Denmark: Aalborg Portland has awarded A Tec a contract to upgrade its Cement Kiln 87 in Aalborg. It has ordered two calciners for its 4500t/day semi-dry kiln system that was commissioned in 1988. The calciners will be designed and delivered during the kiln’s annual stop in February and March 2017. Commissioning is planned for the spring of 2017. The upgrades are intended to increase production of Ordinary Portland Cement on the line.

A Tec intends to adapt the flow pattern of the calciner system in a way to improve the operational behaviour of the system. The design will be configured for the usage of 100% solid alternative fuels with low emissions. Additionally, the number of kiln stops due fall through cyclone blockages should be reduced. A Tec will conduct the engineering, supply the equipment and will be responsible for errection and documentation.

The new calciner system will be equipped with the A Tec Post Combustion Chamber (PCC) for the optimised mixture of fuels and combustion air in the end section of the calciner. The PCC was specially developed for the achievement of complete combustion of alternative fuels at high substitution rates.
