Re: low pressure high efficiency cyclones
thanks sir
that i needed ? but i whant know how to make cyclone performance efficeicy?2)is the cylone efficieny constant for all time or it will change with operation?and how to design preheater fan ,as we know the are relation between cyclone pressure drop and fan

I take this as separation efficiency of the cyclone the most practical method to determine this would be collecting samples at riserducts & mealpipes then analyse it for "PSD" and draw tromp curve and then report weighted average of efficiencies but practical problem is How will you collect samples for lower cyclones at 800-950oC?
2)is the cylone efficieny constant for all time or it will change with operation?
Cyclones Being a static equipment the separation efficiency remains more
or less unaltered with operational conditions unless it is not operated
with in designed conditions (designed capacity)
how to design preheater fan ,as we know the are relation between cyclone pressure drop and fan
Now about designing a preheater fan, a mechanical adept would be appropriate. however i feel it's more of a seclection, once flow a0,density and desired pressure is known as fans are standardised for given process conditions,
ex:Density 1.2 kg/m3 , at 80m3/s and 180000Pa
Fan HAF 250, with shaft power of 1700 KW and total weight of 12500 kg is required for detailed calculations please refer here http://www.flsmidth.com/en-US/News+and+Press/Brochures+and+Articles
