Reasons for increased vibration in the smoke extractor
Thread Content
Recently, the levels of heavy metals in the catalyst are too high: nickel at 13,000, calcium at 7,676, copper at 3,000, and iron at 5,400. Does this have an impact on the smoke extractor? Thank you
The calcium content may affect the catalyst. Does such a high calcium content in your catalyst not affect fluidization?
Temperature and atmospheric humidity have some impact on vibration! The magnitude of the load also has an impact on it.
The most direct cause of increased vibration levels in the smoke extractor is the presence of catalyst dust in the flue gas; an increase in this dust amount exacerbates the wear of the rotor blades as well as blade scaling. When the dynamic balance during operation is disrupted, the shaft vibration levels rise. The length of the stable operation period of the smoke machine is mainly influenced by it.
An increase in heavy metal content primarily damages the structure of the catalyst, leading to an increase in dust formation; this in turn increases wear on the smoke extractor, thereby affecting its proper operation! There are many relevant articles on the forum; it is recommended that members search for the keyword “fouling of smoke extractors”. I hope this will be helpful to you!
There is dust in the flue gas, and the steam from the rotor must not contain water. Once, low steam temperature along with water content caused the rotor’s dynamic balance to be disrupted, which led to an increase in vibrations
The level of heavy metals is too high; therefore, the amount of reagent used must be significant. Both units are likely to experience reagent depletion, and if the regenerator runs out of reagent, it will affect the flue gas treatment equipment. It is recommended to replace the balancing agent as soon as possible, in order to reduce the total content of heavy metals on the catalyst to below 10,000, thus ensuring the stable operation of the subsequent three-spinners and flue gas treatment equipment
Test the calcium and iron content in Sanxuan fine powder. If the calcium content is greater than 12,000, there is a risk of scaling.
