🔍 Key Concepts

• Boiler water chemistry and why pH is kept on the alkaline side • Normal recommended pH range for auxiliary boiler water (not neutral) • What actions change alkalinity versus remove dissolved oxygen or sludge

💭 Think About

• Think about whether a pH of 7 is acidic, neutral, or alkaline and what that means for steel boiler surfaces • Consider which treatment option would move the pH in the correct direction for typical marine boiler operation • Ask what each choice (blowdown, caustic soda, scavengers, reducing alkalinity) actually does to pH and internal corrosion risk

✅ Before You Answer

• Identify whether pH 7 is within the recommended range for auxiliary boiler water • Match each option to its primary purpose: raise alkalinity, lower alkalinity, remove oxygen, or remove solids/sludge • Confirm which corrective action directly addresses pH/alkalinity rather than an unrelated water treatment problem

Question 1 of 27070

bottom blow the boiler

treat the water with caustic soda

treat the water with chemical scavengers
