Abstract (en)

[origin: DE102007009922A1] The method involves forming individual flames (16.1) by individual nozzles (2). A common flame (16.3) is formed by the sum of the individual flames. The individual flames are spaced with respect to a center of the common flame and are arranged away from each other, such that the common flame forms a hollow flame with an appropriate hollow space (19) downstream to a baffle plate, where the hollow flame is open into the air flow. A back pressure or a negative pressure is formed in the hollow space by a baffle plate (3). An independent claim is also included for a burner device for the formation of individual flames or a common flame.
