Topic: Re: What are the advantages of falling film reboilers and thermosiphon reboilers?

There is a good discussion of the various styles of reboilers in Hewitt, Shires & Bott – “Process Heat Transfer” Chapter 14.  Falling film evaporators are also covered in Chapter 15.   Falling film units typically utilize small temperature differences and avoid nucleate boiling so that fouling associated with this type of boiling is avoided.  Thermally sensitive liquids are also frequently evaporated in this way.
