Lime kilns, shaft furnaces, rotary kilns and fluidized bed reactors can all be called calciners. Apart from lime and cement manufacture calciners are also used for processing bauxite, gypsum and petroleum coke. In all cases a hot dust laden gas stream must be cleaned prior to discharge, usually up a tall chimney.
