The protective refractory shield (10) for a gasifier includes a refractory attachment (70, 140) that is mechanically secured to a protectable surface (60) of the gasifier. The refractory attachment (70, 140) includes a plurali ty of attachment members (70, 140) of predetermined angular sector. The refractory attachment (70, 140) is provided to cover a downwardly facing horizontal surface (60) of the gasifier or to be positioned upon a vertical surface thereof. Latching means for the attachment include a projecting formation that projects from the protectable surface (60) that engages a complementary shaped recess in the attachment (70, 140) to mechanically secu re the attachment to the protectable surface (60). The latching means do not fo rm recesses in the protectable surface (60) nor do the refractory attachments (70, 140) form recesses in the protectable surface (60). Thus the integrity of the protectable surface (60) is maintained while it is protected.
