Abstract
A system for supporting and cooling a furnace roof comprised of refractory bricks comprises a plurality of roof support members extending across the furnace and being supported from above the furnace roof. The support members are provided with internal channels for circulation of a cooling fluid, and are provided with side surfaces adapted to support rows or refractory bricks between adjacent roof support members. The system eliminates the need to suspend individual bricks from above the roof, and provides simultaneous support and cooling of the roof structure.
Claims22
A roof for substantially covering an interior space of a furnace, the furnace roof comprising:
- a plurality of elongate roof support members extending across a top of the furnace, with spaces being provided between adjacent roof support members;
- a plurality of refractory bricks provided in the spaces between adjacent roof support members, the roof support members and refractory bricks substantially completely covering the interior space, wherein the bricks are arranged in rows extending along the roof support members, with at least one row of bricks being provided between adjacent roof support members, each of the bricks having a bottom surface facing the interior of the furnace, a top surface facing away from the interior of the furnace, and a pair of opposed side surfaces extending between the top and bottom surfaces;
- and
- each of the roof support members having opposed sides extending along substantially its entire length, at least one of the sides being provided with a support surface which is in direct contact with the side surfaces of a plurality of the refractory bricks of one said row of bricks, and upon which said plurality of refractory bricks is at least partially supported, wherein the side surfaces of the bricks and the sides of the roof support members are shaped such that the bricks which are in direct contact with the support surface of the roof support member can be removed from the space between adjacent roof support members by raising the bricks from above the roof.
A support member for supporting a plurality of refractory bricks in a furnace roof, the support member being elongate and having a first end, a second end and a pair of opposed sides extending along substantially its entire length, each of the sides being provided with a support surface for supporting said refractory bricks, wherein said surface comprises shoulder forming a transition between upper and lower portions of one of the sides, such that a width of the roof support member between the upper portions of the sides is less than a width of the roof support member between the lower portions of the sides.
