear, maintaining the efficiency and longevity of the turbine operation.

This structured flow path underscores the importance of each component in ensuring the effective and efficient delivery of lubrication to critical machinery.
