Diffusers

Diffusers, sometimes commonly called "spinners", are a component of the burner, near the root of the flame, which create the turbulence required to achieve proper air/fuel mixing for complete combustion. In most cases, oil burners and oil/gas combination burners use one style of diffuser, while gas only burners use a different type of diffuser. Only OEM Boiler Parts has the original Kewanee engineering and sales order records to be able to determine exactly which diffuser was used on your burner as-shipped from the Kewanee factory.
