🔍 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?
