A yellow and smoky flame is typically a sign of incomplete combustion. To adjust this, you can try increasing the air intake by opening the air shutter or adjusting the air-to-fuel ratio to achieve a bluer and more efficient flame. If the issue persists, it may require cleaning or maintenance of the burner components.

A luminous yellow flame on a Bunsen burner indicates incomplete combustion, which can produce soot or smoke.
