🔍 Key Concepts

• Fuel/air ratio and what happens when there is too little air for the amount of fuel • How combustion efficiency is affected by poor mixing or incorrect fuel/air ratio • Typical safety responses in automatically fired boilers when combustion conditions are outside safe limits

💭 Think About

• Think about what visible signs you might see from the stack when combustion does not have enough air. • Consider what an automatic combustion control system is designed to prevent when it detects unsafe conditions. • Ask yourself: if poor fuel/air ratio affects efficiency and smoke, would a properly designed automatic system allow that condition to continue indefinitely?

✅ Before You Answer

• Verify what incomplete combustion looks like (smoke, color, unburned fuel). • Confirm how automatic safety shutdowns work in auxiliary boilers when combustion becomes unsafe (e.g., flame failure, low air, high fuel). • Check whether more than one of the listed effects can occur at the same time from an insufficient fuel/air ratio.
