EM-5 Continuous Emission Monitoring System (dilution method)

Overview

EM-5 has four basic parts: the dust monitoring subsystem, gaseous pollutants monitoring subsystem, flue gas parameter monitoring subsystem, system control, and data acquisition and a processing subsystem. It can monitor parameters such as SO2, NOx, O2, dust, temperature, pressure, and flow rate. Measured gas the passes filter in sampling probe for dust removal; is diluted by the probe as fixed ratio and then enters the analyzer via sampling pipeline. By adopting the ultraviolet fluorescence method (SO2) and chemiluminescent method (NOx), this analyzer can precisely measure gaseous pollutants at ppb level. The diluted gas for flue sample gas should be high dehumidification and dedusting. After flue sample gas being diluted as a fixed ratio, the dew point of the sample gas is around -30℃. Thus, no heat tracing is needed for the whole sampling pipeline. It effectively solves the technical problem that the measurement result of SO2 is on the low side for the condensation method. Also, it avoids the high operation cost and hidden danger of the heat tracing of the hot wet method.

Feature Of EM-5 Continuous Emission Monitoring System (dilution method)


  • The whole process calibration and the end calibration can be realized;
  • No heat tracing humidity removal is needed for flue gas;
  • Teflon is used for heat tracing pipe. No heat tracing is needed for the whole process that saves cost and avoids hidden danger;
  • The dilution monitoring system is applicable for the occasions which distance between application point and cabinet over 70 m;
  • The ultraviolet fluorescence method and chemiluminescent method have an obvious advantage for the measurement of the gaseous pollutants at an ultra-low level.

Application Of EM-5 Continuous Emission Monitoring System (dilution method)


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.
