Flue gas measurement, also known as emission measurement, is a measurement or sampling and analysis process usually carried out on the roofs of industrial facilities or independently rising chimneys. Emission confirmation measurements must be repeated at the environmental permit stage and then routinely every 2 years.
Flue gas measurement within the scope of the Regulation on the Control of Industrial Air Pollution is carried out in the chimneys where the gases that accumulate within the enterprise, which may cause pollution, are discharged. In the Regulation, various chemical pollutants and their corresponding limit values are given in Annex-1 and Annex-5. If the pollutant with a limit value is present in the enterprise and discharged as gas through the chimney, it must be proved with the measurement report that the pollutant meets the limit value in this chimney.
