Computational Fluid Dynamics (CFD) Modeling


  • Chemical Recovery Boilers
  • Biomass Boilers
  • Waste-to-Energy Boilers (MSW & RDF)

JANSEN uses Computational Fluid Dynamics (CFD) modeling software to analyze fluid flow patterns, fuel combustion processes, fuel capacity, emissions performance, and heat transfer profiles in various boiler-related equipment. The scope of services typically includes boiler data collection, set-up of a model to evaluate current performance, and the use of this model to evaluate conceptual improvements. CFD modeling by JANSEN is conducted in-house by JANSEN engineers.

Computational Fluid Dynamics Applications

Typical areas where JANSEN applies Computational Fluid Dynamics (CFD) modeling to predict, evaluate, and/or optimize performance of boiler equipment include:

  • Modifications to the combustion air delivery system.
  • Evaluation of temperature and oxygen distribution in combustion furnaces.
  • Optimization of the liquor distribution in recovery boilers.
  • Heat transfer analysis in superheaters, generating banks, and economizers.
  • Analysis of flow pattern and particulate distribution in inlet ducting to precipitators.
  • Evaluation of combustion conditions in waste fuel- and fossil fuel-fired boilers.
  • Evaluation of boiler emissions performance (TRS, CO, VOC, SO2, NOx, particulates).
  • Spray cooler, scrubber, and cascade/cyclone evaporator performance predictions.
  • Evaluation of HVLC and LVHC NCG incineration.
