Question 612Steam Plants - Assistant Engineer70% to pass
During high-speed operation of the main turbine propulsion unit, the heat absorbed by the lubricating oil is removed by the _______________.
AI Explanation
The correct answer is B) lube oil cooler.
During high-speed operation of the main turbine propulsion unit, the heat absorbed by the lubricating oil is removed by the lube oil cooler. The lube oil cooler is responsible for dissipating the heat generated in the lubricating oil system, ensuring the oil remains at the proper operating temperature and viscosity. This is a critical function to prevent damage to the turbine bearings and other components.
The other options are incorrect because: A) the distillate cooler is used to cool the distillate fuel, C) the lube oil purifier is used to clean the lubricating oil, and D) the sump vents are used to vent the crankcase and prevent the buildup of pressure, not to cool the lubricating oil.
