Title:
METHOD AND APPARATUS FOR PNEUMATIC DRYING OF LIME MUD
Document Type and Number:
WIPO Patent Application WO2006104775
Kind Code:
A3
Abstract:
Method and apparatus for pneumatically drying thickened lime mud and feeding the dried thickened lime mud to a lime reburning kiln. The thickened mud is pneumatically dried via the action of flue gas emanating from the lime reburning kiln. The dried, thickened lime is separated from the flue gas in a cyclone separator. A process loop controller determines the temperature of the separated lime and, in response, controls the feed rate of lime fed to the pneumatic dryer to ensure that the dryer possesses the requisite latent heat needed to dry thickened lime therein. In one embodiment, the feed rate of lime fed to the thickener is adjustably controlled which, in turn, adjustably varies the flow rate of the thickened mud to the dryer.
