Research topic
Research title: Pyrolysis oil combustion in gas turbines.


Combustion of pyrolysis oil in gas turbines is a way to generate heat and electricity from a biomass feedstock.

In the pyrolysis process, typically 60-75 wt% of the biomass is converted into bio-oil that can be used as an alternative to fossil fuels. However, the chemical and physical properties of pyrolysis oil differ significantly from those of diesel oils or other common gas turbine fuels. High viscosity, delayed ignition time, low heating value, corrosion effect and solid content make pyrolysis oil a challenging fuel for utilization in modern gas turbines.

Modification of certain parts of the gas turbine is necessary in order to reduce the negative effects of these properties to acceptable levels. The main goal of the research is to identify and resolve the problems that arise when pure or blended pyrolysis oil is used to fire an industrial gas turbine.

Field tests on a combustion chamber and experimental research in the laboratory will be carried out to improve the atomization and combustion efficiency of pyrolysis oil. In addition, numerical modeling (CFD) will be used to support and validate the experimental work and for upscaling the results.
