IBU-tec Pyrolysis in Rotary Kilns

At IBU-tec we can perform both types of pyrolysis. Indirectly fired rotary kilns are 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 fired rotary kilns by running the flame deliberately with sub-stoichiometric oxygen levels.
