Continuous Emission Monitoring System
CEMS (Continuous Emission Monitoring System) is the core of an analysis instrument. It uses automatic control technology, computer technology and special software to form one integrated system from sampling, pretreatment, gas analysis to data acquisition and transmission, so as to achieve automatic online gas monitoring which can also be applied to the monitoring of desulfurization efficiency and denitrification efficiency.
Feature
As environmental protection is a fundamental task of China which is crucial for descendants, CEMS is continuous automatic monitoring system for stationary-sources flue gas emissions pollutant concentration providing timely and accurate monitoring data for local environmental protection departments.
Continuous Emission Monitoring System (complete extracting type).
In the detection process, this method removes water, so the measurement results come from the dry flue gas, which conforms to the environmental protection laws and regulations in China.
• The method is not subject to the restrictions of flue gas temperature.
• With the constant analysis instrument for detection, it provides reliable accuracy.
• The control system can be placed at a place of easy operation and maintenance.
• Without dilution probe and dilution gas, it is characterized by small maintenance workload and low maintenance cost.
Advanced technology
Most products of CEMS are developed by China, which can reduce the cost and increase the maintenance convenience. The maintenance cycle is long and the operation and repairment is more convenient.
Application fields
Electric power, metallurgy, petrochemical, cement, waste incineration
