NOx Control Solutions

NOx emissions in cement plants are mainly made of NO emissions and very few NO2 emissions. Two kind of NOx are produced during pyroprocess operations: "thermal NOx" resulting from high temperature and air excess at the burner and "fuel NOx"coming from the nitrogen present in the fuel at the precalciner's level.

As a process expert, Fives designs the right solution for NOx control and reduction, combining primary technologies such as low-NOx burners and precalciners to limit NOx generation and secondary technologies such as selective catalytic or non catalytic reduction to reduce NOx levels.
