Q

High temperature at the superheater outlet would NOT be caused by __________.

🔍 Key Concepts

• Steam superheater operation and what raises outlet temperature • Effects of air–fuel ratio (excess air vs poor atomization) on furnace gas temperature • How feedwater temperature affects, or does not affect, superheater outlet temperature

💭 Think About

• Which of these choices directly changes the furnace gas temperature that is actually heating the superheater tubes? • Does raising feedwater temperature happen before or after steam reaches the superheater? Trace the path: feedwater → boiler → steam drum → superheater. • Between poor atomization and too much excess air, which one is more likely to create ** hotter flame** conditions at the superheater?

✅ Before You Answer

• Be clear on the flow path: feedwater → steam → superheated steam and where each option acts in that path. • Ask: Does this condition increase, decrease, or have little effect on gas-side temperature at the superheater? • Confirm which factor mainly affects water/steam side conditions vs which affects combustion-side conditions.
