Claims (2)

1. Et affaldsforbrændingsovnsystem til reduktion af NOx-emission, hvor systemet omfatter: a) en ovn (100), som omfatter en rist (110), der understøtter et brændende affaldslag (20); b) en primær luftkilde, som tilfører primær luft (10) opstrøms for risten (110); c) mindst én sekundær dyse (120), som tilfører sekundær luft (30) nedstrøms for det brændende affaldslag (20); kendetegnet ved, at d) mindst én tertiær dyse (130), som tilfører tertiær luft (40), hvor den mindst ene tertiære dyse (130) er placeret i en afstand nedstrøms for den mindst ene sekundære dyse (120); e) et kontinuerligt emissionsovervågningssystem, som er konfigureret til at overvåge emissioner inden i og fra ovnen (100); f) en styreenhed (170), som er forbundet med det kontinuerlige emissionsovervågningssystem og er til at justere tildelingen af den sekundære luft (30) og den tertiære luft; g) et selektivt ikke-katalytisk reduktions-, (SNCR), -system (140), som er placeret nedstrøms for den mindst ene tertiære luftdyse (1 30).
2. Systemet ifølge krav 1, hvor styreenheden (170) er yderligere konfigureret til at justere tildelingen af den primære luft (10) til den primære luftkilde.
