1. A burner adapted to be used in a streaming engine, comprising:
a combustion channel and a burner tip,
wherein the burner tip comprises at least one longitudinal cooling fin,
wherein the at least one longitudinal cooling fin helically circles the combustion channel along a longitudinal direction,
wherein the burner is adapted to provide a flow direction through the combustion channel,
wherein an angle between the at least one cooling fin and a plane perpendicular to the flow direction is at most 50°,
wherein the angle between the at least one cooling fin and the plane perpendicular to the flow direction is at least 6°,
wherein the burner tip comprises a heat shield providing the at least one cooling fin, wherein the heat shield is detachably connected or inseparably connected to a remainder of the burner, and
wherein the heat shield comprises a central opening and a plurality of openings that are disposed in an annular array around the central opening and that pass from a radially inner side of the heat shield to a radially outer side of the heat shield.
