An assembly for supplying gas-conveyed solid fuel to the interior of a double wall gasification vessel includes a conduit (4) for conducting the fuel-gas mixture across the annular region (16) formed between the inner (3) and outer (2) vessel walls. A flexible coupling (11) is provided at one end of the conduit proximate the penetration of the fuel-gas stream across the vessel pressure boundary. An expansion joint (14), disposed about the conduit (4) and sealed to the inner vessel wall (3) conducts secondary gas into the inner vessel across the annular region (16) and prevents leakage of corrosive gases from the inner vessel interior.

A double-wall vessel for containing a high temperature, elevated pressure chemical reaction, comprising: a pressure-resistant outer vessel; an inner vessel for containing said reaction, the wall of the inner vessel being cooled by a flow of liquid coolant, the inner vessel wall and the outer vessel

A double-wall vessel for containing a high temperature, elevated pressure chemical reaction, comprising: a pressure-resistant outer vessel; an inner vessel for containing said reaction, the wall of the inner vessel being cooled by a flow of liquid coolant, the inner vessel wall and the outer vessel wall further defining an annular region therebetween; means for conveying a flow stream of gas-entrained solid fuel into the outer vessel through the wall thereof; a fuel conduit disposed within the outer vessel for accepting the flow stream entering the outer vessel and conducting the flow stream across the annular region into the inner vessel through an aperture in the inner vessel wall; a flexible coupling disposed at the outer end of the fuel conduit proximate the wall of the outer vessel; and a secondary air conduit, disposed around the fuel conduit, for conducting a flow stream of secondary air into the inner vessel, the secondary air conduit including an expansion joint between the inner and outer vessels.
