Abstract

A system and method for repairing a coke oven having an oven chamber formed from ceramic bricks. A representative system includes a insulated enclosure insertable into the oven chamber and includes removable insulated panels that define an interior area for workers to work in. The insulated enclosure is movable between an expanded configuration and a compact configuration and moving the enclosure to the expanded configuration will decrease the distance between the insulated enclosure and the walls of the oven chamber. Removing the panels exposes the ceramic bricks and allows workers within the interior area to access and the bricks and repair the oven chamber while the oven chamber is still hot. A loading apparatus lifts and inserts the insulated enclosure into the oven chamber. The insulated enclosure can be coupled to additional insulated enclosures to form an elongated interior area.

First claim

We claim:

1. A structure configured to be inserted into a heated area, comprising:
a ceiling portion;
a floor portion; and
a first side portion; and
a second side portion opposite the first side portion,
wherein—
the structure is expandable from a first configuration to a second configuration,
in the first configuration, the ceiling portion is spaced apart from the floor portion by a first distance,
in the second configuration, the ceiling portion is spaced apart from the floor portion from a second distance greater than the first distance, and
the structure is configured to withstand temperatures at or above a temperature of at least 1000° F.

2. The structure of claim 1 , further comprising a plurality of removable panels that at least partially define the floor portion, the ceiling portion, the first side portion, and the second side portion.

3. The structure of claim 2 , wherein each of the panels includes an insulation portion and a backing portion coupled to the insulation portion.

4. The structure of claim 3 , wherein the insulation portion comprises a ceramic material and the backing portion comprises metal.

5. The structure of claim 1 , further comprising a cooling apparatus used to circulate cool air from outside of the structure into an interior area of the structure defined at least in part by the ceiling portion, floor portion, first side portion, and second side portion.

6. The structure of claim 1 , wherein, in both the first configuration and the second configuration, the first side portion is spaced apart from the second side portion by the same distance.

7. The structure of claim 1 wherein, in the first configuration the first side portion is spaced apart from the second side portion by a first width, and in the second configuration the first side portion is spaced apart from the second side portion by a second width different than the first width.

8. The structure of claim 1 , wherein the heated area is a coke oven including a crown, and wherein, in the first configuration the ceiling portion of the structure is configured to be spaced apart from the crown by a third distance, and in the second configuration the ceiling portion of the structure is configured to be spaced apart from the crown by a fourth distance different than the third distance.

9. A structure configured to be inserted into a heated area having a floor, sidewalls, and a ceiling, the structure comprising:
a ceiling portion;
a floor portion; and
a first side portion; and
a second side portion opposite the first side portion, wherein—
the structure is movable between a first configuration and a second configuration,
in the first configuration, the ceiling portion of the structure is spaced apart from the ceiling of the heated area by a first distance,
in the second configuration, the ceiling portion of the structure is spaced apart from the ceiling of the heated area by a second distance greater than the first distance, and
the structure is configured to withstand temperatures at or above a temperature of at least 1000° F.

10. The structure of claim 9 , further comprising a plurality of removable panels that at least partially define the floor portion, the ceiling portion, the first side portion, and the second side portion.

11. The structure of claim 10 , wherein each of the panels includes an insulation portion and a backing portion coupled to the insulation portion.

12. The structure of claim 11 , wherein the insulation portion comprises a ceramic material and the backing portion comprises metal.

13. The structure of claim 9 , further comprising a cooling apparatus used to circulate cool air from outside of the structure into an interior area of the structure defined at least in part by the ceiling portion, floor portion, first side portion, and second side portion.

14. The structure of claim 9 , wherein, in both the first configuration and the second configuration, the first side portion is spaced apart from the second side portion by the same distance.

15. The structure of claim 9 wherein, in the first configuration the first side portion is spaced apart from the second side portion by a first width, and in the second configuration the first side portion is spaced apart from the second side portion by a second width different than the first width.

16. The structure of claim 9 , wherein the heated area is a coke oven including a crown, and wherein, in the first configuration the ceiling portion of the structure is configured to be spaced apart from the crown by a third distance, and in the second configuration the ceiling portion of the structure is configured to be spaced apart from the crown by a fourth distance different than the third distance.
