    Rotary kilnincinerators usually have a length-to-diameter (L/D) ratio between 2 and 8.Rotationalspeeds range between 0.5 and 2.5 cm/s, depending on thekilnperiphery. High L/D ratios and slower rotational speeds are used for wastes requiring longer residence times. The kilns range from 2 to 5 meters in diameter and 8 to 40 meters in length.

    At IBU-tec we can perform both types of pyrolysis. Indirectly firedrotary kilnsare predestined for pyrolysis because the heat source is isolated from the material and we can easily regulate the gas atmosphere. In principle, it is also possible to perform pyrolysis in directly firedrotary kilnsby running the flame deliberately with sub-stoichiometric oxygen levels.

    In the reaction process, the state of the material in therotary kilnand the reaction process has a great relationship. When thedegreeof reaction is 0 ~ 40% and 70% ~ 80%, the material is corrosive to the reactor. Therefore, how to design therotary kilnto avoid corrosion to extend the service life of the process has been one of the key issues.
