Extractive Flue or Stack Gas Analyzer

The gas analyzer OMGA-2000 UV online monitoring gas analyzer is a one-site installation gas analyzer that has been developed after years of research and design on online gas analysis instruments. It can monitor gas parameters including the concentration of SO2, NOx, O2, dust, humidity, temperature, flow, etc. It is widely applied to tall gas emission monitoring and process analysis in many fields, including coal-fired power plants, waste-to-energy plants, cement factories, glass factories, lime factories, sinter coke ovens, the DeSox process, and the DeSox process flow principles.

Under the work of a high-temperature sampling pump, the gas passes through the sampling probe (filter cartridge included), ball valve, heating tracer, secondary filtration, and then enters into the UV analysis module, where it is finally drained. Adopting 150°C high-temperature heat tracing for the whole process can effectively prevent SO2, HCL, and other detected gases from being dissolved and lost in condensed water. By controlling the back-blowing valve impulse, the system can regularly back below the filter cartridge of the sampling probe and close the ball valve, preventing high-level dust from blocking the filter cartridge.

The Online Flue Gas Analyzer supports auto or manual calibration (zeroing and spanning calibration); the measuring flow path needs to be closed when calibration is working. A pressure transmitter can be used to compensate for the measuring valve and also to check if the probe is blocked. Secondary filtration is adopted to protect the UV analysis module to ensure it will not be polluted by flue gas and dust when the probe is leaked or the temperature control is invalid.

Gas analyzers are analytical devices that measure the concentration or quality of a selected gaseous compound within a mixture of multiple gases. They're used across a wide range of industries—such as agriculture, manufacturing, and waste management—to help facility owners and managers monitor gas levels in their operations to make sure the numbers are within a suitable range for the security of employees and therefore the quality of products or processes.

FEATURES :
