Question 386Steam Plants - Assistant Engineer

The correct answer is D) dissolved salts from sea contamination. Testing boiler water for chloride content will indicate the amount of dissolved salts from sea contamination. This is because chloride ions are a key indicator of saltwater intrusion or contamination in the boiler water system. High chloride levels suggest that seawater or other dissolved salts have entered the boiler, which can lead to corrosion and other operational issues. The other answer choices are incorrect because they do not directly relate to measuring chloride content. Phosphates, total alkalinity, and methyl orange are not directly indicative of dissolved salts or seawater contamination in the boiler water.
