Abstract

Die Erfindung betrifft ein Verfahren zur Verminderung nitroser Gase (NOx) beim Betreiben von Verbrennungsanlagen, welches dadurch gekennzeichnet ist, daß die auf einer Brennerebene angeordneten Brenner teils mit Luftüberschuß, teils mit Luftunterschuß betrieben werden, jeweils bezogen auf die vollständige Verbrennung des verwendeten Heizmittels. Schwer brennbare, stickstoffhaltige Produktionsabfälle können ebenso wie fossile Brennstoffe mit Hilfe des erfindungsgemäßen Verfahrens effizient unter Einhaltung des gesetzlichen NOx-Grenzwertes verbrannt werden.The invention relates to a method for reducing nitrous gases (NO x ) when operating combustion plants, which is characterized in that the burners arranged on a burner level are operated partly with excess air and partly with insufficient air, in each case based on the complete combustion of the heating medium used. Hardly combustible, nitrogen-containing production waste, like fossil fuels, can be burned efficiently with the aid of the method according to the invention in compliance with the legal NO x limit value.
