A refractory insert is provided, including a main body part having a first surface defining a first sidewall, an opposed second surface defining a second sidewall, and an outer peripheral surface separating the first and second surfaces, and a mechanical mating member provided on at least a portion of the outer peripheral surface thereof. The mechanical mating member includes a retention mechanism for controlling and retaining a position of a corresponding mating member in connection therewith.

Retention mechanism for refractory inserts for reformer flue gas tunnel

A refractory block assembly for a steam reformer furnace tunnel includes a hollow main body portion having at least one through-hole having openings formed in a first side and an opposed second side of the hollow main body portion. At least one refractory insert member, having mechanical mating features on at least a portion of the outer surface thereof, resides within at least one of the at least one through-hole of the hollow main body portion.

Refractory insert members and refractory block assembly including same

A refractory block for a steam reformer furnace tunnel includes a hollow main body, at least one first mechanical mating member defining a protruded portion extending from an upper surface of the main body, at least one second corresponding mechanical mating member defining an opening corresponding to the protruded portion formed in a portion of a lower surface of the main body, at least one third mechanical mating member defining a tab provided in a portion one of a first end and an opposed second end or a first side and an opposed second side of the main body, at least one fourth mechanical mating member comprising a groove formed in the other of the first end and the second end or the first side and the opposed second side of the main body, and at least one cavity formed in the lower surface of the main body.

Reformer flue gas tunnel and refractory components therefor

A refractory block assembly for a steam reformer furnace tunnel includes a hollow main body, at least one first mechanical mating member defining a protruded portion extending from an upper surface of the main body, at least one second corresponding mechanical mating member defining an opening corresponding to the protruded portion formed in a portion of a lower surface of the main body, and at least one through-hole having openings formed in a first side and an opposed second side of the main body portion. A refractory insert member having mechanical mating features on at least a portion of the outer surface thereof resides within the at least one though-hole of the refractory block.

Refractory insert members, refractory block assembly including same and reformer flue gas tunnel assembly including same

A ceramic ferrule assembly is provided, including a head including at least one tab protruding outwardly from an inner peripheral surface thereof, and a stem having an annular flange about an outer peripheral surface thereof and having at least one slot formed therein, the slot being adapted to receive the tab and retain the tab in a stationary position when the stem is rotated relative the head, whereby the at least one tab and the at least one slot mechanically engage one another to secure the ferrule stem and ferrule head to prevent axial disassociation from one another without counter rotation.

Two-piece ceramic ferrule assembly

An array includes a plurality of refractory bricks, each having a substantially tubular body including a first end, an opposed second end, a central bore extending from the first end to the second end along the longitudinal length thereof and defining an inner surface of the refractory brick, and an outer surface extending from the first end to the second end along the longitudinal length thereof. The outer surface of each refractory brick has a shape that transitions axially between a plurality of hexagonal portions and non-hexagonal portions along the longitudinal lengths thereof, and the plurality of refractory bricks are arranged and interlocked with one another in a vertical and horizontal manner via mating members provided on the hexagonal portions of the outer surfaces thereof. A continuous plenum space is defined by the non-hexagonal portions of the refractory bricks arranged in the array.
