After steam has been raised and a boiler is being placed on the line, the superheater vent can be closed when __________.

🔍 Key Concepts

• Purpose of a superheater vent during boiler start-up • Relationship between boiler pressure and main steam line pressure when cutting a boiler on the line • Why draining and warming up steam lines is important before taking steam

💭 Think About

• Think about what happens inside the superheater if the vent is closed too early—what risk are you trying to avoid? • At what point, in terms of pressure and line-up, is it safe to stop venting steam through the superheater and allow it to operate normally? • Which option describes a condition that proves the boiler is ready to be matched with the existing steam system, not just internally warmed up?

✅ Before You Answer

• Identify which choice directly mentions the pressure relationship between the boiler and the steam line, not just temperature or drains. • Make sure the condition you choose would prevent water accumulation in the superheater and ensure dry steam to the line. • Verify that the step you select is something done right at the moment of putting the boiler on the line, not an earlier warm-up action.
