🔍 Key Concepts

• the effect of excess air entering a boiler through leaks instead of burners • how air leaks influence combustion efficiency and heat transfer to the superheater • relationship between combustion quality and both temperature and fuel rate

💭 Think About

• Think about what happens to the flame and gas temperature if extra cold air is pulled into the boiler away from the burners. • How would cooler furnace gas temperatures affect the temperature at the superheater outlet? • If the boiler is getting extra, unmeasured air through leaks, what has to happen to the fuel rate to maintain the same steam output?

✅ Before You Answer

• Consider whether unwanted air leaks make the furnace gas hotter or cooler overall. • Decide how a change in furnace gas temperature would influence superheater outlet temperature (higher, lower, or variable). • Determine if reduced combustion efficiency from air leaks would increase or decrease fuel consumption for the same steaming rate.
