SPEP series ultra low emission monitoring system

    SPEP series ultra-low emission monitoring system is a product specially developed for the ultra-low emission characteristics of coal-fired power plants by Nanhuan science and technology, which adheres to technology and integrated innovation, constantly summarizes experience, and effectively solves the prominent problems such as system sampling loss, poor stability, large minimum detection concentration, water vapor interference and so on.




System composition and principle

    The system consists of gaseous pollutant monitoring, particulate matter monitoring, flue gas parameter monitoring, data processing and other subsystems. Both gaseous pollutants and particulate matter are monitored by the method of direct extraction at high temperature before analysis. Among them, the gaseous pollutants are absorbed by ultraviolet spectrum, and the particles are scattered by laser.


Performance characteristics

Low detection limit and high sensitivity

Small zero and span drift and high stability

Eliminate the interference of water vapor, CO2 and other gases, with high measurement accuracy

The whole process is extracted at high temperature to reduce sample loss

Condensation upgrading to reduce SO2 dissolution loss

The detector is calibrated online to ensure stability and reliability

Dual range switching, automatic zero / range check

technical parameter


notes

1、The premise of the above performance indicators is that the ambient temperature, atmospheric pressure and flow are stable;

2、Other ranges of SO2, NOx and particulate matter can be customized;

3、Other monitoring factors and equipment can be selected, such as CO, CO2, temperature, pressure, flow rate and humidity.


Comparison between ultra low emission monitoring system and conventional CEMS

engineering application

   At present, more than 450 sets of SPEP series continuous on-line flue gas emission monitoring systems have operated stably in nearly 200 units.
