Numerical investigation of the impact of coating layers on …

The objective of the study presented is to investigate both, the impact of coating layers on RDF combustion and the clinker phase formation in a generic rotary kiln. Therefore, for the first time, the models developed for RDF and coating layers as well as a newly proposed method to implement the clinker bed, are combined to form a comprehensive ...

Counteracting ring formation in rotary kilns

Avoiding the formation of rings in rotary kilns is an issue of primary concern to the cement production industry. We developed a numerical combustion model that revealed that in our case study rings are typically formed in zones of maximal radiative heat transfer. This local overheating causes an overproduction of the liquid phase of the granular material, which tends …

Rotary Drum Furnace to Investigate the Performance of …

In addition, the formation and stability of coating layers can be studied. 1 Introduction In Germany alone, 23 Mt cement clinker are being produced in rotary kilns annu-ally [1]. The production process of cement clinker relies heavily on refractory linings that protect the structure of the rotary kiln from the hot clinker and hot gases in

RING AND SNOW BALL FORMATION IN THE KILN

rotary kiln. For instance, the lime content we have in the meal, loss on ignition free, never coincides with the lime content in the clinker. The lighter lime particles are easily carried by the gases, while silica, iron oxide and alumina particles follow down the kiln into the burning zone. Depending on the degree of segregation, excess liquid may

that many kilns suffer from, i.e., the formation of rings. Kiln Fouling and Ring Formation Reaction materials flow through the kiln because of the slope and rotation speed of the kiln. Apart from a thin coating that is applied to the refractory during start-ups there should be no accumulation of material in the kiln. Fouling occurs
