Abstract:
PCT No. PCT/GB97/02000 Sec. 371 Date Oct. 4, 1999 Sec. 102(e) Date Oct. 4, 1999 PCT Filed Jul. 23, 1997 PCT Pub. No. WO98/03256 PCT Pub. Date Jan. 29, 1998There is described a furnace of the kind in which a toroidal fluid flow heating zone may be established. The furnace includes a chamber (7a) in which there is provided an inner block and a ring of angled blades (21) between the inner block and an inner wall of the chamber (7a). Means (4a) is provided for delivering fluid into the chamber in such a way that the fluid passes through gaps between the blades and establishes a toroidal fluid flow heating zone in the chamber above the ring of angled blades. Means (23) is also provided for injecting feed particulate material into the chamber in a region where the toroidal fluid flow heating zone is to be established. In one arrangement, means (49) is additionally provided for injecting fuel into the chamber in a region above the ring of angled blades so that the region in the chamber at which the heating zone is established is elevated above the ring of angled blades. In another arrangement, means (33) is provided for cooling the inner block.
