According to the invention, it is proposed to apply a ceramic layer to a burner for a solid or liquid fuel-fired gasification reactor on the metallic surface of a burner part facing the flame side, wherein special embodiments include applying a plurality of ceramic layers by means of the plasma spraying application technology, in particular Materials include zirconium / yttrium oxide. Advantageously, the service life of the burner is improved by the inventive coating of the burner cooling parts and thus increases the plant availability while minimizing the maintenance costs. In addition, less expensive metallic materials can be used. A higher permissible temperature of the supplied oxidizing agent makes it possible to increase the efficiency of the gasification process. |
