Large Combustion Plant Directive (LCPD)
- Overview
- EmiDAS and LCPD
Overview
Large Combustion Plant Directive’s (LCPD) (Directive 2001/80/EC) aim is to improve the environment by controlling emissions of sulphur dioxide (SO2), nitrogen oxides (NOx) and dust (particulate matter) from large combustion plants.
The LCPD applies to combustion plants having thermal capacity of >50 MW and examples would include fossil-fuel power stations, petroleum refineries and steelworks.
EmiDAS and LCPD
EmiDAS helps LCPD sites comply by giving the operator the ability to ensure they satisfy the requirements outlined in the LCPD including:
-
The 95% confidence interval encompasses approximately two standard deviations of the measurement either side of the mean average value. This is known as the expanded uncertainty, whereas the standard uncertainty is one standard deviation.
-
Under the LCPD the values of the 95 % confidence intervals of a single measured result shall not exceed the following percentages of the emission limit values:
- Nitrogen Oxides: 20%
- Sulphur Dioxide: 25%
- Dust : 30%
