The interior of the furnace shouldbe so fitted with firebrick that the atomized oil is completelyconsumed, and the flame so directed that the heat generatedis applied most efficiently to the heating surface of theIjoiler. It is necessary, further, that the air supply and its 692 November, 1920 RAILWAY .MECHANICAL ENGINEER 693 control be so arranged that only the requisite amount ofair necessary to complete the combustion is admitted atsuch points that complete combustion is at once formed. Description of Apparatus The Scarab l)urner does not differ in principle or modeof operation from the type of oil burner ordinarily used inlocomotive ser\ice in this country. The fuel oil is led bymeans of a pipe under control of a needle valve to the upperside of what may be termed an open-ended tray. The oilfalls on to this tray and immediately spreads over the
