ABSTRACT:
An improved burner for attaining an improved combustion of a fuel-air mixe includes a plurality of vanes extending generally longitudinally of and disposed about an axis of the flow of the air-fuel mixture, each of the vanes having a first and a second end joined by first and second longitudinal edges. The first ends being contiguously arranged to extend along the circumference of a circle coaxial with the axis, the first edges defining a cylindrical surface coaxial with the main axis, and the second edges defining a conical surface coaxial with the axis. The vanes being interconnected at their first ends. The vane structure being confined in a cylindrical structure defining at the one end an annular opening through which compressed air is introduced, with a fuel nozzle being provided at the center of the same end. The nozzle being located at the end of the vane structure where the vanes substantially meet at the center of the structure. The other end of the cylinder being closed at the annular space, and defining a central opening for the exit of the fuel and air mixture, where the combustion of the mixture takes place. The intimate mixture of the air and the fuel being the result of the intermixing of the air with the atomized fuel, the air entering through the opening of the vane structure.
