Abstract

A flue block for a heating wall of a coke oven battery, the flue block having a proximal end and a distal end, the flue block comprising a first aperture disposed within the flue block, and a riser arranged in said first aperture. The flue block may also comprise a second aperture disposed therein, the second aperture spaced apart from the first aperture, and a second riser arranged in the second aperture. The flue block may be configured such that the riser is arranged to extend past the proximal end of the flue block. The flue block may be also configured such that the first riser extends past the proximal end. The flue block may be further configured such that the second riser extends past the proximal end.

Claims (29)

1 . A flue block for a heating wall of a coke oven battery, the flue block comprising:

a block body having a top surface and a bottom surface;

a first aperture and a second aperture extending through the block body from the top surface to the bottom surface; and,

a first riser arranged in the first aperture and a second riser arranged in the second aperture, wherein:

the first riser and the second riser are integrally formed with the block body within the respective apertures; and,

a top of the first riser defines a first height and a top of the second riser defines a second height, both heights measured from the top surface of the block body, wherein at least one of the first height and the second height is greater than zero.

2 . The flue block recited in claim 1 , wherein the first height and the second height are different.

3 . The flue block recited in claim 1 , wherein both the first height and the second height are greater than zero.

4 . The flue block recited in claim 1 , wherein the block body further comprises:

a first side end having a protruding section extending therefrom; and,

a second side end having a recessed section therein, wherein the protruding section is arranged to be at least partially seated within the recessed section of an adjacently arranged flue block.

5 . The flue block recited in claim 1 , wherein the top surface comprises at least one groove extending thereacross.

6 . The flue block recited in claim 1 , wherein at least one of the first riser and the second riser comprises a countersink within the bottom surface of the block body.

7 . The flue block recited in claim 1 , wherein the second riser comprises:

a recess within its top, and wherein the recess is constant in width in a first direction and variable in width in a second direction perpendicular to the first direction.

8 . The flue block recited in claim 2 , wherein both the first height and the second height are greater than zero.

9 . The flue block recited in claim 2 wherein the block body further comprises:

a first side end having a protruding section extending therefrom; and,

a second side end having a recessed section therein, wherein the protruding section is arranged to be at least partially seated within the recessed section of an adjacently arranged flue block.

10 . The flue block recited in claim 3 , wherein the block body further comprises:

a first side end having a protruding section extending therefrom; and,

a second side end having a recessed section therein, wherein the protruding section is arranged to be at least partially seated within the recessed section of an adjacently arranged flue block.

11 . The flue block recited in claim 2 , wherein the top surface comprises at least one groove extending thereacross.

12 . The flue block recited in claim 3 , wherein the top surface comprises at least one groove extending thereacross.

13 . The flue block recited in claim 4 , wherein the top surface comprises at least one groove extending thereacross.

14 . The flue block recited in claim 2 , wherein at least one of the first riser and the second riser comprises a countersink within the bottom surface of the block body.

15 . The flue block recited in claim 3 , wherein at least one of the first riser and the second riser comprises a countersink within the bottom surface of the block body.

16 . The flue block recited in claim 4 , wherein at least one of the first riser and the second riser comprises a countersink within the bottom surface of the block body.

17 . The flue block recited in claim 5 , wherein at least one of the first riser and the second riser comprises a countersink within the bottom surface of the block body.
