What is the issue regarding the distance between the final oxygen supply cut-off valve and the burner?

Does the distance between the final oxygen supply shut-off valve and the burner affect production? Are there any relevant specifications or standards specifying how far the valve should be from the burner? What are the advantages and disadvantages of having it too far away or too close?

Additionally, should we consider blowing in nitrogen after stopping oxygen supply to prevent tempering? The oxygen lance feeding principle of top-blown converters can be referred to for guidance.
In the years prior, the oxygen control valve located after the burner was made of Inconel 625; in recent years, it has been made of Inconel 600
