Abstract

A duct operatively arranged to fluidly connect a first flue of a heating wall of a coke oven battery with a second flue of the heating wall, the duct comprising a first end, second end, a distal end and a proximal end, a passageway disposed therein, the passageway extending from the first end to the second end, a pair of proximal apertures disposed within the proximal end and open to the passageway, and a pair of distal apertures disposed within the proximal end and open to the passageway, the distal apertures arranged be in fluid communication with the passageway, wherein one of the distal apertures is arranged to be in fluid communication with the first flue of the coke oven battery and the other of the distal apertures is arranged to be in fluid communication with the second flue of the coke oven battery.

Claims (20)

1 . A duct operatively arranged to fluidly connect a first flue of a heating wall of a coke oven battery with a second flue of the heating wall, the duct comprising:

a bottom section having a first end and a second end, the bottom section having an external surface and an internal surface, the bottom section having a channel disposed within the internal surface extending from the first end to the second end, the channel having an inner channel disposed therein, the inner channel having a pair of distal apertures disposed therein, one of the pair of distal apertures in fluid communication with the first flue, another of the pair of distal apertures in fluid communication with the second flue,

a top section having a first end and a second end, the top section having an external surface and an internal surface, the top section having a channel disposed within the internal surface extending from the first end to the second end, the channel having a pair of apertures disposed therein, wherein the bottom section is arranged to accept the top section thereon forming a passageway comprising the channels of the bottom section and the channel of the top section.

2 . The duct recited in claim 1 , wherein the bottom section includes at least one groove arranged proximate from the channel and arranged within the internal surface, the at least one groove extending from the first end to the second end; and, wherein the top section includes at least one protrusion arranged proximate from the channel and extending from the internal surface, the at least one protrusion extending from the first end to the second end.

3 . The duct recited in claim 2 , wherein the at least one groove of the bottom section is arranged to accept the at least one protrusion of the top section therein.

4 . The duct recited in claim 1 further comprising:

a mating projection extending from the second end of the bottom section; and, a mating recess disposed within the first end of the bottom section; and,

a mating projection extending from the second end of the top section; and, a mating recess disposed within the first end of the top section.

5 . The duct recited in claim 4 , wherein the mating projection of the top section is arranged to engage a mating recess of a top section of an adjacently arranged duct and wherein the mating projection of the bottom section is arranged to engage a mating recess of a bottom section of the adjacently arranged duct.

6 . The duct recited in claim 1 , wherein the bottom section includes at least one protrusion extending from the external surface and extending from the first end to the second end; and, the top section includes at least one groove arranged within the external surface and extending from the first end to the second end.

7 . The duct recited in claim 1 , wherein each of the pair of apertures of the top section are arranged to be substantially aligned with an inspection casting arranged on the external surface of the top section.

8 . The duct recited in claim 1 , wherein:

the bottom section comprises one or more of:

at least one groove arranged proximate the channel and arranged within the internal surface, the at least one groove extending from the first end to the second end; or,

at least one protrusion extending from the external surface and extending from the first end to the second end; and,

the top section comprises one or more of:

at least one protrusion arranged proximate the channel and extending from the internal surface, the at least one protrusion extending from the first end to the second end; or,

at least one groove arranged within the external surface and extending from the first end to the second end.

9 . The duct recited in claim 1 , further comprising a plate, the plate arranged to be removably seated within the inner channel, the plate further arranged to cover at least one of the pair of distal apertures disposed within the inner channel.

10 . A coke oven battery, having a heating wall, a first flue, and a second flue spaced apart from the first flue, comprising the duct recited in claim 1 , wherein the duct is operatively arranged to fluidly connect the first flue to the second flue.
