Question 164Steam Plants - 1st Asst/Chief

The correct answer is D) Oil. Boilers on ships often accumulate various types of deposits, including sludge, high temperature oxide, and corrosion deposits. However, oil deposits are the type of waterside deposit that can normally be removed by chemically boiling out the boiler. This is because oil deposits are organic in nature and can be effectively dissolved and flushed out using chemical cleaning agents during the boil-out process. The other options, such as sludge, high temperature oxide, and corrosion deposits, are typically more difficult to remove through chemical boil-out alone and may require additional mechanical cleaning or more specialized treatment methods.
