What is BS EN 14789 - Stationary source emissions about ?
BS EN 14789 specifies the standard reference method (SRM) based on the paramagnetic
principle for the determination of the oxygen concentrations in flue gases emitted to the atmosphere from ducts and stacks. It includes the sampling and the gas conditioning system as well as the analyser.
BS EN 14789 specifies criteria for demonstration of equivalence of an alternative method (AM) to the SRM by application of EN 14793:2017.
BS EN 14789 has been validated during field tests on waste incineration, co-incineration and large combustion plants and a recognized test bench. It has been validated for sampling periods of 30 min in the range from 3% to 21%. Oxygen concentration values, expressed as volume concentrations, are used to allow results of emission measurements to be standardized to the oxygen reference concentration and dry gas conditions required e.g., by EU Directive 2010/75/EC on industrial emissions.
Note: The characteristics of installations, the conditions during field tests and the values of repeatability and reproducibility in the field are given in Annex A.
Who is BS EN 14789 - Stationary source emissions for ?
BS EN 14789 on stationary waste emissions is relevant to:
- Product Engineers
- Chemical Engineers
- Manufacturers and industries using furnaces and gas towers
- Researchers and scientists
Why should you use BS EN 14789 - Stationary source emissions ?
The paramagnetic method is based on the principle that oxygen molecules are strongly attracted to a magnetic field.
BS EN 14789 describes the standard reference method (SRM), based on the paramagnetism principle for sampling and determining oxygen concentration in flue gases emitted to the atmosphere from ducts and stacks.
BS EN 14789 provides fixed criteria for pre-testing, where the performance laboratory must verify that the analyser is functioning as required and that the sample gas line and conditioning unit are in good working order before conducting field measurements.
As a whole, BS EN 14789 specifies the standard reference method (SRM) based on the paramagnetism principle for sampling and measuring oxygen concentration in flue gases emitted to the atmosphere from ducts and stacks that reduce pollution caused by harmful gases.
