A gasification reactor comprising a pressure shell, a reaction zone partly bounded by a vertically oriented tubular membrane wall, a horizontally directed burner having a burner head at which, in use, a combustion flame is discharged into said reaction zone, said burner protruding into the vertical wall part of the membrane wall via a burner muffle, said burner muffle comprising several vertically oriented, concentric and interconnected rings, wherein each successive ring has an increasing diameter relative to the preceding ring resulting in that the burner muffle has a muffle opening for the burner head at one end and a larger opening at its other—flame discharge—end, the rings comprising a conduit having an inlet end for a cooling medium and an outlet for used cooling medium and wherein the muffle opening for the burner head is located between the pressure shell and the membrane wall and wherein the burner muffle protrudes into the reaction zone.

1. A gasification reactor comprising a pressure shell, a reaction zone partly bounded by a vertically oriented tubular membrane wall, a horizontally directed burner having a burner head, said burner protruding into the vertical wall part of the membrane wall via a cone-shaped burner muffle, said burner muffle comprising several vertically oriented, concentric and interconnected rings, wherein successive rings have an increasing diameter relative to preceding neighbouring rings resulting in that the burner muffle has a muffle opening for the burner head at one end and a larger opening at its other—flame discharge—end, the rings comprising a conduit having an inlet end for a cooling medium and an outlet for used cooling medium and wherein the muffle opening for the burner head is located between the pressure shell and the membrane wall and wherein at least one ring of the burner muffle protrudes into the reaction zone. 2. A gasification reactor according to claim 1, wherein at the upper side of the part of the muffle which protrudes into the reaction zone a conduit is positioned to form a slag gutter and wherein the conduit has an inlet at one end for a cooling medium and an outlet for used cooling medium at its other end. 3. A gasification reactor according to claim 1, wherein the angle between the horizon and a direct line between the inner positioned ring at the muffle opening for the burner head and the outer positioned ring at the opening at the flame discharge end is between 20° and 70°. 4. A gasification reactor according to claim 1, wherein the angle between the horizon and the direct line between the inner positioned ring at the muffle opening for the burner head and the next ring, adjacent to the inner ring, is between 15 and 60°. 5. A gasification reactor according to claim 1, wherein the number of rings is between 6 and 10. 6. A gasification reactor according to claim 1, further comprising a sealing between the burner head and the inner ring. 7. A gasification reactor according to claim 6, wherein the sealing is a fibre woven or knitted wire mesh sealing. 8. A gasification reactor according to claim 1, wherein the rings are made from a low alloy steel with a Cr content up to 5 wt % or a high alloy steel with a Cr content above 15 wt %. 9. A gasification reactor according to claim 3, wherein the angle between the horizon and the direct line between the inner positioned ring at the muffle opening for the burner head and the next ring, adjacent to the inner ring, is between 15 and 60°.
