Unbalanced fan
Unbalanced fan
(OP)
We have a customer that is having problems with their ID fan coming unbalanced. The system has been running for only about a year and we are about to balance and replace the bearings for the third time. The pulleys/belts and everything appear to be in order and properly alligned.
The system runs about 8000acfm @ ~375F. We are burning wood.
Any thoughts? Our fan manufacturer has not been helpful.

I'm just wondering if the fan is condensing creosote.

I would be very surprised if the flue gas temperature ever gets below 350F. To be honest, we were thinking the temperature may be too high, increasing the volume and overloading our fan.
Having said that though, we heard that the fan was cleaned and it was running much better now. We have seen problems with flyash buildup problems before but nothing significant or as frequent as this job site. Not sure why we seem to be having such a problem with build up here though.

Maybe I'm overlooking something...

I am thinking of an expression Work = flow * delta P [cannot remember if there was a constant in it].
If I'm wrong, tell me, I am just not seeing it.
RE: Unbalanced fan
Work is force x distance and has an equivalence to energy,
RE: Unbalanced fan
Power = volumetric flow * pressure difference
Also, my pressure required to maintain draft will go up as my volume increases.

Like I said, I am not a fan expert.

I actually wrote more in my last post, then accidently deleted it, then it was time for lunch...
These may help.
