Energy-Saving Measures and Modifications to the Electric Control System of Existing Kiln and Dryer Installations

The thermal processes in kilns and dryers are essential factors in the operation of a production plant. In the manufacture of ceramics, the product quality as well as energy consumption are strongly dependent on the design of the process systems. The considerate management of resources, sustainability and the reduction of CO2 emissions are significant features resulting in lowered and optimized cost of operation on the one hand and, at the same time, in a contribution to environmental protection.
