Continuous Emission Monitoring System for Flue Gas HCl Co Waste Incineration CEMS Gas Analyzers

WT Online Gas Monitoring System

1. Basic Design Principle of the WT-400 Analysis System
The WT-400 Ammonia Analysis System adopts a high-temperature extractive monitoring method, with a laser-based NH₃ analyzer as the core unit. All gas-contacting components are heated and insulated to above 180℃ throughout the sampling path, ensuring stable and accurate NH₃ measurements even under challenging process conditions.

2. Operating Conditions and Requirements

2.1 General Process Conditions

• Maximum dust concentration: < 2000 g/Nm³

• Flue gas temperature at the sampling point: ≤ 600℃

• Sampling point pressure: -15 to 15 MPa

• Tar and benzene content: < 10 g/Nm³

• Presence of saturated water vapor

2.2 Environmental Conditions

• Temperature control cabinet installed outdoors; analyzer unit installed indoors

• Ambient temperature: 5–45℃

• Relative humidity: 20–85% RH

• Atmospheric pressure: 10–106 kPa (depending on site location)

2.3 Utilities and Gas Supply

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

• Compressed Air: For purging the sampling system to prevent clogging; must be clean, dry, oil-free, with a pressure of 4–7 kg/cm² to ensure effective cleaning

• Standard Gas: For system preprocessing, calibration, and performance verification; must meet the specified purity requirements to maintain 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
