Question 105Gas Turbine - Assistant Engineer

The correct answer is B) Main Reduction Gear. The electrostatic vent fog precipitator is a device used to remove oil mist from the main reduction gear area. The main reduction gear is responsible for transmitting power from the main propulsion engine to the ship's propeller. Due to the high-speed rotating components, oil mist can be generated in this area, which the electrostatic vent fog precipitator helps to remove. The other options are incorrect because the electrostatic vent fog precipitator is not used to remove oil mist from the LO (lubricating oil) storage tank, the synchro-self-shifting clutch, or the gas turbine engine. These areas have different oil mist control mechanisms specific to their systems and operations.
