Abstract:
A gas flow director comprising:an outer truncated cone comprising a generally closed larger end wall, a generally open smaller end comprising a gas outlet, and a generally solid truncated side wall;a gas inlet generally centrally located in the larger end wall of the outer truncated cone;an inner truncated cone disposed within the outer truncated cone and corresponding generally in shape to the outer truncated cone, and comprising larger end and side walls generally parallel to the larger end and side walls, respectively, of the outer truncated cone to define a space between the larger end and side walls of the outer truncated cone and the larger end and side walls of the inner truncated cone,;the inner truncated cone comprising a gas inlet in the larger end thereof aligned with the gas inlet in the larger end of the outer truncated cone, and a smaller end comprising a gas outlet aligned with the gas outlet of the outer truncated cone, defining a gas flow passage between the gas inlet and the gas outlet of the inner truncated cone,the inner truncated cone further comprising a plurality of perforations therethrough extending between the space and the gas flow passage, anda plurality of secondary gas inlets disposed in the side wall of the outer truncated cone, adjacent the end wall, or in the larger end wall adjacent the side wall or the gas inlet.
