The burner is characterized in that the burner pipe () is made up of modules () which are fixed to another by fixing means () which will allow non-destructive assembly and disassembly of the modules. Hereby is obtained a burner in which it will be possible in a simple and non-destructive manner to disassembly the burner pipe () in modules () in direction from the free end of the burner () or the burner tip. As a result, the outermost module of the burner pipe () which constitutes the burner tip can easily be disassembled for repair or replacement and/or for repair or replacement of components incorporated in the burner tip so that maintenance and upgrading of the burner to the latest technology can be carried out in the simple and non-destructive manner.
