Course detail

Conversion of Energy and Its Impact on Environment

FSI-LVPAcad. year: 2011/2012

The course is concerned with power engineering and its influence on the environment, above all, on the air. Student will be made familiar with pollutants from the combustion process, and they will learn of flue gas cleaning (dust eliminating, desulfurization and technologies reducing NOx emissions. Last lecture deals with the dumping of solid residues from cleaning technologies.
