Verfahren und Vorrichtung zur akustischen Modulation einer von einem Hybridbrenner erzeugten Flamme

摘要

The invention relates to a method of acoustic modulation of a flame (14) produced in a hybrid burner (6) comprising a pre-mix burner (7) and a pilot burner (8) pertaining to it, by combustion of fuel supplied to the pre-mix burner (7) in a full flow and supplied to the pilot burner as a pilot flow, and by means of an acoustically modulated supply of fuel. The pilot stream is modulated, the main stream is not. The invention is particularly useful in eliminating combustion oscillations in a combustion chamber (2) to which the hybrid burner (6) is connected.
