How to operate the catalytic device to ensure proper functioning of the catalytic flue gas processor
Thread Content
How should a catalytic device be operated to ensure proper functioning of the catalytic flue gas treatment system? What details need to be paid attention to on a regular basis? My personal opinions on these matters are as follows; I’m not sure if they are correct, so I hope experts can provide guidance: 1. Pay attention to the catalyst content and particle size in the flue gas; 2. Pay attention to the rate of temperature increase and decrease during startup and shutdown; 3. After maintenance, make sure to remove any catalyst or impurities from the inlet pipelines; 4. During maintenance, increase the clearance between various sealing elements according to the specifications, pay attention to any deformation of the casing and the secondary static blades, as well as the alignment between the casing and the bearing box. Avoid using metal-wrapped gaskets for the inlet flanges, as well as inner and outer metal-wrapped gaskets. Also, pay attention to the cold-state tension values of the inlet and outlet pipelines, as well as the cold-state stress levels in those pipelines; 5. Regarding the steam used for cooling the rotor disk, try to minimize its usage and keep the rotor disk temperature within an appropriate range; 6. Keep the flue gas temperature within the optimal range; 7. Strengthen condition monitoring to have a clear understanding of the system’s status; 8. Reduce the amount of water vapor in the flue gas

You are referring to a catalytic device, so you need to take into account the factors affecting the entire system. Such as the control of regenerator pressure, flue gas flow rate, and flue gas temperature ； The efficiency of the centrifuge, etc.
As for the smoke extractor itself, there are no major quality issues; the common problem is catalyst fouling, which in China is likely due to problems related to the manufacturing process. It is important to pay attention to the catalyst content and particle size in the exhaust gases
Parameters such as the vibration level, rotational speed, and seal steam differential pressure of the flue gas engine – actually, regarding the flue gas engine itself, what you’ve mentioned is already very comprehensive!
