The kiln plant of the Stromberg lime works, which was still operating until 2010, consisted of two annular shaft kilns (no. 1 and 2), three lime shaft kilns (no. 3, 4 and 5), a passenger lift and a bucket lift. The riveted kilns were 25 m high and had an outside diameter of m or m.
A lime kiln is a kiln used to produce quicklime by the calcination of limestone (calcium carbonate).The chemical equation for this reaction is:. CaCO 3 + heat → CaO + CO 2. Limestone is poured into one side of the kiln, it is then heated up with hot air and quicklime [Calcium Oxide] comes out the other end.
In order to facilitate the design and the customising of lime shaft kilns and in order to better understand phenomena like surface sintering, further research work is still required as there is still an unanswered key question: “What material properties cause surface sintering according to section and what countermeasures can be ...
