Co-firing of Alternative Fuels in Cement Kiln Burners ...

The model calculates temperatures in the gas phase and clinker bed through the kiln and the clinker composition is given as output. Thus, the impacts of co-firing different alternative fuels can be studied. It is also possible to explore methods to reduce the negative effects of co-firing.The model was used to study the influence of SRF co ...

Clinker Production | Clinker Plant | Cement Plant Equipment

In the rotary kiln, the carbonate is further rapidly precalcined and a series of solid phase reactions occur to form minerals in the cement clinker. As the temperature of the material increases, the mineral becomes a liquid phase and reacts to form a large amount (clinker). After the clinker is fired, the temperature begins to decrease.

Cement - HORIBA

Cement is made by heating limestone with small quantities of other materials such as clay or sand to 1450°C in a kiln. The resulting 'clinker', is then ground with a small amount of gypsum into a powder to make Portland cement. The most common use for Portland cement is in the production of concrete – a composite material consisting of ...

In the clinker production of dry process, the calcined clinker is quenched in a grated cooler or a rotary cooler after being discharged from the kiln. Because there are two processes of liquid phase condensation and mineral intersection in the clinker cooling process, the cooling process will have a certain degree of impact on the clinker quality.
