A burner incorporating a pilot cone and a mounting insert is provided. The pilot cone is constructed as a pilot cone assembly which is decoupled from the mounting insert. Further, an operating method for increasing the service life of a burner which incorporates a pilot cone assembly and a mounting insert is provided. The pilot cone assembly has a cone side and incorporates at least one further side where the further side is arranged to be essentially parallel to one of the sides of the mounting insert and spaced apart from it, so that between the further side and the side of the mounting insert there is a defined gap. In an operation of the burner, the gap is significantly reduced by the thermal expansion in at least at one point of contact between the further side and the side of the mounting insert. Finally, an assembly method is provided.

Burner, operating method and assembly method

An assembly () includes a plurality of separate pie-shaped segments () forming a disk () around a central region () for retaining a plurality of tubes () in a concentrically spaced apart configuration. Each segment includes a support member () radially extending along an upstream face () of the segment and a plurality of annularly curved support arms () transversely attached to the support member and radially spaced apart from one another away from the central region for receiving respective upstream end portions of the tubes in arc-shaped spaces () between the arms. Each segment also includes a radial passageway () formed in the support member for receiving a fluid segment portion () and a plurality of annular passageways () formed in the support arms for receiving respective arm portions () of the fluid segment portion from the radial passageway and for conducting the respective arm portions into corresponding annular spaces () formed between the tubes retained by the disk.
