Blue frame burnerIn the blue flame burner some of the hot gases from the flame are recirculated back to the inlet where they mix with and heat the combustion air. The fuel oil is, during normal firing, introduced into the hot recirculating gases and vaporizes. When the hot flue gases and gaseous fuel mix with the combustion air it burns with a blue flame without visible smoke. This is the closest to stoichiometric combustion one can get with a commercial burner today.
