Two-fluid nozzle vs rotary atomization for dry-scrubbing ...

An outline of the basic process for dry-scrubbing of flue gases is given. The paper makes a comparison between the two-fluid nozzle spray drier/absorber and the rotary atomizer design. The conclusion is that the two-fluid nozzle system is more cost-effective for applications up to 78.8m/sup 3/S in size with a 70% SO/sub 2/ removal requirement.
