Learning outcomes of the course unit
This course provides students with the necessary knowledge for operating energetic units and environmental technologies. The acquired knowledge enables students to design and project dust eliminating and desulphurisation devices for middle and small-sized energetic units.
Prerequisites
Thermo mechanic basics, sources and transformation of energy.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
Course-unit credit requirements:
- Attendance at seminars
- handing in notes from seminar calculations
- working out an assignment
Aims
The course objective is to make students familiar with basic environmental technologies so that they will be able to judge basic trends in the clean energy production.
Specification of controlled education, way of implementation and compensation for absences
Attendance at seminars is required, compensation of missed lessons to be negotiated with a teacher.
