The course will explain the basic chemistry of radical combustion (oxidation) reactions. The examples documented impact of conditions (temperature, pressure, concentration) on the intensity and speed of combustion reaction and the formation of various intermediates and products, including disabled harmful substances. By means of practical calculations, students are introduced to the basic mass balance combustion reactions.
Aim of the course -

Students will be able to:

Explain the basic chemism of radical combustion reactions.

Explain the basic physico-chemical aspects influencing the process of combustion of gaseous, liquid and solid substances.

Explain the basic principles of generation of pollutants resulting from the combustion process (NOx, SOx, PM).

Apply the basic mass balance of combustion processes.
