  • Refractory tile, in particular for a gasifier
    Patent number: 8601959
    Abstract: In a refractory tile, at least two fixing points are aligned, any two adjacent fixing points of the alignment being spaced by a constant distance A, first (44) and last (46) fixing points of the alignment being separated, in the direction of the alignment, by distances ?1 and ?2 from first (40) and second (42) edges of the tile extending proximate the first (44) and second (46) fixing points respectively. The tile is characterized in that 0<A?(?1+?2). Application to gasifiers.
