New and innovative Maerz PFR lime kiln for Kalkfabrik Netstal in Switzerland

摘要

Maerz Ofenbau AG built a new PFR lime kiln with a direct cross-over channel for the production of quicklime with a very low residual CO_2 content and very high reactivity in Kalkfabrik Netstal/Switzerland. The aftercooler prevents the otherwise unavoidable recarbonization in the cooling zone and enables the production of lime with a residual CO_2 content of 0.5% in a PFR kiln with direct overflow channel.
