Course detail
Designing of Thermal Power Plant Equipment
FSI-FSE Acad. year: 2021/2022 Winter semester
The course is focused on two areas of energy. The first area contains heat exchangers, ie the applied issue of heat sharing. Students will learn about the types of heat exchangers, operational problems and the basic design of tubular exchangers. The second area includes the use of fuels (biomass, waste, coal, natural gas) to generate heat and power. Students will go through the energy equipment from the fuel, through the combustion chamber to the steam part of the boiler and get acquainted with the specifics of individual fuels.

Learning outcomes of the course unit
Student will get theoretical knowledge about design of boiler, heat exchanger and about operation condition of components of these devices. They will be also made familiar with methods of increasing reliability and efficiency together with impacts on the environment.
Prerequisites
Basics of thermo mechanics and heat transfer.
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. An excursion is planned within the course.
Assesment methods and criteria linked to learning outcomes
Exam – written, verbal correction, if any – are eligible for the oral test is obtained accreditation
Credits – award conditions: participation and active work on the exercises, a written test.
Aims
The aim of the course is to offer students an insight into the issues of thermal energy and to acquaint them with the basic applications of heat transfer and combustion.
Specification of controlled education, way of implementation and compensation for absences
Attendance at lectures is not compulsory, but is recommended. Attendance at seminars is required (At least 75%), compensation of a missed seminar by studying literature.
