A correctly adjusted oil burner flame should exhibit which color flame body?

A correctly adjusted oil burner flame should ideally exhibit a blue flame body. The blue color indicates that the fuel is burning efficiently and completely, which is essential for optimal performance and minimal emissions.

When the flame is blue, it signifies that there is an appropriate mixture of air and fuel, leading to a clean combustion process. This not only ensures that the burner operates efficiently but also minimizes the production of carbon monoxide and soot, which can occur in improperly adjusted burners.

While orange or red flames can occur due to incomplete combustion or the presence of soot, this indicates an underlying issue that needs to be corrected for the safety and efficiency of the burner operation. Blue flames are generally the standard for assessing a well-adjusted oil burner flame.
