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 .

From the above table, it can be seen that, except for the Fukas kiln, the cost of producing active lime in the annular shaft kiln is the lowest. It should be noted that the above data is the product cost when using recycled gas from within the steel plant. For example, if a rotary kiln uses coal powder as fuel, the cost of lime per ton will ...

Comparison of Lime Kiln Types. Each type of lime kiln has its unique characteristics that determine its suitability for different applications. Batch or intermittent kilns are ideal for small-scale production and are simple to operate, while continuous or annular kilns are ideal for larger-scale production and produce high-quality quicklime.
