Abstract
Abstract A burner system includes a plurality of evenly pressurized tanks feeding fuel oils to a radial inlet of a tubular housing which has an axial inlet on one end for pressurized air. An ejecting mouthpiece on the other end of the tubular housing has a truncated cavity for causing a thin film of fuel to flow on the converging surface of the truncated cavity to an outlet where the fuel is atomized by tearing off thin films of fuel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
176 words
A burner system comprising a tubular housing forming a mixing chamber, air supply conduit means having one end connected to one end of the tubular housing and opening axially into the mixing chamber, a pressurized air supply connected to the other end of the air supply conduit means, fuel supply conduit means having one end connected to a peripheral portion of the tubular housing and opening radially into the mixing chamber, ejector means mounted on the other end of the tubular housing and having a truncated internal cavity converging to an opening for forming a film of fuel around the truncated internal cavity to be atomized at the opening, first and second fuel tanks connected to the fuel supply conduit means, said first and second fuel tanks containing a light oil fuel and a heavy oil fuel respectively, first and second valve means Connected between the fuel supply conduit means and the respective first and second fuel tanks, and constant pressure means for supplying the same pressure to each of the first and second fuel tanks.
