Document Type and Number:
Japanese Patent JP2593569
Kind Code:
B2
Abstract:
In the heat treatment of lime mud, the lime mud to be introduced to a lime reburning kiln is dried in a penumatic drier by flue gases from the lime reburning kiln in order to regenerate the lime contained in the mud. Prior to drying, the lime mud is thickened in a drying filter to a dry solids content of over 75%, preferably to approximately 80%. In this way, the lime reburning kiln can be made approximately 30% shorter than conventional kilns, and the apparatus is simpler than the conventional apparatus provided with a pneumatic drier.
