Meal Drop to Kiln in Cement Preheater System

This video, courtesy of aixprocess GmbH, comes from a recent project for a cement plant in Europe where the end client suffered from high preheater exit gas temperatures. Rather than simply modifying the top-stage cyclones to address the local thermal concern, a more holistic analysis also detected massive meal dropout from the meal box in the kiln riser to the bottom stage cyclone, which was caused by an undesirable local gas-particle flow behavior. Ultimately this was determined to also be the root cause for the elevated preheater exit temperatures. After performing digital twin-based engineering analysis, aixprocess developed a plant-specific and low budget modification, which could be implemented quickly during an already planned shutdown.
This video shows how the meal-drop to the kiln inlet shelf has been massively reduced through a simple modification, informed by Barracuda Virtual Reactor simulation. After plant restart, the actual operation showed an immediate and sustainable drop-in kiln exhaust gas temperature by 20°C.

Sir will you please guide me on How can I build my career in the CFD designing

Can you magnify the modification part?

This video shows the detail level that was authorized for public release. The modification was designed with the end client's specific issue and plant in mind, and may not be something recommended in general, but plant-specific analysis and virtual testing of changes are available from CPFD and several of our local international business partners.
