Annular shaft kiln for lime burning with kiln gas ...

2008-05-01  Lime burning in annular shaft kilns belongs among processes that are more sensitive to changes in air excess ratio, e.g. processes in burning devices in which a certain working fluid is heated or evaporated (e.g. steam boilers). The reason for this lies primarily in the chemical nature of the lime burning process, the decomposition of CaCO 3.
