Biomass Gasification, Combustion and their Advanced Modelling


Content, progress and pedagogy of the module

The module adds to the knowledge obtained in Heat transfer; Fundamentals of CFD; Combustion theory; Fluid mechanics.

Learning objectives


  • Understand solid biomass feedstock: Fuel characterisation, representative biomass thermochemical conversion technologies, heat/mass transfer and various reactions in biomass thermochemical conversion
  • Understand radiation heat transfer without or with participating medium: Surface-to-Surface model (extended network method) for radiation heat transfer without participating medium; radiative transfer equation, radiative properties of participating medium, and various models for radiation heat transfer with participating medium
  • Have knowledge about biomass gasification and combustion on different scales such as particle, reactor and plant levels
  • Have knowledge about biomass gasification technology for green fuel production: Principles, key factors, types of gasifiers and their key characteristics, gasifier design, green syngas or producer gas, success stories of biomass gasification
  • Have knowledge about representative biomass combustion technologies for renewable heat and power generation such as grate-firing and suspension-firing: Different arrangements/layouts, special components, key topics, overall modelling strategy and special sub-modelling issues


  • Be able to identify the appropriate utilisation technology for a given biomass based on its properties
  • Understand thermal radiation heat transfer, various applications, and advanced modelling of radiation heat transfer without and with participating medium
  • Understand the mechanisms and the key issues in biomass gasification and the modelling
  • Understand the key sub-processes in biomass combustion and various key biomass combustion technologies (their advantages and disadvantages, and modelling strategies)
  • Be able to develop key sub-models for biomass conversion and implementing them into commercial CFD


  • Have in-depth understanding of all the important issues in biomass gasification and combustion, including combustion physics (e.g., radiative heat transfer, turbulent flow) and combustion chemistry (e.g., pyrolysis, homogeneous and heterogeneous reactions)
  • Be able to develop sub-models and codes for the key, special processes in biomass gasification and combustion process and ability to perform a reliable CFD of biomass gasifier and combustor
