26 • Rotary reactor for very coarse secondary fuels and secondary raw materials • Ø 3,4 m x 10 m • Retention time, Material: ~10 min • Highest flexibility for almost any type of unprepared AF because of long retention time • Reduced primary fuel cost due to highest thermal substitution rates • Future-proof for changing fuel scenarios • High reliability due to robust and sturdy design originated from KHD rotary kiln parts • Easy to operate and maintain • Retrofittable for any existing plant • Lowering carbon footprint by reducing fuel rel. CO 2 KHD has commissioned many Pyrorotor® in various Figure 4: 1 st PYROROTOR ® installed in Austria cement plants across the world. The substitution rate at calcinedr has gone up to 100%. Some of the references from the past few years are summarized in the table below.
