Monitoring emissions brings benefits
With the development of modern industry, air pollution is receiving increasing attention. Various pollutants in the air not only cause a series of economic losses, but are also closely related to human health and the entire ecological environment. The CEMS system has emerged and is widely used to monitor the concentration and total emissions of gaseous pollutants. It is an essential link in combustion and emission processes.

Using the CEMS system can:
Check the operating status of equipment (dust removal, desulfurization, denitrification, boiler combustion conditions, etc.) and return the operating parameters
• Improve equipment operational efficiency and fault diagnosis
In accordance with environmental protection requirements, it is used for monitoring emission standards and measuring emissions

Application scope
Monitoring of emission sources of pollutants generated in industrial processes, as well as control and monitoring of flue gas desulfurization and desulfurization systems:
• Thermal power plants
Industrial kilns and boilers
Civil heating boiler
• Steel metallurgy
• Garbage incineration plant
• Petrochemical industry
• Cement industry, etc

System Overview
The entire system adopts Siemens' mature analysis and control technology and sampling preprocessing technology, and is flexibly optimized according to the specific operating parameters and technical requirements on site, fully meeting the requirements of users and ensuring the best performance price ratio of the system.
Siemens fully leverages the advantages of internationally renowned companies, maintains a leading level in gas analysis technology, and provides sufficient guarantees for system reliability and quality, providing a complete set of services such as fast and effective technical consulting, design, engineering commissioning, after-sales service, spare parts supply, etc. for domestic users.
At present, Siemens' devices of this type have been widely used in various countries around the world, with a large number of successful achievements in industries such as thermal power plants, metallurgy, petrochemicals, and building materials, and have achieved good results.

Composition of Continuous Smoke Monitoring System
The Siemens continuous emission measurement system for flue gas has been widely recognized and applied worldwide, aiming to measure gaseous substances, dust, flow velocity, etc. in continuous emissions of flue gas, and achieve quantitative control of flue gas emissions.
The core of the system usually consists of the following relatively independent parts:
Continuous monitoring system for flue gas composition (before and after flue gas treatment)
Dust concentration detection system
• Smoke flow detection system
• Other additional measurement parameters
• Data collection and processing system
