single-unit fluidization
Thread Content
What are the common phenomena that occur during the fluidization of individual units in an accident?
In single-bed fluidization, it is still the catalyst that suffers the most damage. Loss from running + damage + inactivation. The bed temperature needs to be maintained by injecting combustion oil. The operation mode of single-unit fluidization + dead bed can be considered. Start the standby fan to achieve single-unit fluidization; once the temperature rises, stop the standby fan and seal the bed. This process is generally carried out once every 24 hours. During the bed shutdown period, the double-acting slide valve can be heated to reduce temperature losses, and the draft from the chimney can also be used to facilitate the flow of flue gas.
