Question 1 of 27070

When raising steam on a boiler, the superheater drains should __________.

🔍 Key Concepts

• Behavior of condensate in superheater elements during warm-up • Why thermal expansion and avoiding water carryover are critical when raising steam • Standard start-up procedures for boiler superheaters

💭 Think About

• What happens inside the superheater tubes if condensate is trapped while metal temperature rises rapidly? • At what stage of raising steam do you want to be sure that only dry steam, not water, is in the superheater and outlet lines? • How do operators usually confirm that steam has fully cleared a line that may contain condensate?

✅ Before You Answer

• Which choice best prevents water hammer and thermal shock in the superheater? • Which procedure ensures the superheater and outlet piping are fully drained and warmed through before being sealed? • Which option matches the idea of keeping a path open until steam flow is clearly established, then securing it?

Question 1 of 27070

When raising steam on a boiler, the superheater drains should __________.

Remain open or partially open until steam blows through the lines, and then the valves should be closed

Be opened to remove condensate, and then closed when the first burner is lit

Be closed until just before line pressure is reached, and then given a short blow period

Be closed until after the air cock is closed, and then opened until the boiler is placed on line
