Abstract

Die Erfindung betrifft ein Verfahren zur NOx-Verminde­ rung in Verbrennungsgasen durch Zuführung von Sekun­ därbrennstoff mittels eines Trägermediums in den Verbren­ nungsraum an einer Stelle zwischen Brennstoff/Luftzufuhr für die primäre Verbrennung und Sekundärluftzufuhr für den vollständigen Ausbrand, bei dem der Sekundärbrennstoff mittels eines flüssigen Trägers in den Verbrennungsraum eingebracht wird. The invention relates to a method for NO x -Verminde tion in combustion gases by supplying secondary därbrennstoff by means of a carrier medium in the combustion chamber at a point between fuel / air supply for primary combustion and secondary air supply for complete burnout, in which the secondary fuel by means of a liquid Carrier is introduced into the combustion chamber.
