Question 1 of 27070

In the prevention of moisture carryover from a marine boiler, one important consideration is to __________.

🔍 Key Concepts

• Boiler water solids and how they affect steam quality • Difference between water level control and water chemistry control in preventing moisture carryover • Purpose of chemicals like hydrazine in boiler water treatment

💭 Think About

• Which factor has the most direct effect on how much water (and dissolved/suspended solids) gets carried into the steam line? • Does raising the water level in the drum make carryover better or worse? Think about the distance between the steam outlet and the water surface. • What is hydrazine mainly used for: controlling oxygen corrosion, or directly reducing moisture carryover?

✅ Before You Answer

• Verify which option specifically addresses solids concentration in the boiler water, not just corrosion or water level. • Consider how foaming and priming are related to dissolved and suspended solids in the boiler water. • Eliminate any choices that would obviously increase foaming or raise the water surface closer to the steam outlet.
