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 its successful completion will aid in the technology for combustion of coal in pressurized, fluidized beds. During the summer we have made progress in two areas. First, we have finished developing techniques for characterizing the flow field within our cyclone. We have now used these techniques with a Stairmand high efficiency cyclone to show the radial as well as the tangential velocity distribution. Second, we have conducted a study to determine the effect of particle concentration on collection efficiency. Results of progress in both areas are discussed. 4 figs.
