Which of the problems listed will reduce boiler efficiency?

🔍 Key Concepts

• Combustion efficiency in boilers – how fuel, air, and mixing affect heat transfer • Effects of poor atomization or worn sprayer plates on fuel burning and soot formation • What flue gas composition (CO vs CO₂, visible smoke/clear stack) tells you about combustion quality

💭 Think About

• For each option, ask: does this condition usually mean fuel is being burned more completely or less completely? How does that affect efficiency? • Think about what a clear stack indicates compared to a smoky stack in terms of unburned fuel and soot deposits. • Consider what high carbon monoxide (CO) in flue gas means about the amount of air and completeness of combustion.

✅ Before You Answer

• For each choice, decide if it would increase unburned fuel or soot, which wastes energy and reduces heat transfer. • Recall that incomplete combustion (often indicated by CO in flue gas) means chemical energy in the fuel is not fully released as useful heat. • Verify which conditions would lead to poorer heat transfer surfaces (more fouling/soot) versus cleaner, more effective heating surfaces.
