Participants learn about the newest calciner designs with a focus on gasification and pre-combustion of alternative fuels.

Process engineers, plant design engineers with experience in process engineering in cement manufacturing, combustion experts

Virtually all new kiln installations in the cement industry designed worldwide today are equipped with precalcining technology. Precalciners provide particular flexibility, as NOₓ and CO emissions are influenced by calciner operation, and alternative fuels can be fed at several firing places at different temperature levels. In addition to economic criteria, physical criteria (e.g. particle size) and chemical criteria (e.g. chlorine, sulphur, alkali and phosphate content) play a decisive role in the selection of alternative fuels as they can have an impact on the kiln operation and emissions. The seminar will give an overview of the current state-of-the-art of calciner designs, the use of alternative fuels, and the possibilities of controlling NOₓ and CO emissions by fuel, air or meal staging. Current state of the art thermal pre-treatment systems for the burning or gasification of alternative fuels will also be presented.

• Kiln operation with high-level use of alternative fuels in the calciner
• NOx reduction and burnout optimisation in the calciner (VDZ)
• Different concepts for the pre-combustion or gasification of alternative fuels, e.g.
  • Hot Disk
  • Circulating fluidized bed
  • Step Combustor
  • Hot burning chamber
  • Pyrorotor
  • Fire Bed Combustor
  • FUELFLEX® Pyrolyzer
