🔍 Key Concepts

• Pressure control vs. high-limit control in an automatically fired auxiliary boiler • Difference between normal operating control and safety shutdown devices • What the stack relay actually monitors and controls in an oil-fired boiler system

💭 Think About

• Ask yourself: When the desired (set) steam pressure is reached in automatic operation, is the boiler supposed to shut everything down for safety, or simply stop firing until pressure drops? • Which device in the list is directly related to pressure control, and which are related more to temperature/stack conditions or safety override? • Think about the ignition sequence: Which components are only involved at start-up and trial-for-ignition, not in normal pressure cycling?

✅ Before You Answer

• Identify which option refers to a pressure-operated control rather than temperature or stack conditions. • Separate operating limit (normal cycle) from high limit (safety trip) in your mind; they do different jobs. • Verify which device would logically cycle the burner on and off around the set pressure, without completely de-energizing the entire firing system.
