Question 372Steam Plants - Assistant Engineer

The correct answer is C) control the amount of boiler water solids. Maintaining proper boiler water chemistry, including controlling the amount of dissolved solids, is critical to preventing moisture carryover from a marine boiler. Excessive boiler water solids can lead to foaming and carry-over of water droplets into the steam, which can damage downstream equipment. Properly treating the boiler water to keep dissolved solids within recommended levels is an important step in boiler operation to prevent this issue. The other answer choices are incorrect because: A) adding foaming agents is not an appropriate solution, as it can exacerbate the carryover issue; B) properly treating with hydrazine is important, but does not directly address the solids control aspect; and D) maintaining a high water level alone does not prevent moisture carryover caused by excessive dissolved solids.
