EM-5 Continuous Emission Monitoring System (In-Situ)


EM-5 continuous emission monitoring system (In-situ) is composed by dust monitoring subsystem, gaseous pollutant monitoring subsystem, flue gas parameter monitoring subsystem, system control and data collecting-processing subsystem. It can monitor parameters of SO2, NOx, O2, dust, temperature, pressure and velocity in gas. In addition, it can be extended to monitor parameters of HCI, HF, CO, CO2 and humidity according to special occasions. The measured gas passes through sampling probe for dust removal and then enters high-temperature gas analysis module (DOAS technology) for measurement and analysis. Without tracing pipe and condenser, the system has fast response time and solves the technical problem effectively that SO2 will be absorbed by the condensate water and lead to low measuring results. The system owns significant advantages in low concentration measurement occasions.

Feature Of EM-5 Continuous Emission Monitoring System (In-Situ)

Adopt UV differential optical absorption spectroscopy (DOAS) analysis technology and chemometrics algorithm, which are advanced NOx online analysis method with low detection limit of 1mg/m3; Use holographic grating for light splitting and diode array for detection to obtain complete and continuous absorption spectrum with high resolution, low detection limit, small temperature drift and fast response time; Without condensation process to prevent SO2 from absorbing by condensed water and lead to low measurement, which can reflect real working condition; Without tracing pipe; fast response time and low cost; Compared with extraction method, it owns advantages of accurate measurement, good reliability, low investment cost, fast response speed and etc.

Application Of EM-5 Continuous Emission Monitoring System (In-Situ)

Apply to exhaust emission monitoring and process control such as coal-fired power plants, garbage power plant, cement, glass, lime factory, ceramics factory, sinter, coke oven, desulfurization, denitration technology and etc.
