Accordingly there is provided a high temperature bulk-solid recirculator’ adaptable to high pressure fluidized bed gasification systems, comprising; at least one bubble cap distributor for fluidizing bulk-solids, the distributor receiving a coal gas/air/inert gas/steam via an inlet pipe at a pressure higher than the operating pressure of the gasification system; a dual gas chamber collecting the bulk-solids from at least one cyclone of the system; two fluidizing pipes disposed vertically in respect of the dual gas chamber for fluidizing t e bulk-solids thereby causing transmittal of the fluidized material; a pipe angularly is posed and flowably inter connecting the at least one cyclone and the fluidizing p1 e for downlink transportation of the ash particles; and an inclined pipe disposed at angle ranging from 400 to 800 with reference to the other one of the two fluidizing pip s for recycling back the ash particulates continuously to the gasification system, there by causing the recirculator to operate as a unidirectional sealing means.
