摘要： The invention relates to a device for High Velocity Oxygen Fuel thermal spraying process for coating a component, especially a gas turbine component. The device includes a liquid fuel fired combustion chamber, a de-Laval section, a powder injector block with powder injectors and a barrel all arranged around and along an axis. The powder injector block includes at least four powder injectors arranged in an equal circumferential distance around the axis and an exchangeable hot gas section insert inside the powder injector block designed as a cylindrical bush with at least four openings, the openings being arranged in an equal circumferential distance around the axis in the cylinder, wherein the bush is fixed by the at least four powder injectors extending through said openings.
