NATIONAL AIROIL OIL BURNERS of the steam and mechanical types now combined into DUAL STAGE BURNERS Now, at last, the inherent advantages of both systems of fuel oil atomization ore profitably yours... within the one, new NATIONAL AIROIL Dual Stage Burner. 41 years of combustion equipment design and manufacture are in back of the Dual Stage Oil Burner ., . and, it has been thoroughly tested and proved In the field for firing: Petroleum Processing Heat* ers; Rotary Kilns; H.R.T., Scotch Marine ond Water Tube Boilers; etc. Avoilable in three sizes, the NATIONAL AIROIL Dual Stage Burner fires all grades of fuel from No. 2 to No. 6, with a ready capacity of 80 to 300 g.p.h. Further, for o perfect flame pattern, we would recommend using with the Dual Stage Burner either the NATIONAL AIROIL Universal Register for forced draft or, the NATIONAL AIROIL Tandem Unit for natural or induced draft furnaces.
