HeidelbergCement making savings with new compressed air supply
At HeidelbergCement AG’s plant in Triefenstein-Lengfurt, around 400 t fuels are used daily in the rotary kiln. It is therefore important to exploit all saving potential, not only in the process engineering. A new efficiency level has now been achieved with the modernization of the compressed air supply with four new GA-screw compressors from Atlas Copco. As a result, HeidelbergCement is saving 150 000 kWh in electricity per annum.
For its daily production of 3000 t clinker, the rotary kiln measuring 78 m in length and 5.2 m in diameter needs around 400 t fuel per day.
In view of such a huge amount of energy, isn’t the efficiency of the compressed air station negligible? “No way,” explains Dominik Azadi, Head of Maintenance and responsible for the energy management system at Lengfurt cement plant owned by HeidelbergCement AG. “Naturally, the fuels as energy sources account for the largest part of our energy consumption. This, however, is necessitated by the process. For this reason, we, naturally, look at other areas for...
