Field of the Invention The present invention relates to a cooling jacket and, more particularly, to a cooling jacket for protecting a lance for blowing an oxidant into a furnace and a burner for burning fuel with the oxidant from a high-temperature atmosphere. The present invention relates to a structure of a cooling jacket provided.

いる。2. Description of the Related Art In a lance for injecting an oxidizing agent and a burner for forming a flame used in an industrial furnace, a metal is provided around the outer periphery of the lance or the burner nozzle in order to protect the nozzle of the lance or the burner from a high-temperature atmosphere in the furnace. A cooling jacket made of a metal is provided to circulate a coolant such as cooling water to forcibly cool.

るおそれがある。However, since the surface of the cooling jacket is cooled to 100 ° C. or lower by cooling water, water vapor in the furnace atmosphere may condense on the jacket surface. When NOx, Cl 2 , and SO 2 in the furnace atmosphere dissolve into the dew water, a strong acid is generated on the jacket surface, corrodes the metal forming the cooling jacket by the acid, and the cooling water in the cooling jacket leaks. There is a possibility that.

いため、高価な流量制御装置が必要となる。On the other hand, if the surface of the cooling jacket is to be kept at 100 ° C. or higher in order to prevent dew condensation, steam is generated in the water passage in the cooling jacket, and the cooling efficiency is remarkably reduced, so that the function of the cooling jacket is sufficiently exhibited. Sometimes I couldn't do it. It is also possible to use a refrigerant other than water as the refrigerant for the cooling jacket. However, for example, when a gas is used, a strict flow control must be performed, and an expensive flow control device is required.

If the cooling jacket is damaged, the damaged lance or burner is removed from the furnace, and the damaged portion is cut and machined. In addition, there is a problem that the repair has to be performed in the re-welding procedure, and the repair requires a large cost and time. In addition, if the operation of the furnace or the like is to be continued during this time, it is necessary to always have spare lances and burners.

ャケットを提供することを目的としている。Therefore, according to the present invention, when the cooling jacket is damaged, the repair can be performed separately from the main body of the lance or the burner, and the cooling jacket can be easily repaired while preventing a decrease in the operating rate of the lance or the burner. The aim is to provide a cooling jacket that can.
