Refractory anchoring devices include a main body and a mounting feature for mounting to a thermal vessel. The main body includes four anchor branch segments angled with respect to each other to form an X shape with four unenclosed cell openings, including two opposite triangular side openings and two opposite triangular end openings. In some embodiments, the main body further includes extension segments extending from and angled relative to respective branch segments to define two of the opposite openings as semi-hexagonal. Some embodiments include reinforcement segments extending from branch segments into openings, voids extending through branch segments, two anchor strips inter-engaged to form the four branch segments, and/or a single stud-welding stud for the mounting feature. Refractory anchoring systems and methods include an array of the refractory anchoring devices arranged and mounted so that the unenclosed openings of adjacent anchoring devices cooperatively form substantially hexagonal and rhombus shaped cells.

Vertical furnace reactor assembly, comprising: a reactor housing defining a processing chamber configured for processing substrates therein, the processing chamber having an opening for moving substrates into and out of the processing chamber along a main loading axis, the opening being surrounded by a stack of annular flange units including at least two of a housing flange, a gas divided ring unit, a liner suspension ring unit, a scavenger ring unit and a clamp ring unit, wherein at least two of the annular flange units are provided with mutually cooperating centering structures for centering the respective at least two flange units with respect to each other, wherein the mutually cooperating centering structures comprise a plurality of slots and a corresponding plurality of pins, wherein the slots each extend along a respective main slot axis, wherein the slot axes are directed to mutually intersect centrally with respect to the stack.

The invention relates to a process for the positioning of a corrosion-resistant coating on an internal or external metal wall (20) of a fluid catalytic cracking unit chamber, comprising: (i) the shaping of a metal anchoring structure (10) formed from a plurality of strips (12) assembled in pairs by joining assembly portions (121, 122) so as to form a plurality of cells (14), the anchoring structure comprising a plurality of fastening tabs (16) integral with strip portions other than assembly portions, (ii) the fastening of said anchoring structure (10) by welding the free edge (18) of a part at least of the fastening tabs to the metal wall (20), defining a space between a longitudinal edge (12b) of an anchoring structure and the metal wall, (iii) the insertion of a composite material into the cells (14) from the metal wall (20) and at least up to the upper longitudinal edge (12a) of each strip.

The invention relates to a wall system for a furnace, a furnace comprising such a wall system and a method for providing such a wall system.

Refractory anchoring devices include a main body and a mounting feature for mounting to a thermal vessel. The main body has the shape of two end-to-end Y's forming a central segment, two branch segments extending from each end of the central segment, and an extension segment extending from each of the four branch segments, to collectively form four unenclosed cell openings that are each semi-hexagonal in shape. Some embodiments include four reinforcement segments with each one extending into a respective cell opening, four voids with each one extending through respective adjacent branch and extension segments, an underbody gap formed under the central segment for refractory interlinking between cell openings, and/or a single stud-welding stud for the mounting feature. Refractory anchoring systems and methods include an array of the refractory anchoring devices arranged and mounted so that the unenclosed semi-hexagonal cell openings of adjacent anchoring devices cooperatively form substantially hexagonal cells.

Mounting hardware for mounting an insulation module on a furnace wall. The hardware comprises a mounting bracket embedded within the module. The bracket has a plurality of flexible tabs, each tab having a fixed end and a free end. The free ends of the tabs are arranged about a central point and are movable (flexible) relative to the fixed ends. A mounting stud is provided having a fixed end attachable to an inner surface of a furnace wall and a free end. The stud extends from the inner surface, and the stud has an annular groove adjacent the fixed end. The stud is dimensioned to extend through the mounting bracket between the free ends of the tabs and to cause the tabs to flex as the bracket moves along the stud from the free end towards the fixed end, wherein the tabs snap and lock into the annular groove when the bracket reaches the annular groove.
