TR-9300 CEMS Flue Gas Emission Continuous Monitoring System

I. Product Overview

   The flue gas continuous online monitoring system utilizes extraction condensation sampling, backscattering dust concentration measurement, Pitot tube flue gas velocity measurement, and computer network communication technology to achieve online continuous monitoring of pollutant emission concentration and total emission from fixed pollution sources. It has been technically improved to address domestic conditions such as complex coal types, significant coal quality variations, high pollutant emission concentrations, and high flue gas humidity. Designed and finalized according to national standards, it provides a professional Chinese operating platform and Chinese reporting functions, multiple sets of analog and digital input/output interfaces, enabling fieldbus connections and the selection of various communication methods, making the system convenient and flexible to operate.

       Flue Gas Continuous Online Monitoring System (CEMS) is a fully functional, top-level online monitoring system for fixed pollution sources. It mainly consists of the following subsystems:

    1. Solid particulate matter continuous monitoring subsystem, using laser backscattering single-point monitoring.

    2. Gaseous pollutant continuous monitoring subsystem multi-component gas analyzer (SO₂, NO_X, CO, CO2, HCL, HF, NH3)

    3. Flue gas parameters continuous monitoring subsystem, including oxygen content, flow rate, pressure, temperature, humidity, etc.

    4. Data processing and remote communication system

II. Technical Description

◢ Extraction condensation method CEMS can measure SO2, NOx, O2, temperature, pressure, flow rate, dust, humidity;

◢ SO2 and NOx are measured using ultraviolet differential absorption spectroscopy (DOAS) analysis technology or infrared NDIR analysis technology;

◢ O2 is measured using an electrochemical oxygen cell;

◢ Humidity is measured using the high-temperature capacitance method;

◢ Temperature, pressure, and flow rate are measured using thermistor (PT100), pressure sensor, and Pitot tube micro-differential pressure method, respectively;

◢ Dust is measured using the laser backscattering method;

◢ Ultraviolet differential absorption spectroscopy (DOAS) analysis technology can analyze gases such as NH3, Cl2, H2S, O3, in addition to SO2 and NOx;

◢ Compared with the extraction hot and wet method CEMS, this system has the advantages of simple structure, high reliability, fast response speed, and convenient maintenance;

◢ Compared with the in-situ method, the analyzer has the advantages of supporting online calibration, small measurement value fluctuations, high reliability, and simple equipment maintenance;

◢ The analyzer has a compact structure, making it easy to transport and install.

◢ System operating data collection rate ≥90%, the detection data provided by the system has an availability rate ≥90%, and has the function of reviewing historical data.

◢ Output units: For the various parameters of the detected flue gas, the system displays them on the local analyzer panel and outputs them as 4～20mA standard analog signals. The concentration unit of gaseous pollutants is mg/Nm³, the flow rate signal measured by the flow meter should be converted to volume flow rate Nm³/s for output, and the temperature unit is ℃.

◢ The system can truly achieve unattended operation, with self-diagnostic functions and alarm functions for major component failures, including: measurement element/detection probe failure, out-of-range, insufficient sampling flow, low backflush pressure, low sampling head temperature, low sampling line temperature, pretreatment system failure, analyzer failure, etc.

IV. Product Features

   Convenient maintenance, simple operation;

   The gas cell has a micro-trace heating function, reducing the lens cleaning cycle;

   Simple system structure, high integration;

   Under the action of the extraction pump, flue gas passes through the probe and heated line directly into the gas cell to measure SO2 and NOx concentration, then enters the zirconia/humidity/extraction pump module and is directly discharged. The system has a simple structure, high integration, and convenient maintenance; 

   Core components and algorithms are entirely self-developed;

   Core components including light source, spectrometer, gas cell, humidity module, dust meter, etc., are all self-developed;

   DOAS algorithm is self-developed, giving the system strong market competitiveness.
