A burner supply tube, and a burner arrangement having such a burner supply tube, which includes a tube wall extending having a tube diameter and at least one integrated fuel channel extending from a fuel input at an upstream tube end to a fuel output at a downstream tube end. To enable an integrated design, the fuel channel is along the majority of the tube length helical with a gradient of at least 0.5 times and at most 5 times the tube diameter.

Burner supply tube with fuel channel

A turbomachine component having a solid body with an elongated clearance, a channel located within the clearance of that body, where the channel is free of struts between the channel and a section of the body which is surrounding the channel to provide a continuous thermal insulation gap between the channel and the section of the body. The channel and the body are built in an additive manufacturing generation process synchronously layer by layer, from a metallic powder, wherein successive layers are selectively fused to build the body and the channel. The channel is arranged inside the body as a loose component, loose inside of the clearance and distant to the body. Spacer elements are provided, wherein each of the spacer elements is physically attached to only one of its ends either to the channel or to the body and put the channel in position and distant to the body.
