1. A gasification reactor comprising:
a vessel having a wall and provided at its upper end with a downwardly directed burner, and provided with supply conduits for an oxidizer gas, a carbonaceous feed and a moderator gas, a combustion chamber having a wall and located in the upper half of the vessel, provided with a product gas outlet at its bottom end and an opening for the outlet of the burner at its top end, wherein between the wall of the combustion chamber and the wall of the vessel an annular space is provided, and wherein the wall of the combustion chamber comprises an arrangement of interconnected parallel arranged tubes resulting in a substantially gas-tight wall, having an inner side and an outer side, running from a common lower arranged distributor to a higher arranged common header, said distributor provided with a cooling water supply conduit and said header provided with a steam discharge conduit and wherein the steam discharge conduit and the water supply conduit are fluidly connected, at a higher elevation from the base, to a steam drum, the steam drum being located at a higher elevation than the common header, and wherein the steam drum is provided with a supply conduit for fresh water; wherein the tubes comprise a coating comprising a refractory material, the tubes being interconnected by connecting parts such that they form a gas-tight combustion chamber within the refractory wall; wherein the product gas outlet at the bottom end of the combustion chamber is fluidly connected to a dip-tube, which is partly submerged in a water bath located at the lower end of the reactor vessel; and wherein the upper part of the dip tube is provided with vertical arranged tubes or a spirally wound tube through which, in use, cooling water or steam may flow. |
