Impact of coating layers in rotary cement kilns: Numerical ...

2020-3-1  In addition, changes in radiative heat flux and temperature may also impair clinker properties. Hence, in summary it can be said that coatings in rotary cement kiln, when growing to a certain size, have a significant impact on all processes within the furnace and have to be considered for a correct numerical description of the system.

2021-1-1  Together with the shift in gas phase temperature towards the kiln inlets, this leads to a faster temperature increase of the clinker bed compared to the reference case. The cause of this phenomenon is the increased residence time of the clinker near the kiln inlet, as the coating leads to material accumulation in this area.
