A gasification reactor (1) comprising a gasifier (2) having a tubular gastight wall (3) with a discharge channel or dip tube (15, 40, 60) at its lower end leading into a lower slag collection bath (17). The gastight wall and the slag collection bath are arranged within a pressure vessel (18, 41, 61). An annular space (20, 42, 62) between the pressure vessel and the gasifier with the discharge channel is separated in a high pressure top section (21, 44, 64) and a low pressure lower section (22, 45, 65) by a sealing arrangement (23, 43, 63) comprising a damper (25, 50, 70). The damper can for instance be a hydraulic lock (50, 70), or a lower seal (25, 66-70) at a distance below an upper seal (24, 71). |
