Waste Incineration Cems Flue Gas HCl Co Continuous Emission Monitoring System

Waste Incineration Cems Flue Gas HCl Co Continuous Emission Monitoring System

1. Basic Design Principle of WT-400 Analysis System
The WT-400 Ammonia Analysis System is a high-temperature extractive monitoring system, with a laser NH₃ analyzer as the core analysis unit. All parts in contact with the sample gas are heated and insulated above 180℃ throughout the process, ensuring accurate and stable NH₃ measurement.

2. Operating Conditions and Requirements

2.1 General Conditions

• Maximum dust content: < 2000 g/Nm³

• Flue gas temperature at sampling point: ≤ 600℃

• Sampling point pressure: -15 to 15 MPa

• Tar and benzene content: < 10 g/Nm³

• Saturated water vapor present

2.2 Environmental Conditions

• The temperature control box is installed outdoors, while the instrument is indoors.

• Ambient temperature: 5–45℃

• Relative humidity (RH): 20–85%

• Atmospheric pressure: 10–106 kPa (depending on local conditions)

2.3 Utilities and Gas Supply Requirements

• Power Supply: 220V ±10%, 50Hz ±1Hz, Power: 5 kVA (free from strong electrical interference)

• System Gas Supply:

  1. Compressed air – required to purge the sampling system and prevent blockage. Must be clean, dry, oil-free, with a pressure of 4–7 kg/cm² to ensure effective purging.

  2. Standard gas – used for preprocessing, calibration, and verification of the gas analysis system. Ensure the standard gas quality meets the system requirements to guarantee measurement accuracy.

  No.	Standard Gas Compositions	Standard Gas Concentration	Standard Gas Pressure
  1	N2	≥ 99.9999%	0.5 -10 MPa
  2	NH3	80% of the measurement rage	0.5 -10 MPa

3. Features of WTKF200 Ammonia Escape Online Monitoring System:

1. Streamlined integrated sampling probe, with a large dust holding capacity and a dust filtration capacity ≤ 100 g/NM³, no clogging.

2. Dust filtration accuracy: ＜0.1 μm

3. Analysis accuracy: ±1%FS

4. Response time: T90 ≤ 30 s

5. Mean time between failures: MTBF＞3 years

6. Maintenance interval: ＞1 year

7. The high-temperature extraction sampling method is adopted to ensure no distortion in sampling and accurate analysis.

8. High-temperature and constant temperature sampling design to ensure the accuracy of NH3 concentration.

9. The system has and automatic purging device to dust and prevent blocking.

10. Output signal: 4-20 mA; control alarm signal NO/NC, 1A/220V.
