The burner as claimed in claim 10, wherein the supporting structure is tube-shaped and two ends of the supporting structure project beyond the swirler. 12. The burner as claimed in claim 1, wherein the holder is essentially tube-shaped. 13. The burner as claimed in claim 1, wherein the tip has a conical part and a cylindrical part. 14. The burner as claimed in claim 1, wherein a seal is located between the holder and the tip. 15. The burner as claimed in claim 1, wherein heat shield is made of a material with a lower coefficient of thermal expansion than the holder and the tip. 16. The burner as claimed in claim 1, wherein the interior of the holder is formed by an oil duct which runs along a longitudinal axis of the holder, andwherein heat shield adjoins the oil duct and is arranged in the downstream part of the holder, projecting beyond the holder. 17. The burner as claimed in claim 1, wherein the main burner is arranged around the pilot burner. 18. A gas turbine, comprising: a burner, comprising: a main burner, comprising: a supporting structure,a heat shield, anda holder for the heat shield, anda pilot burner,wherein the holder is located at least partially inside the supporting structure and the heat shield is located at least partially inside the holder,wherein the heat shield is secured to the holder using a first force-fit and/or a frictional connection,wherein the holder is secured to the supporting structure using a second force-fit and/or a frictional connection,wherein the burner has a tip adjoining the supporting structure, the holder, and the heat shield, andwherein the heat shield contacts the tip and the holder and is secured between the tip and the holder using a third force-fit.
