Optimization of calciners in the cement industry Cement

Feb 01, 2010 Summary: In recent years, most developments in burning systems for the manufacturing of cement have concerned the calciner. Apart from its original function of calcining the raw meal, the system was given increasingly often the task of burning the highest possible proportion of secondary fuels, which are often supplied in large pieces.

Precalciner Calciner In Cement Plant, Cement Calciner

Precalciner, also known as cement calciner, is a kind of high-efficiency direct combustion solid-gas heat exchange cement equipment. It disperses and suspends cement raw meal powder in airflow, making fuel combustion and calcium carbonate decomposition happen in a

Calciner messergroup

The calciner is usually to be found in the form of a cyclone pre-heating tower (formerly LEPOL kiln). The raw meal is heated in this counter-current heat-exchanger. The energy for the calcination reaction must also be introduced here, or via a burner in an additional pre-calciner. Modern pre-calciners already use up to 100% replacement fuels.

The cement kiln Understanding Cement

Basic principle of a precalciner cement kiln. Since meal enters the kiln at about 900 C, (compared with about 20 C in the wet process), the kiln can be shorter and of smaller diameter for the same output. This reduces the capital costs of a new cement plant.

This precalciner can be considered an enlarged kil

The cement kiln Understanding Cement

Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln.

Calcination kinetics of cement raw meals under various CO2

In a highly integrated CaL arrangement, the pre-calciner of the cement plant is replaced by an oxy-fired calciner. 21,29,32 A large fraction of the calcined solids is sent to the kiln and the remaining solids circulate to the carbonator to react with the CO 2 of the flue gas exiting the kiln 30 (see Fig. 1).
