TR-9300D Chimney Flue Gas Continuous Emissions Monitoring
System (CEMS)
Product Introduction
The
TR-9300D Chimney Emissions Continuous Monitoring System (CEMS) is designed for
real-time monitoring of gaseous pollutants, particulate matter, and key flue
gas parameters from industrial chimneys and exhaust stacks. Integrating online
analytical technologies with environmental monitoring and data processing, the
system measures SO₂, NOx, CO,
CO₂, O₂, dust concentration, temperature, pressure, humidity, and
flue gas flow rate.
Its
modular architecture supports flexible configuration, automated data
acquisition, environmental reporting, and data transmission to environmental
monitoring platforms. The TR-9300D is suitable for industrial emission
monitoring and pollution control applications. According to the supplied
product information, the system complies with China's HJ/T 76-2007 industry
standard and has obtained an Environmental Protection Product Certification
Certificate issued by the China Environmental Protection Industry Association.
Performance Features
• Multi-parameter
monitoring: Measures gaseous pollutants, particulate matter, and flue
gas operating parameters in one integrated system.
• Continuous
online analysis: Supports ongoing emissions monitoring for industrial
stacks and chimneys.
• Flexible
modular design: Allows monitoring subsystems to be configured according to
application requirements.
• Multiple
detection technologies: Supports infrared, ultraviolet,
electrochemical, magnetic-pressure, optical, laser, and differential-pressure
methods, depending on the parameter.
• Reliable
measurement performance: Designed for high measurement accuracy, stable
data acquisition, and strong interference resistance.
• Automated data
processing: The data acquisition and processing system collects
measurements and generates environmental reports.
• Multiple communication
interfaces: Supports RS-232, RS-485, and 4–20 mA outputs, depending on
the monitoring subsystem.
• Reduced
maintenance requirements: Modular construction simplifies servicing and
helps minimize system downtime.
• Industrial durability: Designed
for long-term operation in industrial emissions monitoring applications.
Working Principle
The
TR-9300D uses multiple analytical technologies to measure pollutant
concentrations and flue gas conditions.
1. Gaseous pollutant
analysis: SO₂ and NOx are measured using infrared or
ultraviolet methods. CO is measured by non-dispersive infrared (NDIR)
absorption.
2.Oxygen measurement: O₂ concentration is determined using an electrochemical
sensor or magnetic-pressure measurement technology.
3. Particulate
monitoring: Optical or laser-based technology measures dust
concentrations in the flue gas.
4. Flue gas parameter
measurement: Differential-pressure sensing measures flow velocity and
pressure, thermocouples measure temperature, and capacitance-based sensing
measures humidity.
5. Data acquisition and
transmission: The data acquisition and processing subsystem collects
measurement results, processes the data, generates reports, and transmits
information to connected environmental monitoring platforms.
Together,
these subsystems provide continuous information on industrial exhaust emissions
and operating conditions.
