What is the function of gas analyzers in a CEMS?

Gas analyzers play a crucial role in Continuous Emissions Monitoring Systems (CEMS) by measuring the concentration of various gases in exhaust streams. The primary function of gas analyzers is to detect and quantify specific pollutants, such as carbon monoxide, sulfur dioxide, nitrogen oxides, and volatile organic compounds. This capability is essential for compliance with environmental regulations and for ensuring that emissions are kept within permissible limits.

By measuring multiple parameters or specific parameters, gas analyzers provide critical real-time data that can be used to monitor air quality and assess the performance of combustion processes. This data is then used to optimize operations, reduce emissions, and contribute to environmental protection efforts. Consequently, their role is integral to achieving effective emissions management and maintaining regulatory compliance, making the function of measuring gases the key aspect of gas analyzers in a CEMS.
