From which area does the Automatic Combustion Control System not take its measurements?

• A. Combustion controls
• B. Boiler furnace
• C. Air inlet
• D. Fuel line

Answer: (A)

Automatic combustion control relies on sensors that monitor conditions affecting burning—air flow at the air inlet, fuel flow or pressure in the fuel line, and furnace conditions (like flame or temperature) in the boiler furnace. The combustion controls are the controller that uses these signals to adjust valves and actuators, not a location where measurements are taken. Therefore, measurements are not taken from the combustion controls themselves.
