KHD signs next Pyrorotor contract in South Korea

Cologne, Germany, February 14, 2020 – Asia Cement Company Ltd (Korea) awarded Humboldt Wedag GmbH, a subsidiary of KHD Humboldt Wedag International AG, with a supply and engineering contract for the modernization of its 3rd clinker production line located close to Jecheon-si, Korea. The target of the upgrade project is to increase the alternative fuel substitution rate to above 85% of calciner fuel, as well as the reduction of NOx to satisfy local emission limits.

KHD’s scope includes the engineering and supply of mechanical equipment for the clinker production as well as electrical equipment for the overall modernization of the production process. During the project, the existing preheater will be modernized 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 5 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

The commissioning of the modernized production line is planned for the first quarter 2021. With this reference, KHD continues to demonstrate its expertise and position as a market driver for highly-reliable and energy-efficient pyro solutions.
