Claim Text:
1. A burner for burning a fuel and an oxidizer in a gaseous stream, comprising: (a) a tube, having an inner dimension, configured to allow passage therethrough of the gaseous stream, a selected end of the tube terminating in a burner discharge end; (b) a disk affixed to the burner discharge end of the tube, the disk defining a hole therethrough; (c) an oxidizer intake configured to deliver the oxidizer into the tube; (d) a fuel nozzle configured to deliver the fuel into the tube; and (e) a slotted member, having an interrupted outer surface having an outer dimension and a length, the interrupted outer surface spaced apart from the fuel nozzle, the slotted member disposed within a portion of the tube and affixed to the disk, the slotted member terminating in a back wall, the interrupted outer surface and the back wall defining an interior void therein that opens to the hole defined by the disk, the outer dimension being less than the inner dimension of the tube thereby defining a passage therebetween, a plurality of elongated slots defined through the outer surface of the slotted member along at least a portion of the length of the slotted member, each slot directed along a different non-diametrical chord of the slotted member and fluidly coupling the interior void to the passage so that the plurality of elongated slots direct the gaseous stream from the tube into the interior void of the slotted member so as to impart both an inwardly-directed radial velocity component and a tangential velocity component to the gaseous stream, the back wall being impervious to the gaseous stream so that all of the gaseous stream must enter the void only through the plurality of slots and exit the void through the hole in the disk,
