Claim Text:
1. A burner for burning a fuel in a gaseous oxidizer 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 front disk affixed to the burner discharge end of the tube, the front 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, the fuel nozzle including a fuel pipe defining an interior space and terminating in an end portion, the fuel pipe defining a plurality of orifices adjacent the end portion and passing therethrough, a corresponding plurality of hollow tubes extending radially outwardly therefrom, each of the plurality of hollow tubes in fluid communication with the interior space defined by the fuel pipe and configured to deliver fuel from the interior space defined by the fuel pipe into the tube; and (e) a slotted member, having an interrupted outer surface having an outer dimension and a length, disposed within a portion of the tube and affixed to the front disk, the slotted member defining an interior void therein that opens to the hole defined by the front disk, the outer dimension being less than the inner dimension of the tube thereby defining an passage therebetween, a plurality of elongated slots defined through the outer surface of the slotted member along 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.
