The Continuous Emission Monitoring System (CEMS) for flue gas emissions is suitable for monitoring the continuous exhaust emissions of various boilers, and can monitor fixed pollution sources such as boilersindustryContinuous and real-time tracking tests are conducted on the concentration (mg/m3) and emission rate (kg/h, t/d, t/a) of particulate matter and gaseous pollutants in the flue gas emitted from furnaces, incinerators, etc.
By using direct extraction method, the concentration of particulate matter, sulfur dioxide (SO2), nitrogen oxides (NOX), oxygen (O2) content, flue gas temperature, flue gas pressure, flue gas flow rate can be continuously monitored online. It can also increase carbon monoxide (CO), carbon dioxide (CO2), hydrogen chloride (HCL), hydrogen fluoride (HF), ammonia (NH3), hydrocarbons (CHX), humidity, etcparameterThe measurement.
Due to the use of direct extraction method to measure the concentration of pollutants in flue gas, the system can calibrate the analyzer online with standard gas to ensure the accuracy of monitoring data. Gas analysis uses non dispersive methodsinfraredAbsorption method; The monitoring of oxygen content adopts the British SST threaded high-temperature zirconia oxygensensor(O2 sensor) - O2S-FR-T2-18C.
O2S-FR-T2-18C/B/A is a zirconia oxygen sensor with a sensitive element of zirconia. It uses two zirconia disks with a sealed space in between. One of the functions of the tray is a reversible oxygen pump, which sequentially fills the sample gas and evacuates this small space. Another disk is used to measure the oxygen partial pressure difference ratio and obtain the corresponding sensing voltage. When the zirconia disk operates as an oxygen pump, the required temperature of 700 ° C is generated by the heating element (the matching circuit board O2I-FLE-092 can provide heating and linearity)simulationQuantity output function. ). The time it takes for an oxygen pump to reach the rated low and high pressure within a small space range corresponds to the oxygen partial pressure value in the environment.

The entire measurement range is linear. The factory default is 0-25%. When configuring the 0-100% range, customers can customize the analog output range to meet practical applications. The output can be configured as 4-20mA and 0-10VDCorRS232interface
UK SST OxygentransmitterThe sensor OXY-LC-485 circuit can provide SST series dynamic oxygen sensorspower supplyAnd control. The SST series oxygen transmitter does not directly measure oxygen concentration, but rather measures the partial pressure of oxygen in the gas. In order to directly output oxygen concentration, the oxygen transmitter IXY-LC-485 must be calibrated in air or in a gas with a known specific reference concentration. Application: Combustion control includes oil, gas, and biomass boilers; Composting; Laboratory and building air quality monitoring; Including personal safety in enclosed spaces.
