During the project, the existing preheater will be modernised with the installation of new PYROCLON R® calciner, as well as a PYROROTOTR®, a state-of-the-art rotary combustion reactor for low-processed alternative fuel.
The overall projet scope consists of the following equipment and upgrades:
• PYROCLON R calciner with PYROTOP® mixing chamber
• PYROROTOR alternative fuel combustion reactor
• PYROBOX® coal firing system for process start-up and operation balancing
• Replacement of stage five cyclones with new high-efficiency cyclones for calciner connection and an overall pressure drop reduction
• Bypass mixing chamber installation
• A new kiln inlet chamber with orifice.
