In a directfired rotary kiln, the burner is situated inside the kiln body, that is, inside the reaction chamber. The material is heated directly by the burner flame and the stream of hot gas produced by the burner. These kilns are usually lined with refractory (heatresistant) material so that they can be operated at higher temperatures than kilns with plain metal tubes. Directly fired kilns ...

Indirectfired kilns are externally heated in order to keep the material and products of combustion separate. Material, heated through direct contact with the shell, rolls along the drum's interior, exposing fresh material as it tumbles to promote even heat distribution throughout the bed, sometimes with the help of bed disturbers. 3D Model of a FEECO Rotary Calciner. .

Due to the horizontal flow in the rotary kiln, the particles follow, in contrast to the use case in the calciner, rather a ballistic trajectory (Fig. 3 and 4). This can indeed be extended by making use of certain properties of the gas flow, but this only to a small extent. The best leverage for optimization is logically found in the early ignition of the alternative fuel. This can be achieved ...

An indirect rotary kiln is best for this appliion, because the volatile chemicals may be combustible. The indirect kiln would supply the heat for desorption, without the material coming into direct contact with the flame. ORGANIC COMBUSTION Organic combustion is the thermal treatment of organic waste with the intent of reducing mass and volume.

a rule, the kiln feed precalcined in the preheater and calciner still contains a certain amount of CaCO3 that will be calcined to form CaO in the kiln. When kiln feed undergoes the high temperature zone in the rotary kiln, a series of chemical and mineralogical reactions occur. The components of feed (such as calcium oxide, alumina, ferric oxide, silica, and other metal .
