🔍 Key Concepts

• Screen tubes are water-cooled tubes placed between the furnace and the superheater to shield parts from direct radiant heat. • Trace where the steam drum (A) connects downward toward the furnace area and see which labeled component those tubes enter. • Distinguish screen tubes from the main generating bank and from the superheater tubes by their position in the gas flow path.

💭 Think About

• Look closely at the tubes that hang directly in front of the furnace opening: which letter marks the lower header or drum those particular tubes connect to? • Follow the gas flow from the burner at I up through the furnace: where would you logically place screen tubes to protect the superheater and drum from the hottest radiant heat? • Compare the location of the superheater bank and generating bank: which labeled component is clearly separated by a ‘curtain’ of tubes between the furnace and those banks?

✅ Before You Answer

• Verify which label marks the steam drum (A) and then visually follow only the tubes that act as a ‘curtain’ between the furnace and the rear boiler bank. • Confirm that the component you choose is a lower header/drum serving those vertical screen tubes, not the superheater outlet or economizer. • Make sure the label you select is located at the lower end of the screen tube bank, in front of the furnace, rather than off to the side with the convection bank.
