Discussion on gasification fluidized bed issues
Thread Content
Hello, everyone: I am working on gasification, and there are a few issues I’m not quite sure about. I hope those who know the answer can give me some guidance. Thank you! ! ! 1. Is there a static bed height during the operation of a gasification fluidized bed? If so, what is the typical value for this static bed height? What factors influence its value? 2. How is the height of a gasification fluidized bed calculated? Is it related to the expansion ratio? But is the expansion ratio an assumed value or can it be determined through calculation? 3. In fluidized bed operation, there is a concept called total air volume. Does anyone know what that means?
First of all, I’m not sure if by \"static bed height\" you mean the height of the stationary material layer; this is related to the pressure drop within the bed. In other words, it is associated with the particle concentration and the total amount of material present in the bed. As for the other two issues, I suggest you consult a basic book on fluidization – it’s quite simple, but explaining them in detail would require quite a bit of writing, haha~ Good luck to you!
