The tiles are provided with continuous open grooves into which the tile holders engage. In the tube wall are provided inlet openings via which air can be introduced into the gap between the tube wall and the protective cladding. Also provided are outlet openings through which air can be removed from the wall. The air supply openings are arranged in the region of the open grooves of the tiles, with the result that the supplied air flows directly into the grooves and is distributed through these grooves over the entire wall.

Abstract: A fireproof wall intended, in particular, for use in a combustion furnace has a tube wall of tubes connected by webs and a fireproof and fire-tight protective lining which is arranged upstream of the tube wall at a distance therefrom and has a plurality of fireproof plates (tiles) which are arranged alongside and above each other and are fastened to the webs of the tube wall via in each case at least one plate mounting. An intermediate space is present between the tube wall and the protective lining and, at least in certain zones, contains a particulate filler material which increases the transfer of heat between the protective lining and the tube wall. Material selection and the zonal local distribution of the particulate filler material make it possible to deliberately influence the transfer of heat both quantitatively and locally and therefore to optimally adapt it to the respective operating requirements of the combustion furnace.

Abstract: A method is proposed for producing three-dimensional structures, especially microlenses, in a substrate using an etching process, at least one original shape having a known original surface shape being present initially on the substrate in a plurality of places. The etching process has at least one first etching removal rate a1 and a second etching removal rate a2 which are material-dependent, and of which at least one is changeable as a function of time. The original shape is converted to a target shape by the etching process, the original surface shape of the original shape and the target surface shape of the target shape to be reached being known before the beginning of the etching process. In order to achieve the target surface shape, at least one of the etching rates a2 or a1 is set by a change of at least one etching parameter calculated before the beginning of the etching process as a function of the etching time.

Abstract: A refractory tube wall lining comprises a multiplicity of refractory tiles (1) which are arranged next to and above one another and each have two T-shaped slots (16) which extend over the entire height of the tile. The tiles (1) are held on the lined tube wall (2) by means of in each case two screw-like tile holders (11). Brackets which are independent of the tile holders (11) are used to support the tiles (1). Stepped top and bottom edges of the tiles (1) allow the tiles (1) to move vertically with respect to one another without the seal of the tube wall lining being lost. For the same purpose, the two side edges (14, 15) of each tile (1) are fitted with a tongue (141) or a groove (151).
