PCT No. PCT/SE91/00305 Sec. 371 Date Oct. 20, 1992 Sec. 102(e) Date Oct. 20, 1992 PCT Filed Apr. 29, 1991 PCT Pub. No. WO91/17391 PCT Pub. Date Nov. 14, 1991.A method is provided for cooling of particulate material from a combustion plant, especially intended for cooling of fine-grained dust which has been separated from the flue gases from a PFBC power plant, and in which the material is transported pneumatically with the flue gas as transport means. A cooler is provided at the inlet of which there is a space for separation of the particulate material from the transport gas. The transport gas is removed via a gas cleaner. The particulate material is collected in a duct where it forms a particulate column. The duct includes cooling modules, suitably water-cooled, which cool the material on its way down through the duct. The duct comprises devices for the supply of a gas for stirring the material in the duct while the remaining flue gas is being separated from the particulate column. |
