Learning objectives
Knowledge
- 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
Skills
- 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
Competences
- 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
Type of instruction
Lectures in combination with tutorials, assignments,
hands-on, and e-learning activities.
