A TEC to upgrade chlorine control system

Published by
World Cement,

LafargeHolcim has awarded Austria-based A TEC Group a contract to upgrade its existing chlorine control system at the Kujawy cement plant in Poland.

The Kujawy plant uses A TEC’s REDUCHLOR bypass to reduce chlorine content in the kiln. Based on computational fluid dynamic and process simulations, the existing bypass rate will be increased from 5% to 10%. The increase will be achieved without needing to upgrade equipment, such as the bypass filter and bypass filter fan.

“Modern suspension preheater kilns frequently face substantial problems of coating by dust deposition in kiln riser ducts, meal pipes, ducts and cyclones due to excessive contents of chlorine in the kiln system,” A TEC said in a press release.

“A TEC’s REDUCHLOR bypass consists basically of a take-off chamber above the kiln inlet, specifically designed for each installation and a specially designed quenching chamber where the chlorine condensates on and adheres to the fine dust particles. After this condensation process the chlorine-enriched material is collected in a filter.”

The project will be commissioned in 2017. A TEC is a member of the Loesche family of companies. The company specialises in the increasing the efficiency of cement plants, completing more than 450 optimisation projects in the industry.
