CFD Modeling of Calciner​

Efficient calcination is essential for stable kiln operation and product quality. The calciner, positioned in the riser duct between the kiln inlet and bottom stage cyclone, plays a critical role in distributing raw materials evenly to prevent accumulation and enhance residence time. Using CFD simulations, the combustion process was studied under conditions of kiln exhaust gas mixed with tertiary air.

The objective was to evaluate calcination efficiency and predict exit gas composition with a reduced tertiary air inlet. The analysis provided valuable insights into airflow, combustion, and raw material distribution, enabling design and operating improvements. Learn how CFD supported optimization of calciner performance in this case study.
