🔍 Key Concepts

• Boiler forced draft pressure and its effect on combustion air flow • Relationship between air flow, furnace temperature, and heat transfer surfaces (superheater, economizer, stack) • How changes in firing rate/air supply show up in common boiler operating readings

💭 Think About

• When you reduce forced draft pressure, what happens to the amount of air going through the furnace and gas passages? Think about how that would affect temperatures in different parts of the boiler. • Which of the listed discrepancies is most directly tied to how hot the combustion gases are and how long they stay in contact with heat‑transfer surfaces? • Which choice is least likely to be directly influenced by a small change in air flow and firing rate at full ahead speed?

✅ Before You Answer

• Identify which readings are directly affected by combustion gas temperature and gas flow (through furnace, superheater, and up the stack). • Eliminate any options that are mainly controlled by separate systems (for example, feedwater/condensate level controls vs. combustion controls). • Ask: If I slightly reduce air and firing rate, which of these four values would I logically expect to move toward normal because gas temperatures and heat absorption are changing?
