Course detail

Conversion of Energy and Its Impact on Environment

FSI-LVPAcad. year: 2018/2019

The course is focused on impacts of power engineering and its influence on the environment, above all, on the Air Quality, air pollution meteorology and dispersion of a polutants. Students will be made familiar with harmfull pollutants from combustion process, and they will learn of flue gas cleaning (gas filter, impingement separator, electrostatic presipitatorts), desulfurization process and technologies reducing NOx emissions(primary andsecondary measurments).
Last lecture deals with the dumping of solid residues from cleaning technologies.

Learning outcomes of the course unit

Students will learn of basic stoichiometric calculation of combustion processes, calculation of reactant consumption. They will acquire the basic knowledge of flue gas cleaning technologies and knowledge for designing individual devices used for flue gas cleaning.

Prerequisites

Boilers, sources and transformation of energy, termomechanics.
