What is the MAXIMUM bearing oil discharge temperature for satisfactory turbine operation?

180 degrees F
200 degrees F
220 degrees F
250 degrees F

The correct answer is: 200 degrees F

The maximum bearing oil discharge temperature for satisfactory turbine operation is critical in ensuring the longevity and reliability of turbine components. A discharge temperature above a certain threshold can lead to degradation of the oil quality and compromise the lubrication properties necessary for the bearings. In this context, the value of 200 degrees F is identified as the maximum acceptable temperature. This temperature reflects a balance between operational efficiency and the protection of turbine components, ensuring that the bearings receive adequate lubrication without risking overheating, which can lead to premature wear or failure. Operating at or below this temperature helps to maintain optimum performance and reliability in turbine systems. This understanding underlines the importance of monitoring operational parameters and highlights why maintaining oil discharge temperatures is crucial in turbine operations.
