CERAMIC COATING OF GASIFICATION BURNER PARTS

摘要

According to the invention, a ceramic layer is to be applied on the metal surface of a burner part facing the flame side of a burner for a gasification reactor that is fueled with solid or liquid fuel, wherein special embodiments relate to the application of even a plurality of ceramic layers by means of the application technique of plasma spraying, particularly the materials zirconium/yttrium oxide. Advantageously, the service life of the burner is increased by the claimed coating of the burner cooling parts. Thus the availability of the system is increased while at the same time minimizing the maintenance effort. Additionally, less expensive metal materials can be used. Due to a higher permissible temperature of the supplied oxidizing agent, an increase in efficiency of the gasification process is possible.
