IKN was contracted for the engineering, supply, and installation of an upgraded pyro line reaching 4000 tpd, from raw meal feeding to clinker discharge. The contract included integration engineering, supply, and installation of add-on components for the raw meal grinding plant. The upgraded kiln line features state-of-the-art technology in order to reach the targeted production level and to comply with future emission limits. The new production line comprises a two-string, 5-stage preheater tower with inline calciner and Fire Bed Combustor for coarse RDF. IKN’s most modern preheater and calciner design ensures minimum pressure drop at maximum performance and high efficiency. The kiln line has been designed for maximum use of a broad range of alternative fuels.
