Q

High temperature at the superheater outlet would be caused by __________.

🔍 Key Concepts

• superheater heat transfer between combustion gases and steam • effects of combustion quality and furnace temperature on superheated steam temperature • how excess air and air leaks change gas temperature

💭 Think About

• Think about which option would make the furnace / gas path hotter, not cooler, as the gases pass over the superheater elements. • For each choice, ask yourself: does this condition improve combustion and flame temperature, or does it dilute/cool the gases? • Consider what happens to gas temperature if the burner produces finer droplets versus poor mixing or extra cool air entering the system.

✅ Before You Answer

• For each option, decide if it would increase or decrease furnace/flue gas temperature at the superheater location. • Check which options would introduce cool air or cooling losses (those would usually lower superheater outlet temperature). • Identify which option would most likely lead to more complete, hotter combustion and therefore higher superheater outlet temperature.
