THE PURPOSE of this paper is to educate the younger generation of
engineers currently working in the sugar industry and to help them avoid
certain pitfalls that are generally associated with boiler induced draft fan
selections. We have been asked by the engineering sections of many
sugar mills, both in Australia and overseas, to write a paper so they can
avoid consequences of poor boiler induced draft (ID) fan selection.
Knowledge and examples put forth in this paper are a result of many
years of experience working with industrial fans and their applications
and, as a result, can provide valid reasons as to what type of fan is best
suited for each application and why.
