Improving SNCR performance

21 December 2016, Published under Cement News

In recent years the reduction of nitrogen oxide (NOx) emissions in kiln lines has been an important topic which is expected to further gain prominence as central European emission limits are set to reduce to 200mg/Nm³ at the start of 2019. NH3 slip emission will also be limited to 30mg/Nm³. To meet these new limits, current SNCR technology will need to be reconsidered as a realistic NOx reduction degree is between 50-75 per cent depending on the kiln line design.
