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 plurality 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 secure the attachment to the protectable surface (60). The latching means do not form 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.

L'invention porte sur un bouclier réfractaire de protection (10) pour gazéificateur consistant en un élément réfractaire (70, 140) fixé à la surface à protéger (60) du gazéificateur et composé de plusieurs secteurs (70, 140) angulaires prédéterminés. L'élément réfractaire (70, 140) se pose soit sur une surface horizontale (60) regardant vers le bas du gazéificateur, ou sur l'une de ses parois verticales. L'invention porte également sur un moyen de verrouillage de l'élément réfractaire comportant une projection saillant de la surface à protéger (60) et s'engageant dans une alvéole appariée de l'élément réfractaire (70, 140) qui est ainsi fixé à la surface à protéger (60). Le moyen de verrouillage ne forme pas de creux dans la surface à protéger (60) qui conserve ainsi son intégrité tout en étant protégée.
