FD FANS
(OP)
Hi all,
I am currently working with a FD Fan for Co-Incinerator application. Kindly provide your views on the possibility of reverse rotation of such fans and how to prevent the reverse rotation? Further, would like to know what happens if the FD fan rotates in reverse direction for the subject application. Thanks in advance.

Some pumps have anti-rotation clutches to prevent just such problems.

Venkat162,
Have a look at cam clutches and sprag clutches to stop the fan rotating in reverse, or if you can't get a reliable one, then a DC injection brake might be an option. If the fan already has a VFD for process reasons then it should be able to either catch the windmilling fan during start or actively hold it at zero speed.
