backward-curved v.s. radial in scrubbers

backward-curved v.s. radial in scrubbers

backward-curved v.s. radial in scrubbers

(OP)
Up to now, we have used radial type centrifugal fans in our scrubbers (blades extend from the hub straight out).  We want to evaluate the use of backward-curved blades for our scrubber ID fans, could somebody point me some literature on the subject?  I understand that radial fans are less prone to solids build-up, but I recently visited a plant whose scrubber uses backward-curved fans, and they are doing OK, with smaller fan motors for comparable applications.

Also, is there a rule of thumb for approximately how much less power you need on a particular application when using a backward-curved instead of radial fan? What about fan speeds, in general a backward would work faster or slower than a radial, for comparable sizes?

Last, any references of good fan suppliers for scrubbers or corrosive/abrasive environment applications?

Thanks a lot for your help.
