Halla Cement awards upgrade project to KHD

South Korea: Halla Cement has awarded a supply and engineering contract to Germany-based KHD Humboldt Wedag for an upgrade of line 2 at Okke plant. KHD will supply a new Pyroclon R type calciner, with a Pyrotop type mixing chamber, and a 4.2m x 15m Pyrorotor type combustion reactor. Other equipment being provided includes: a Pyrobox type coal firing system for process start-up and operation balancing; replacement of stage five cyclones with new high-efficiency cyclones; and a new kiln inlet chamber with orifice. Erection and commissioning of the modernised production line is scheduled for the first quarter of 2024.

This latest project marks the second installation of a Pyrorotor at Halla Cement’s Okke plant. The installation of line 3 at the site is currently ongoing with commissioning scheduled for the first quarter of 2023. Overall, this will be KHD’s ninth installation of a Pyrorotor in South Korea.

The Pyrorotor has been promoted to cement plants as a way of using low-quality alternative fuels with minimal pre-processing. It offers a thermal substitution rate of over 85% and will also allow the Okke plant to reduce its NOx emissions. The installation of the new Pyroclon R type calciner and the high-efficiency cyclones in the lowest preheater stages will also provide the production line with an increase in efficiency due to an overall pressure drop reduction in the entire preheater.
