FSI-IETAcad. year: 2020/2021
The course is focused on the effects of energy transformations on the environment, especially on air. Students are acquainted with pollutants released or generated during combustion processes, greenhouse gases and climate change, mechanisms of pollutant spreading in the atmosphere and their impact on the environment. The course also includes basic information from the technology of dedusting, flue gas desulfurization and reduction of nitrogen oxides in flue gases (primary and secondary measures). The conclusion is devoted to the issue of recovery and disposal of products / residues of purification technologies (waste water, gypsum, fly ash).
Learning outcomes of the course unit
The knowledge gained in the course will enable the student to orientate in the design of technological equipment to reduce the negative impacts of combustion on the environment, qualified management of the operation of small and large industrial power units.
Knowledge of thermomechanics, energy boilers, fuel combustion and basic knowledge of atmosphere physics.
