    摘要: The invention relates to a device (1) for High Velocity Oxygen Fuel (HVOF) thermal spraying process for coating a component, especially a gas turbine component. The device (1) comprising a liquid fuel fired combustion chamber (2), a de-Laval section (4), a powder injector block (9) with powder injectors (8) and a barrel (7) all arranged around and along an axis (A). The powder injector block (9) comprises at least four powder injectors (8) arranged in an equal circumferential distance around the axis (A) and an exchangeable hot gas section insert (10) inside the powder injector block (9) designed as a cylindrical bush with at least four openings (11) said openings (11) arranged in an equal circumferential distance around the axis (A) in the cylinder, wherein the bush (10) is fixed by the at least four powder injectors (8) extending through said openings (11).
