Division Conversion to reference oxygen concentration

United Kingdom

Original text. Later amendments are not shown.

The formula for calculating the emissions concentration at a reference oxygen level (see Table 1) is shown below.

E R = 21 – O R 21 – O M × E M

Where:

ER (mg/Nm3)

  • emissions concentration corrected to the reference oxygen level OR

    • OR (vol %)

  • reference oxygen level

    • EM (mg/Nm3)

  • emissions concentration referred to the measured oxygen level OM

    • OM (vol %)

  • measured oxygen level.
