How many different types of flame can a Bunsen burner produce?

A Bunsen burner can produce two main types of flames: the luminous flame and the non-luminous flame. The luminous flame, which is yellow and produces soot, occurs when the air supply is restricted, leading to incomplete combustion. The non-luminous flame, which is blue and hotter, occurs when the air supply is increased, allowing for complete combustion. Adjusting the air supply enables the user to switch between these flame types depending on the desired application.
