“…The results of the validation measurements show that, in the area of the steep gradients in the flame front, only minor differences occur between the results of the HFB and the pressure burner. These differences may be traced back to the influence of the used probe on the flame, as shown by Sentko et al 12. In the post‐flame zone, the results of the major combustion species deviate by less than 8 %, showing the excellent performance of the developed POX burner.…”

Combustion of hydrocarbons with pure oxygen as oxidizer is used, e.g., in hightemperature processes such as the partial oxidation (POX) of hydrocarbons to produce synthesis gas of high purity. Due to the prevailing temperatures, active cooling is required for many parts. For laboratory-scale experiments, the dimensions of key parts are too small for conventional manufacturing processes. One example is the manufacturing of a burner plate especially developed for POX processes. The complex geometries of several hundreds of burner nozzles and perpendicular cooling channels across the diameter of the burner plate cannot be manufactured in a conventional way. For this burner, the advantage of chemical etching of thin sheet material and stacking of multiple sheet layouts was used to assemble the layout of the burner. The burner plate was then diffusion-bonded, allowing the complex design to be realized. The partial oxidation of CH 4 /O 2 flames at the laboratory scale could thus be studied under industrially relevant conditions.
