Q

When preparing to cut a boiler in on the line, you determine that the steam pressure of the incoming boiler is about 5 psig above line pressure. Which of the following steps should you take next?

🔍 Key Concepts

• Boiler cut-in procedures and the importance of matching boiler pressure to steam line pressure • Why a small pressure differential (such as 5 psig) matters when opening valves to a live steam line • Safety devices associated with boilers, such as safety valves and hand relieving gear

💭 Think About

• Think about what condition must be verified to ensure the boiler can safely join the line without causing a sudden surge or backflow of steam. • Ask yourself which option directly checks or protects against overpressure when the boiler is brought on the line. • Consider whether you should change combustion conditions (more burners), change line configuration (open a valve), or verify a safety mechanism before making the final connection.

✅ Before You Answer

• Verify which action is required by standard boiler operating procedures before opening the boiler to a live steam line. • Check which option specifically addresses pressure relief or safety rather than changing firing rate or opening to the line. • Confirm that the step you pick would be done immediately prior to placing the boiler on the line, not earlier start-up steps.
