SU14544A1 - Circulation pipes to form firebox walls - Google Patents

Description

The invention relates to circulation pipes for forming a furnace stitch equipped with ribbed appendages for delivering support to bricking. In the proposed pipes these appendages are given a T-shaped shape, and they partially overlap each other with their shelves to form a solid wall.

In FIG. Figure 1 shows a section of the wall of the furnace formed by the proposed circulation pipes; FIG. 2 cross section of the pipe; FIG. 3 is a perspective view of a part of the furnace formed by cTes from circulation pipes; and FIG. 4 is a side view of the pipe.

The circulation pipe 1 (Fig. 1-4) is equipped with T-shaped ribbed appendages (Fig. 2), which are partially superimposed on each other by their shelves 8 (Fig. 1) for the continuous furnace formed walls. On the inner side between the ribs 9 of the appendages is placed a brickwork 6 of refractory

material. To eliminate the ingress of air into the furnace through the walls, the outer side of the shelves 8 is provided with bricking 7, Circulation pipes 1 enter their ends into chambers 2 and 3 (Fig. 3 and 4), which are connected to the boiler using pipes 4 and 5.

Subject Patent a.

Circulation pipes to form the walls of the furnace, equipped with ribbed appendages for delivering support to bricking, characterized in that the appendage 9-8 (Fig. 2) of each of the pipes 1 is T-shaped and these appendages to form a solid wall partially overlap each other with shelves 8 (Fig. 1, 3), and the brickwork 6 made of refractory material is placed either on one side only, between the edges 9 of the appendages, or the wall 7 is also located on the outer side of the shelves 8 of these appendages.
