The article presents a detailed description of ECS/StackGuide system designed by FLSmidth Automation and FLSmidth Airloq. It provides the basis for creating economically viable systems for continuous measurements of emissions (CEMS). The package ECS/StackGuide significantly facilitates the introduction of the CEMS at various enterprises and ensures the high quality of the reporting provided by these systems. ECS/StackGuide allows production operators the real-time response to the fluctuations in emissions parameters. I.e. CEMS, instead of collection of reports, will become an instrument for prompt reduction of emissions at any metallurgical or mining enterprise.
