KGD-MQ-525Online Gas Analysis System Product Introduction The KGD - MQ - 525 Online Gas Analysis System is designed for
specific working conditions where the sample gas contains dust,
moisture, and tar. It consists of three parts: the pretreatment
unit, the control unit, and the gas analysis unit. Based on the non
- dispersive infrared (NDIR) gas analysis technology with
independent intellectual property rights, the system can
continuously and simultaneously measure the volume concentrations
and calorific values of gases such as CO, CO2, CH4, H2, O2, C2H2,
C2H4, and CnHm in real - time. It is applied to the online gas
monitoring of process points such as coke oven gas, high - coke
gas, biomass gas, and gas holders, which helps improve gas
utilization efficiency, save energy, reduce consumption, and ensure
the safety of industrial sites. Product Features - Pretreatment Unit: Long service life and stable performance.
Straight - tube or steam sampling probes can be selected according
to different tar contents to effectively remove tar from the sample
gas. A single - stage refrigerator is configured to remove moisture
from the sample gas, and multi - stage filtration ensures the long
- term online operation of the instrument.
- Control Unit: Fully automated detection with simple operation. It
is controlled by a PLC program, which can automatically complete
gas washing and sampling, and also has a fault self - inspection
function.
- Gas Analysis Unit: Simultaneously measures gas volume concentration
and calorific value. The Gasboard - 3100 (online type) gas analyzer
with independent intellectual property rights is used for online
gas analysis and detection. It can simultaneously measure the
volume concentrations of multi - component gases such as CO, CO2,
CH4, H2, O2, C2H2, C2H4, and CnHm, automatically calculate and
display the calorific values of gas and biomass gas, and can
replace the combustion - method calorific value instrument.
- High safety factor with an explosion - proof grade of Ex d IIC T4
Gb.
- Low maintenance and operation costs. It can monitor and display the
system operation status in real - time without the need for manual
attendance, greatly reducing maintenance costs.
- Intelligent data management. Data can be transmitted to the
superior centralized control system through multiple interfaces,
providing real - time basis for remote monitoring and on - site
process adjustment.
