(292d) Cyclones a la Zenz?
AIChE Annual Meeting
2019 AIChE Annual Meeting
Particle Technology Forum
Special Session: Celebrating Career Accomplishments of Fred Zenz (Invited Talks)
Tuesday, November 12, 2019 - 9:15am to 9:40am
The Zenz method of characterizing cyclone operation consists of taking the particle size distribution (PSD) in the carryover (entrained) solids from a fluidized bed and subdividing the PSD into several âcutsâ. Each âcutâ is then analyzed to determine if it can be collected by the cyclone relative to a collection model. The model is then used to calculate cyclone efficiency at extremely low loadings, and the effect of loading on cyclone efficiency is predicted.
Cyclone pressure drop is determined by summing several individual components of the pressure drop. A little-known aspect of cyclone pressure drop is that as solids loading increases from near zero loading, cyclone pressure drop initially decreases as solids loading is increased. The Zenz method cyclone analysis takes this unique characteristic of cyclones into account.
In this presentation, the Zenz method of cyclone analysis will be described in detail.
