Systems for treating a surface of a coke plant sole flue
The present technology relates to systems and methods for reducing leaks in a system for coking coal. For example, some embodiments provide systems and method for treating a cracked or leaking surface in a system for coking coal. In particular, the present technology includes systems having one or more substances configured to reduce an airflow through one or more cracks by creating an at least partially impermeable patch. The present technology further includes methods for treating surfaces having one or more cracks to reduce an airflow through the one or more cracks.
1. A system for coking coal, comprising:
at least one oven comprising a sole flue including a floor and one or more sidewalls interacting with the floor to define an interface, wherein a surface of the sole flue has one or more leaks; and
a patch covering the one or more leaks such that the patch has a perimeter peripheral to the one or more leaks and inward of the interface, wherein the patch, in operation, reduces an undesired airflow through the one or more leaks, the patch including a substance that is at least partially flexible and is configured to withstand temperatures of at least 100 degrees Celsius.
2. The system of claim 1 wherein the substance is a high temperature-resistant ceramic paper, a high temperature-resistant ceramic blanket, a high temperature-resistant ceramic spray, a flowable ceramic, a flowable polymer, a high temperature-resistant polymer, a silica material, a dust configured to coagulate, a vapor configured to coagulate, or insulated furnace brick.
3. The system of claim 1 wherein the patch comprises at least two layers, and wherein each layer comprises a high temperature-resistant ceramic paper, a high temperature-resistant ceramic blanket, a high temperature-resistant ceramic spray, a flowable ceramic, a flowable polymer, a high temperature-resistant polymer, a silica material, a dust configured to coagulate, a vapor configured to coagulate, insulated furnace brick, a flexible coating, an inflexible coating, and/or a sealant.
4. The system of claim 1 wherein the patch has a first outer layer, a second outer layers, and an inner layer between the first and second outer layer, and wherein the first outer layer and second outer layer comprise a ceramic material and the inner layer comprises silica.
5. The system of claim 1 wherein the substance is a ceramic material, the patch further comprising insulated furnace brick positioned over the ceramic material.
6. The system of claim 1 , further comprising a rigidizer configured to decrease a permeability of the substance to increase the sealant effect of the patch.
7. The system of claim 1 wherein the patch is impermeable.
8. The system of claim 1 wherein the patch is suitable for use at a temperature of 1200 degrees Celsius.
9. The system of claim 1 wherein the patch is sealed to the surface or a structure adjacent to the surface.
10. The system of claim 1 wherein the substance is a first substance, the patch further comprising a second substance positioned over the first substance such that the first substance is between the surface and the second substance, wherein the first substance and the second substance are together less permeable than the first substance by itself.
11. The system of claim 10 wherein the patch further comprises a third substance positioned over the second substance, such that the second substance is between the first substance and the third substance.
12. The system of claim 11 wherein the first substance, the second substance, and the third substance together define the patch, and wherein the patch is impermeable and semi-flexible.
13. The system of claim 11 , wherein the first substance, the second substance, and the third substance are removably adhered to each other to form the patch before being positioned over the one or more cracks.
14. The system of claim 1 , wherein the patch does not include asbestos.
15. A system for coking coal, comprising:
at least one oven including an oven floor having a first surface;
at least one sole flue having a second surface;
at least one tunnel having a third surface; and
a patch covering at least a portion of the second surface, wherein the patch:
is at least partially flexible,
is at least partially impermeable,
has a perimeter entirely within an outer perimeter of the second surface of the sole flue, and
is configured to withstand temperatures of at least 100 degrees Celsius.
16. The system of claim 15 wherein the patch includes a high temperature-resistant ceramic paper, a high temperature-resistant ceramic blanket, a high temperature-resistant ceramic spray, a flowable ceramic, a flowable polymer, a high temperature-resistant polymer, a silica material, a dust configured to coagulate, a vapor configured to coagulate, and/or insulated furnace brick.
17. The system of claim 15 wherein the patch comprises at least two layers, and wherein each layer comprises a high temperature-resistant ceramic paper, a high temperature-resistant ceramic blanket, a high temperature-resistant ceramic spray, a flowable ceramic, a flowable polymer, a high temperature-resistant polymer, a silica material, a dust configured to coagulate, a vapor configured to coagulate, insulated furnace brick, a flexible coating, an inflexible coating, and/or a sealant.
18. The system of claim 15 , wherein the patch is applied during construction of the system for coking coal.
19. The system of claim 15 , wherein the patch does not include asbestos.
20. A system for coking coal, comprising:
at least one oven comprising an oven floor, one or more sidewalls, a chamber defined at least in part by the oven floor and the one or more sidewalls, and a sole flue beneath the oven floor, wherein:
the oven floor is configured to contact coal and coke,
the sole flue is spaced apart from the oven floor, and
the sole flue has one or more leaks; and
a patch covering the one or more leaks such that the patch has a perimeter peripheral to the one or more leaks and entirely within an outer perimeter of the sole flue, wherein the patch, in operation, reduces an undesired airflow through the one or more leaks, the patch including a substance that is at least partially flexible and is configured to withstand temperatures of at least 100 degrees Celsius.
21. The system of claim 20 , wherein the sole flue comprises a floor surface and the leaks are in the floor surface.
22. The system of claim 20 , wherein the sole flue comprises a floor surface and sidewalls extending from the floor surface, and wherein the leaks are in at least one of the sidewalls.
