Optimizing flue gas denitrification plant performance using zirconia oxygen analyzers

The potentially harmful impact of excessive levels of nitrogen oxides (NOx) on both the environment and human health means emissions are subject to heavy regulation worldwide. As a way of removing residual nitrogen oxides in combustion flue gas, Flue Gas De-nitrification plants play an important role in helping to maintain NOx levels within acceptable limits. This animation shows how ABB’s AZ20 zirconia oxygen analyzers can help to control NOx levels by fine tuning the air to fuel ratio in the combustion process.
