In October last year the RTO plant went into operation. The abbreviation of the post-combustion plant, RTO, stands for the principle of Regenerative Thermal Oxidation. In this case, regenerative means that the exhaust gas is heated up and cooled by means of high energy efficiency through large ceramic heat accumulators in the towers of the plant. In the combustion chamber, which is mounted on the five towers of the plant, the exhaust gases stay at 850 degrees Celsius for at least two seconds, which over 90% of the organic air pollutants (TOC) are destroyed.

“Combined with the mercury reduction plant and the dust filter plant upstream of RTO, the post-combustion plant sets new standards in terms of emission control systems in the cement industry,” noted Florian Salzer, operations manager of the cement plant.

Facts & Figures of the RTO:
The first parts of the post-combustion plant were delivered at the beginning of 2017, and their construction started in March 2017. A total of almost 1,400 tons of material were processed by around 250 employees during 25,000 working hours. The post-combustion plant consists of 52,000 ceramic regenerator bricks with a total surface area of 300,000 square meters
