A heat exchanger (6) for cooling hot particulate solids, such as the separated fines from the product gas of a carbonaceous material gasification system including a tube (20) with a core (24) and vanes (28) in a cavity (26) between the core (24) and the tube (20) which form a flow path for the hot particulate, the outside of the tube (20) being in contact with a cooling fluid. …<??>This arrangement provides for effective cooling of a hot particulate in a particle stream, using gravity as the motive source of the hot particulate. |
