POST-MANUFACTURING PROCESSES FOR SUBMERGED COMBUSTION BURNER |
| 摘要 |
A portion of a submerged combustion burner is disposed into a pressure vessel. The portion of the submerged combustion burner has a welded area that has a first microstructure defined by a first number of voids. The vessel is filled with an inert gas, pressurized, and heated. Pressurizing and heating operations are performed for a time and at a temperature and a pressure sufficient to produce a second microstructure in the welded area of the burner. The second microstructure is defined by a second number of voids less than the first number of voids. |

1. A method comprising:
disposing at least a portion of a submerged combustion burner into a pressure vessel, wherein the portion of the submerged combustion burner has a first microstructure defined by a first number of voids; filling the vessel containing the portion of the submerged combustion burner with an inert gas; pressurizing the vessel containing the portion of the submerged combustion burner; and heating the vessel containing the portion of the submerged combustion burner, wherein the pressurizing and heating operations are performed for a time and at a temperature and a pressure sufficient to produce a second microstructure in the burner, wherein the second microstructure is defined by a second number of voids less than the first number of voids. |
