Refractory tube wall lining for an incinerator

Abstract

Refractory lining of a tube wall (2) for an incinerator, comprising at least four refractory tiles (3) of ceramic material, which are arranged next to and above one another, wherein the tiles at their rear side, which is facing the tube wall (2), are provided with a vertical insertion channel (10) for mounting the tiles upon the holders (7) of the tube wall, wherein a free space (11) is formed between the tiles (3) and the tube wall (2), which space is filled with a curable pouring compound, and wherein a spacer (20) is provided adjacent to four mutually adjoining edges (12) of the at least four refractory tiles (3). Alternative embodiments are characterized by the use of a head bolt, and / or a wedge element (50) and / or a clip-element (60).

Description

technical field [0001] The present invention relates to a refractory pipe wall lining for an incinerator comprising: [0002] At least four refractory tiles of ceramic material arranged close to each other and in two rows above each other, wherein the tiles are provided with vertical insertion channels on their pipe wall side facing the pipe wall, and four of them an edge of each of the tiles is adjacent to an edge of each of the three other tiles; [0003] A holder for each tile, wherein the tile holder is provided with anchors attached to the pipe wall, and wherein in the installed position of the liner the holder extends substantially perpendicular to the pipe wall and the holder is partly extending into the insertion channel, [0004] And wherein a free space is formed between the tile and the pipe wall. [0005] The refractory lining according to the invention is designed to be applied on the tube walls (also called membrane walls) of (waste) incinerators in order to p...

Problems solved by technology

[0012] Furthermore, proper alignment of the tiles both horizontally and vertically during the construction of known linings is very time-consuming, since a free space with a predetermined optimum value is provided between the tiles and the pipe wall while a predetermined maximum value is provided between the tiles. Optimal value of mutual seam distance (add height and seam width) is difficult

[0013] Disadvantageously, during the pouring of the concrete mortar into the free space between the tiles and the pipe wall of the known lining, there is a great risk of the joint material extruding from the joint between the tiles due to the hydrostatic pressure of the mortar

Therefore, known linings have a maximum of two rows of tiles that can be stacked and subsequently provided with concrete mortar due to the great risk of joint material expulsion at the bottom row of tiles at the same time when filling the free space behind three or more rows of tiles Shortcomings

Furthermore, due to the flow of mortar into the tile joints, the risk of tile breakage during operation is greatly increased
