Revised Application technology rotary kiln in the Glass & Minerals sector

Rotary kiln

Increasing production or TSR with oxygen


Oxygen increases the quality of the combustion locally, which means that the replacement fuel rate can be further increased.



  • Optimisation of energy costs through cheap, low caloric secondary fuels 
  • Higher adiabatic flame temperature
  • Faster reaction speed 
  • Fossil fuels replaced by waste materials 
  • More rapid ignition of low caloric fuel particles makes total combustion possible before reaching the clinker bed
  • Use of replacement fuels with even lower heating temperatures (solid and liquid) 
  • Replacement of compressed air for atomisation
  • Additional parameters for kiln control (fast and easy to control)
  • Stabilisation of kiln operation  
  • Reduction in CO2 Certificate
  • CO2 Certificate for O2 production is Messer’s responsibility   
  • Greater gas radiation
  • Constant NOx through adjusted oxygen input
  • Less strain on the induced draft
  • Increase in production also possible 


In addition to the gases required for your process, Messer offers a variety of equipment for its optimisation under the brand names Oxipyr and Oxijet. 

In order to select the optimum system, experts from Messer first carry out a comprehensive process analysis. Following calculations and basic engineering, suggestions are made for optimisation and further procedures.
