Oxyfuel-Verbrennungsprozesse, die reines O2 anstatt Luft für die Verbrennung nutzen, sind aufgrund Ihrer höheren Verbrennungstemperaturen und fehlendem N2 ein wichtiges Mittel zur Reduktion von CO2- und NOx-Emissionen in die Atmosphäre. Zur besseren Reaktionssteuerung der Verbrennung sind allerdings Daten über die…
