Keeping kilns cool

Published 12 September 2016

Kiln hotspots are one of the causes of mechanical stresses on cement kilns. However, this issue can be addressed with the use of a water- or air-based kiln cooling system. One Germany-based firm makes the case for water-based systems. By Alexander Scholl and Dirk Schmidt, Kima Echtzeitsysteme GmbH, Germany.

A water-based kiln cooling system provides additional benefits to air-based equipment

Increasing demands in terms of energy consumption, productivity, emissions and operational costs require cement producers to consider different enhancements to their production facilities. Processes need to be redefined and adapted, machines have to be upgraded and optimised, used technologies have to be evaluated and assessed, and employees need to be trained and involved. In kilns these developments are particularly reflected in higher daily production rates (many kilns are now operating at ≤10,000tpd) and an increased usage of alternative fuels.
