🔍 Key Concepts

• Role of a dearating (DC) heater in removing dissolved gases like oxygen from feedwater • Sources and effects of dissolved oxygen in boiler systems (corrosion, pitting) • Difference between problems in steam/air systems (glands, exhausters) vs water treatment/feed system issues

💭 Think About

• Which component in the choices normally has the specific job of removing gases like oxygen from the feedwater before it enters the boiler? • Which options deal mainly with steam sealing or air removal, and which one directly affects the conditioning of the feedwater itself? • If you were trying to prevent oxygen-caused corrosion in a boiler, which piece of equipment would you check first for proper operation?

✅ Before You Answer

• Identify which choice is directly part of the feedwater treatment / dearation process • Confirm which equipment is specifically designed to remove dissolved gases (including oxygen) from water • Eliminate options that primarily relate to steam seals or vapor conditions, not to water conditioning
