KHD signs next Pyrorotor contract in South Korea
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 third 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 a new Pyroclon R® calciner, as well as a Pyrorotor®, 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
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.
