<p>A gasification reactor (1) and a process for the production of syngas by gasification of a carbonaceous feed. The reactor comprises a gasifier unit with a discharge channel (4) for discharging a stream of slag-loaded hot syngas and a quencher (5) for supplying a flow of quench gas into the discharge channel (4). At least one blaster (10) is arranged comprising at least one blast nozzle (12), such as a blast lance, in line with the flow direction of the quench gas. The blaster (10) can be connected to a source of pressurized gas, such as syngas, nitrogen, carbon dioxide, steam or the like. The blaster can be actuated periodically to blast away slag deposits.</p> |
