How does a Bunsen burner produce a blue flame?
If the air hole is closed there is a shortage of oxygen. Combustion is incomplete and less energy is transferred. A blue flame from a Bunsen burner transfers more energy than a yellow Bunsen flame as complete combustion gives a blue flame. Incomplete combustion gives a yellow flame and so less energy is released.
