Continuous Monitoring Required
Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants.
EN 14181 Standard
Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives and regulations set.
QAL2 and AST Procedures
Two major parts of this on-going quality assurance cycle are the QAL2 and AST procedures. A test laboratory performs tests on the systems on-site and determines whether the systems fulfill the set requirements or not.
What you need to know about mercury emissions monitoring
Gasmet Technologies has published a new White Paper on the monitoring of mercury emissions to air from industrial processes. This paper focuses on summarizing the changes in measurement requirements and emission limits for Large Combustion Plants (LCPs), produced by The Commission’s Joint Research Center, and adopted by European Commission. After reading this White Paper you will learn what LCP BREF means in practice and how to prepare, who it concerns, the new continuous measurement requirements, and the new emission limits.
Case: Thetford Power Station
“The system has performed very well, with very little maintenance required. Zero point calibration with nitrogen (background) just takes a few minutes each day and is fully automated. Water vapour calibration is conducted at least once per year, but under normal circumstances no other calibration is necessary.” says Operations Team Leader Richard Bloomfield
