combustion technology

Development, inspection and optimisation

You want to find out how to improve boiler efficiency? Or you would like to replace the furnace or the refractory lining? Or maybe you want to use new fuels such as wood?

Flow simulations can be used to compute widely differing scenarios of combustion, fuel combinations and geometries.

We can help you to check the feasibility of such ideas and to minimize your project risk! Depending on the brief given we will support and consult you, making use of selected models and our network of contacts and, not to forget, our wide range of practical experience.


The most different fire systems can be examined:

  • Gas firing installations
  • Melting chambers (gas, metal) and their firing systems
  • Duct burners
  • Lean gas burners
  • Oil firing installations
  • Coal firing installations
  • Grate firing (RDF, waste, coal, wood)
  • Incinerating particular substances
  • GT-waste heat boilers
  • Kilns (ceramics)
hard-coal flame;
Calculating grate-combustion for coal, oil, gas and RDF using commercially available and internally developed models.
hard-coal flame; Calculating grate-combustion for coal, oil, gas and RDF using commercially available and internally developed models.

The computations can be used to investigate the following situations:

  • Flame development, e.g. the twist direction of burners
  • Burner inlet flow and pressure loss of airing system
  • Layout of over-fire airing and wall vents
  • Forecast for wall atmospheres and CO and O2 distribution
  • FG temperature at end of fire chamber
  • Temperature development in fire chamber
  • Flue gas residence times
  • Heat flow density at membrane wall
  • Heat flow density at refractory lining
  • Selection of burner types
  • Qualitative emission forecasts for NOx, CO, CO2, O2
