FIELD: transport.SUBSTANCE: conveying of powder including the dust in fluidised bed transfer channel from inlet to at least one outlet comprises powder feed into transfer channel at inlet point. Gas is fed to transfer channel to ensure powder fluidisation in said channel at said point of discharge downstream of transfer channel. This method comprises gas removal from transfer channel via gas outlets into dust separator. Said separator has inlet for gas loaded with dust, first dust outlet and second outlet for gas wherefrom dust is removed. Besides, it includes dust separation from removed gas. Note here that dust is separated from returned gas in cyclone and return of isolated dust from said separator via said first dust outlet to powder nearby said first discharge point downstream of transfer channel. Separated dust to added back to powder in mixing zone at cyclone bottom section.EFFECT: electric power savings.5 cl, 4 dwg |
