Division: Conversion to reference oxygen concentration - Commission Implementing Decision of 26 March 2013 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the production of cement, lime and magnesium oxide (notified under document C(2013) 1728) (Text with EEA relevance) (2013/163/EU)

The formula for calculating the emissions concentration at a reference oxygen level is shown below:

E_{R} = \frac{{21 – O}_{R}}{{21 – O}_{M}} {* E}_{M}

Where:

E_R (mg/Nm³)

emissions concentration related to the reference oxygen level O_R

O_R (vol %)

reference oxygen level

E_M (mg/Nm³)

emissions concentration related to the measured oxygen level O_M

O_M (vol %)

measured oxygen level
