🔍 Key Concepts

• Pneumatic automated combustion control systems – how air pressure signals are used to position fuel/air controls • The meaning of bias in control systems – a fixed offset added to or subtracted from a signal • Difference between control, loading, and supply pressures in a pneumatic system

💭 Think About

• In a combustion control loop, which pressure actually represents the ‘command’ or ‘signal’ that tells an element (like a valve or damper) what to do? • When you apply a fixed offset (bias) to make the burner run slightly richer or leaner, which pressure are you shifting? • Does bias usually act on the source air to the whole system, on the actuator force, or on the signal that determines the setpoint or output?

✅ Before You Answer

• Be clear on the role of supply pressure (often plant air or regulated source pressure) versus signal pressures inside the controller • Identify which pressure is used as the main signal in the combustion controller that can be shifted up or down by a fixed amount • Ask: If I wanted to make the burner always fire a little higher or lower than normal, which pressure would I intentionally ‘offset’ in the system?
