Examples
-
After removal of “red mud” (the insoluble part of the bauxite) and fine solids from the process liquor, aluminum trihydrate crystals are precipitated and calcined in rotary kilns or fluidized bed calciners to produce alumina (Al2O3).
-
Although the reduction in specific heat consumption by adding pre-calciners to the suspension pre-heater-kiln system is modest, namely, about

A significant reduction of specific heat consumption in rotary kilns is achieved by using modern dry process kilns with suspension pre-heaters or more advanced kilns with both suspension pre-heaters and pre-calciners, where the heat of the exhaust gas of the kiln is used for pre-heating the kiln feed.

Further developments in clinker production have been achieved by the introduction of the cyclone suspension pre-heaters with pre-calciners (4).

-
Therefore, it is possible to feed up to 75 per cent of the fuel into the secondary furnace in kilns with pre-calciners (in practice normally up to 60 per cent is burnt in the pre-calciner).

-
Widespread opportunities for using low-grade fuels for clinker burning were opened up by the development of systems with cyclone pre-heaters and pre-calciners.

This has led to better heat economy, increase in kiln capacity and, particularly in connection with the application of pre-calciners, making it possible to use smaller kilns for a given capacity.
