<p>The expansion gap protection structure for a gasifier (10) includes a solid, inflexible, non-compressible annular refractory shoulder (50) extending downwardly into an expansion gap from a metallic flange (36) that is provided at a top neck portion (14) of the gasifier(10). The annular refractory shoulder (50) extends into an annular space between a hotface layer (22) of the refractory lining (16) and the inside surface of the gasifier shell(12). The annular refractory shoulder (50) engages an annular refractory fibrous gasket means (90) on a top edge (20) of a backup layer (18) of the refractory lining (16) of the gasifier(10). An annular coil (82) of refractory rope is provided in an annular clearance space between the annular refractory shoulder (50) and the hotface layer (22) of the refractory lining (19) to plug the clearance space.</p> |
