Abstract

Embodiments herein relate to media separated heat exchanger for use in a system for calcination of lime mud. The media separated heat exchanger is arranged to heat lime mud by heat transfer from hot gas mixed with calcium oxide. The media separated heat exchanger comprises an outer shell with one or more tubes arranged inside the shell. Into the tubes a first medium for heat transfer is fed and flows during heat transfer, and a second medium for heat transfer flows outside the tubes. The first medium is lime mud and the second medium is hot gas mixed with calcium oxide. The media separated heat exchanger is provided with an arrangement for providing a turbulent flow of the medium flowing inside and/or outside the tubes.
