Application of acoustic agglomeration to hot gas clean up in pressurized fluidized bed combustors
Abstract
An experimental investigation has been performed to verify the theory of aerosol deposition and agglomeration in high-intensity acoustic fields. A computer program has been developed to predict the time variation of aerosol properties. Using a laboratory scale transmissometer for the continuous light-opacity measurements, separate experimental runs have been directed to investigate the effects of I, f and M. In the operating range of I = 160-164 dB, f = 500-2200 Hz and M = 10-30 gm/cu m, the data agree with the theoretical results. It is also shown that the standing-wave operation is more effective than the traveling-wave operation.
