🔍 Key Concepts

• Location and purpose of a diaphragm type air flow transmitter in a boiler system • Difference between forced draft fan discharge, windbox pressure, and furnace pressure • Where combustion control systems typically sense air flow or air pressure for fuel-air ratio control

💭 Think About

• Think about which boiler component contains pressurized combustion air before it enters the burners, not after combustion has taken place • Ask yourself where you would want to measure stable, relatively clean air pressure/flow so the signal accurately represents the air going to the burners • Eliminate any locations that primarily contain hot flue gas instead of incoming combustion air

✅ Before You Answer

• Identify which two choices are on the air supply side and which are on the gas/flue side of the boiler • Confirm which component directly feeds air into the burner registers or ports • Verify that a diaphragm type air flow transmitter normally senses positive pressure combustion air, not negative draft or flue gas pressure
