Fuel oil is transferred from storage tanks to the settling tanks to allow for __________.
β’ Purpose of settling tanks in a fuel oil system β’ What happens to water and sediment when fuel is held warm and still β’ Difference between settling, heating for atomization, and blending with steam
β’ Ask yourself: What is the main job of a settling tank compared with a service tank or the burner itself? β’ Which option describes something that requires time and gravity rather than pressure or burner operation? β’ Which process must happen before the fuel reaches the burners for combustion, to protect the system from damage and poor performance?
β’ Verify which choice involves removing contaminants (like water and sludge) from fuel before use β’ Check which options involve processes that normally occur at or near the burner, not in the settling tanks β’ Confirm that settling tanks are used with fuel kept warm and relatively still, which promotes a specific physical separation process
