3.1 Overview
Set CEM CERT is a standardized and certified continuous emission monitoring system.
Set CEM CERT is suitable for use in many plants that require a permit in accordance
with EU Directive 2010/75/EU, the Industrial Emissions Directive.
The modular CEMS meets the current quality standards of EU standards EN 15267 and
EN 14181 (QAL1/2/3, AST). The number of components that need to be measured
depends on the type of plant as well as the fuel used. The measurement of gaseous
components takes place according to the cold-extractive or in-situ measuring procedure.
In the case of the cold-extractive measuring procedure, a sample flow for measurement
is continuously extracted from the exhaust gas stack and fed to the analysis cabinet. In
the case of the in-situ measuring procedure, sensors installed directly at the respective
measuring point measure continuously. The recorded measurement data are sent via a
connecting cable to the central unit in the analysis cabinet for further processing. The
analysis cabinet can be equipped with up to three analyzers and different sample
preparation components for the extractive measurements.
