Question 621Steam Plants - Assistant Engineer

The correct answer is B) deterioration of the bowl ring gasket will cause the purifier to lose its water seal. In a disk-type lubricating oil purifier, the bowl ring gasket forms a critical water seal that prevents water from entering the purifier bowl. If this gasket deteriorates, it will allow water to mix with the oil, causing the purifier to lose its water seal. This can result in inefficient separation of contaminants and potential damage to the machinery. The other answer choices are incorrect because: A) dirt and sludge are typically discharged separately from the cooling water, C) the reclaimed oil does not lubricate the purifier's driving gears, and D) sealing water must be supplied before oil is fed to the unit for proper operation.
