🔍 Key Concepts

• automatic boiler safeties on fuel systems • relationship between steam pressure and boiler firing rate • what condition is dangerous if fuel continues but demand/load is low

💭 Think About

• Ask yourself: in what situation would it be unsafe to keep sending fuel to the furnace of an automatically fired boiler? • Which of these conditions would indicate that the boiler is already producing enough (or too much) steam? • Which options are more about water/feed conditions or air conditions rather than overall boiler pressure and load?

✅ Before You Answer

• Identify which choice represents an over-pressure safety condition. • Eliminate any choices that do NOT directly indicate the boiler is already making too much energy. • Confirm which condition should cause the burner to trip and fuel valves to shut in order to protect the boiler.
