Extractive Flue / Stack Gas Analyzer

Gas Analyzer OMGA-2000 UV online monitoring gas analyzer is a one-site installation gas analyzer that is developed after years of teaching and design on online gas analysis instruments. It can monitor gas parameters including the concentration of SO2, NOx, O2, Dust, Humidity, Temperature, Flow and etc. It is widely applied to tall gas emission monitoring and process analysis in many fields, including coal-fired power plant, waste to energy plant, cement factory, glass factory, lime factory, sinter coke oven, DeSox process, and DeNox process Flow Principles – Under the work of high temp sampling pump, the gas passes through sampling probe (filter cartridge included), ball valve, heating tracer, secondary filtration, and then enters into UV analysis module and finally be drained. By adopting 150°C high temp heat tracing for the whole process, it can effectively prevent SO2, HCL and other gas detected gases from being dissolved and loss for condensated water. By controlling back blowing valve impulse, the system can regularly back-below the filter cartridge of the sampling probe and close the ball valve that prevents high-level dust from blocking the filter cartridge. The Online Flue Gas Analyzer supports auto/manual calibration(zeroing and span 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 temperature control is invalid.
