Forschungsergebnisse: Einfluss der Verringerung von Schmelzpunkt und Viskosität der Klinkerschmelze durch Aschen alternativer Brennstoffe auf Sinterreaktionen und Coatingbildung

Available in German

Ziel des Forschungsvorhabens war es, den Einfluss von Nebenoxiden aus Brennstoffaschen auf die Bildungstemperaturen der Klinkerschmelze und auf die damit verbundene Klinkermineralogie herauszuarbeiten. Ebenso sollten die Auswirkungen der verringerten Prozesstemperatur und der veränderten Eigenschaften der Klinkerschmelze auf die notwendige Bildung von Coatingschichten sowie die Feuerfestkorrosion und damit auf die Haltbarkeit der feuerfesten Zustellung in der Sinterzone des Drehrohrofens aufgeklärt werden.

Research projects


Current

Durability of concretes with clinker efficient cements under modified concrete technological conditions

The current research project aims to determine if CEM II/C-cements can be used in some exposure classes (XC1-4, XF1) according to DIN 1045 2 under modified technological conditions of the concrete (reduced water-cement ratio, increased minimum strength class) without additional requirements.

Current

Raw meal screening: Energy-optimised fine-rod screening of raw cement meal for the evaluation of process-relevant characteristic values

The subject of the research project is the fine-tuning of dry cement raw materials. The focus is on the influence on the electrical energy requirement during the comminution of the raw material and the thermal effects on the subsequent clinker burning process, caused by a changed raw meal granulometry.

Online Course

Firing Alternative Fuels: Opportunities, impacts on process, optimisation and limitations (Training course 1)

VDZ offers an online course that covers all the relevant aspects concerning the use of alternative fuels in cement plants. Starting with the main political drivers such as the circular economy and the European waste fuel strategy, the training will give a detailed view of the current state-of-the-art-situation with regard to the use of alternative fuels in the EU. In this context, pre-treatment and suitable quality control of alternative fuels will be also explained and presented. A main focus will be given to the drivers and barriers of the use of alternative fuels within the burning process. Relevant aspects will be explained and discussed with the participants. Finally, technical feasibilities, case studies and possible optimisation potential will be part of the training course. This training course provides four half-day training sessions in a webinar format. This unique format enables the employees to combine an adequate learning pace with their daily work in the plant.

Congress

International­ VDZ Congress 2018

Climate protection and digitisation are key challenges for the cement industry: More than 600 representatives from the international cement industry and associated suppliers, as well as from scientific and research institutes around the world, gathered at the International VDZ Congress 2018 in Duesseldorf at the end of September. Steeped in tradition, the VDZ Congress is one of the world's most important events in the industry. The 40 talks held at this year's congress focused on particularly pressing topics such as climate protection and digitisation. The participants also discussed current technical challenges and the general situation with regard to cement production. A further highlight was an evening ceremony at which the winners of the VDZ Industrial Safety Prize 2017 received their awards.
