Protective refractory shield for a gasifier

摘要

The protective refractory shield for a gasifier includes a refractory attachment that is mechanically secured to a protectable surface of the gasifier. The refractory attachment includes a plurality of attachment members of predetermined angular sector. The refractory attachment is provided to cover a downwardly facing horizontal surface 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 that engages a complementary shaped recess in the attachment to mechanically secure the attachment to the protectable surface. The latching means do not form recesses in the protectable surface nor does the refractory attachments form recesses in the protectable surface. Thus the integrity of the protectable surface is maintained while it is protected.
