Filtration for Flue Gas Analysis and CEMS

Three Steps of CEMS: 1st Step: Gas Sampling 2nd Step: Gas conditioning and treatment 3rd Step: Measurement/Calibration In first step, the function is to get sample gas and forward to 2nd step for treatment. During this step, it cannot block the probes and cannot result condensation of moisture. So a filter online back flushing should be equipped in this part. The filters to be used: 1, Filter is used to ensure the stability of system and reduce the maintenance 2, Filtration Grade: usually 2 or 3 micron 3, Temp. is around 0-180 deg C 4, Back flushing gas is heated, impulse flushing 5, Filter Material: Titanium Sintered, SS316L Sintered, PTFE sintered, Ceramic Membrane and so on 2nd Step Gas Treatment: The coarse filters and the liquid particle filters The coarse and fine cartridge can filter the small particles in the gas and acid aerosol things to better protect the instruments. The micron can be 0.1micron, filtration rate can be up to 99.99%, two layers can be 99.9999%
