Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
In an industrial burner, structure forming a refractory lined combustion chamber having a restricted opening at one end, a fuel distributor member at the opposite end of said chamber, said member being provided with a cylindrical space axially aligned with and open to said chamber, said space being bounded by a cylindrical wall and an end wall, a plurality of openings extending tangentially through said cylindrical wall, means to supply combustion air to said space through said openings, an axially extending opening in said end wall, means to supply a fuel gas to said space through said axially extending opening, an oil atomizer spaced axially from and concentric with said axially extending opening, and means to supply oil to said atomizer to be discharged thereby into said space.
