In August 2015, IKN was awarded the contract for the engineering, supply and installation of a complete 4000tpd pyroline – from raw meal feeding to clinker discharge – at HeidelbergCement's Burglengenfeld plant in Germany.
Included in the scope of supply are integration engineering, supply and installation of add-on components for the raw meal grinding plant. The upgraded plant will feature state-of-the-art technology in order to comply with the targeted production level and future emission limits. The new line will consist of a two-string, five-stage preheater tower with inline calciner.
IKN’s most modern preheater and calciner design will ensure minimum pressure drop at maximum performance and high efficiency. The kiln line will be optimised for maximum use of a variety of alternative fuels.
"Among several features will be a tertiary air duct damper which has proven successful operation for more than three years with outstanding reliability and performance. Another essential component of the plant is the Pendulum Cooler® featuring high reliability at low maintenance and operational costs. The Pendulum Cooler® by design allows recirculating bypass gas into the recuperation zone in order to boost cooler efficiency," said IKN.
