Refractory system for lining the interior walls of high-temperature furnaces or boilers and method of protection

A refractory tile system comprising:

• a base tile having a front face and a back face, wherein the back face of the base tile comprises at least one recess for mounting the base tile to a wall using an anchoring system, the back face of the base tile further comprising an evacuation channel in communication with the at least one recess;
• and
• a shielding tile having a front face, a back face, a first side, and a second side opposite the first side;
• wherein the first side of the shielding tile includes a protrusion extending from the back face of the shielding tile, the protrusion being configured to couple to the base tile, such that the shielding tile is suspended from the base tile when the base tile is mounted to the wall;
• and
• wherein the second side of the shielding tile includes an overhang extending from the front face of the shielding tile, such that in a mounted position, the overhang covers a portion of an adjacent shielding tile, and wherein the base tile and the shielding tile are connected in a mounted position by a cooperating system, wherein sliding protrusions extending from the entire length of a third side and a fourth side opposite the third side of the shielding tile extend into sliding recesses present along the entire length of the corresponding third and fourth sides of the base tile.
