Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . Device for High Velocity Oxygen Fuel thermal spraying process for coating a component, comprising: 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 (A), wherein the powder injector block having at least four powder injectors arranged in an equal circumferential distance around the axis (A) and an exchangeable hot gas section insert inside the powder injector block configured as a cylindrical bush with at least four openings, said openings being arranged in an equal circumferential distance around the axis (A) in the cylinder, wherein the bush is fixed by the at least four powder injectors extending through said openings. 2 . Device according to claim 1 , wherein the cylindrical bush comprises: a guiding groove for a definite orientation of said bush around the axis (A) and the bush is inserted from the outside of the powder injector block. 3 . Device according to claim 1 , wherein the de-Laval section has a bell-shaped configuration. 4 . Device according to claim 3 , wherein the bell-shaped de-Laval section is combined with a cylindrical barrel. 5 . Device according to claim 3 , wherein the bell-shaped de-Laval section is combined with a conical barrel. 6 . Device according to claim 5 , wherein the bell-shaped de-Laval section is combined with a full conical configuration of the powder injector block. 7 . Device according to claim 1 , in combination with a gas turbine component, the device being arranged for coating the gas turbine component. 8 . Device according to claim 1 , in combination with metallic protective coatings of the MCrAlY type for performance of a spraying process.
