Abstract: In a combustion chamber with at least one premixing burner (110) which is fastened by means of its burner outlet (118) to a front plate (54) bounding the combustion space of the combustion chamber (60), the gaseous fuel is introduced via gas inlet flow openings (117) arranged around a burner axis (100). The fuel is mixed with the combustion air prior to ignition. The fuel concentration at the burner outlet (118) is lower at the outer edge of the flow field generated by the premixing burner (110) than it is in the inner part of the flow field. The temperature of the combustion gases at the outer edge of the bonnet-shaped reverse-flow zone (121), which gases impinge on the combustion chamber wall (63), is lower than the average temperature of the combustion gases in the bonnet-shaped reverse-flow zone (121).

Abstract: In an ozone generator, spring elements (5) of metal pointing transversely to the longitudinal direction of the tube are provided for spacing the dielectric (3) from the metallic outer electrode (1). These spring elements are either bonded directly to the dielectric (3) and are stuck onto a tape-shaped carrier which is attached to the dielectric (3) and at their free ends rest against the inside wall of the outer electrode (1). In this manner, the discharge gap is only minimally constricted and the assembly of the inner tubes (2a, 2b) is simplified.

Abstract: In ozone generators having segmented inner electrodes (7), the electric connection of the segments is effected by means of plane contact areas (10) applied to the ends of the segments. A tension rod (11) passing through all segments ensures cohesion and, at the same time, is used as the connecting element for supplying the ozone generator with power.

Abstract: In the ozone generator, the inner electrodes which have been continuous until now, are subdivided into individual electrically series-connected segments (7) which are mechanically decoupled from one another. In this manner, ozoniers of almost arbitrary length can be implemented with gap widths of around 0.5 mm.
