What is BS EN 14790 - Water vapour in ducts about ?
BS EN 14790 specifies the standard reference method (SRM) based on a sampling system with a condensation/adsorption technique to determine the water vapour concentration in the flue gases emitted to the atmosphere from ducts and stacks.
BS EN 14790 specifies the performance characteristics to be determined and performance criteria to be fulfilled by measuring systems based on the measurement method. It applies to periodic monitoring and the calibration or control of automated measuring systems (AMS) permanently installed on a stack, for regulatory or other purposes.
BS EN 14790 is applicable in the range of water vapour content from 4% to 40% as volume concentrations and water vapour mass concentration from 29 g/m3 to 250 g/m3 as wet gas, although for a given temperature the upper limit of the method is related to the maximum pressure of water in the air or the gas.
Note 1: For saturated conditions the condensation/adsorption method is not applicable. Some guidance is given in BS EN 14790 to deal with flue gas when droplets are present.
Note 2: 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 14790 - Water vapour in ducts for ?
BS EN 14790 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 14790 - Water vapour in ducts ?
Stationary sources of air pollution, such as factories, refineries, boilers, and power plants, emit a variety of pollutants.
BS EN 14790 describes a method for determining the amount of water vapour emitted in the atmosphere by ducts and stacks and provides several performance characteristics, together with the associated performance criteria for measurement.
BS EN 14790 describes a method described in a written procedure containing the means and procedures required to sample and analyse, such as the field of application, principle or reaction, definitions, equipment, procedures, results, other requirements, and measurements.
As a whole, BS EN 14790 specifies the standard reference method (SRM) based on sampling system for sampling and measuring oxygen concentration in flue gases emitted to the atmosphere from ducts and stacks that reduce pollution caused by harmful gases.
