Course detail

Combustion and Fuels

FSI-9PASAcad. year: 2020/2021

Course consist from two main parts. The first part deal with fosil fuels, alternativ fuels (biomass, wastes) fuel composition properties and it's effect on combustion. The second part deail with combustion process, physical chemistry, combustion thermodynamic, chemical equilibrium gas mixture, turbulence and production of NOx, SOx emissions.

Learning outcomes of the course unit

The student will acquire knowledge about fuels and the influence of individual properties on the combustion process, emissions of undesirable substances and design of combustion plants. The graduate will gain a deeper insight into the kinetics of combustion reactions and possibilities of influencing the combustion process.
