Cyclone Design

Basic parts of the preheater are cyclones with low pressure loss. Additionally, the LUCY Preheater’s top stage cyclones are designed for maximum dedusting efficiency.

The number of cyclone stages determines the specific fuel consumption. It is a compromise between the efficiency of the preheater and drying requirements of the raw meal.

First stage cyclones

Cyclones with a high separation efficiency and low pressure drop are employed as top stage cyclones, where a separation efficiency of 95-97% is required.

System cyclones

The cyclones at the lower and bottom stages are specifically designed to ensure low pressure loss.
