PETRO'S THERMAL VISCOSITY CONTROL Model WD--AH Direct Driven, Rotary Cup Type Burner, illustration Shows Modutrol Mounted on Burner. PETRO MODEL W BURNER is avail able in two types: (1) Direct-Driven, which includes electric motor, fan, pump, rotary cup atomizer in one self-contained assembly, together with air and oil con trols. (2) Belt-Driven, containing the same assembly as above except that the integral motor is replaced by motor mounted outside burner housing and arranged for belt drive. Removable rotary cup and nozzle permit changing 8hape of flame to suit any boiler furnace requirements. Interlocking air and oil control mecha nism permits any minimum or maximum operation required within the burner's range of operation. Counter-flow Angu lar Air Vanes at nozzle increase air and oil turbulence and aid efficient combus tion of heavy fuel oils. Special oil adjustment valve meters oil to rotary cup, yet permits manual opera tion without disturbing permanent burner adjustment. A dependable and accurate control of viscosity--and hence delivered combus tion- efficiency--is through the heat applied to the oil. Petro's Thermal Vis cosity System controls this heat-applica tion at its source. Send for catalog of Petro Commercial and Industrial Oil Burners - , 1321
