Abstract

The device has a fuel mixture burned in a primary burner during formation of hot gases, which are supplied to a burner (1) for a secondary successive combustion, which is formed as a flow channel. A supporting structure is formed as a carrier plate unit (10). A hole (2) and fixing structures (5) are provided for opposite fixing. A recess is provided for the hole size in the flow channel wall. The carrier plate unit does not over lap the hole in the fixed position at the outer support (8). A collar is designed diametrically at the edge of opening.
