Lime Kilns in Chemical Kraft Recovery

A lime kiln uses heat, motion, and airflow to convert lime mud to lime, or in chemical terms, calcium carbonate to calcium oxide. This process is referred to as "calcining". The most common lime kiln designed found at kraft pulp mills is the rotary lime kiln.


ROTARY KILN CHAIN SYSTEMS At the cold end of the kiln, the relatively low gas temperature hampers heat transfer. To improve this, a section of chain is hung from the shell in this part of the kiln. This chain is made up of links that are typically ¾ in. by 3 in. (1.9 cm x 7.6 cm). Hangers attach lengths of this chain directly to the kiln shell
