Cyclone performance and optimization
The objectives of this project are: to characterize the gas flow pattern within cyclones, to revise the theory for cyclone performance on the basis of these findings, and to design and test cyclones whose dimensions have been optimized using revised performance theory. This work is important because it successful completion will aid in the technology for combustion of coal in pressurized, fluidized beds. During the past quarter, we have (1) significantly strengthened our data set for radial and tangential velocities through the cyclone, (2) developed a technique to filter noise from the radial velocity measurements, (3) modified our Model program so that we can now use our flow field measurements to predict cyclone collection efficiency for particles of various sizes. 3 figs.
