1 Annular shaft kilns Annular shaft kilns were developed in the 1970s to produce soft-burned lime in a single shaft kiln. To achieve this, a co-current burning zone is estab - lished in the lower part of the kiln. Compared with a Parallel Flow Regenerative (PFR) kiln, the shaft ge-ometry is much more complex. This can be seen in Figure 1 .
