ABSTRACT:
A two-zone lime mud calciner is provided for processing lime mud from kraft pulp recovery operations. A conveyer is employed for conveying lime mud horizontally through the calciner. The first zone and second zone of the calciner each contains a dielectric hysteresis heating device for first drying the lime mud in the first zone and then decomposing the dried lime mud to lime and carbon dioxide. A co-current flow of purge air removes steam generated in the first zone and a counter-current flow of purge air removes carbon dioxide generated in the second zone with a vent being provided adjacent the upstream and of the second zone.
