Aim
The aim of the course is to introduce the students to the equipment implementing the thermodynamic cycles and the real processes taking place in them. The basic knowledge of combustion technology required to understand these is also passed on, so that some of the problems in everyday life can be easily understood (eg fire for grilling, operation of a domestic boiler, air conditioning, heat pump heating, operation of internal combustion engines, air pollution).
Learning outcomes
Competences that can be acquired by completing the course
Knowledge
Knows and uses the basic concepts of firing technology in practice. The students understand and uses knowledge of combustion theory in environmental protection. The student knows the processes that take place in domestic and industrial boilers. The student interprets the structure of the special steam turbine, the way of energy conversion. The student knows the structure of the reaction steam turbine, the way of energy conversion. The student understands the design of a gas turbine for energy purposes, the role of his turbine, compressor and firebox. The student is aware of the main features of the construction of a gas turbine used in aviation. The student informed about the operation of the compressor refrigerator. The student understands the structure of the compression and spark ignition engine, the processes that take place in them. The student is aware of the possibilities of increasing the performance of internal combustion engines, their advantages and disadvantages.
Ability
The student is able to identify combustion processes in real equipment. The student is able to describe real systems with abstract thermodynamic models. The student distinguishes between solutions for different abatement methods. The student is able to represent thermodynamic processes in state diagrams. The student applies to solve more complex thermodynamic problems in real equipment. The student distinguishes between the operating, control and design solutions of different mixing systems. Apply his knowledge of thermodynamics, recognize deviations from theoretical processes. The student selects the type of chiller to suit your needs. The student describes the control methods of steam turbines and their design elements. The student describes the cycle losses of an internal combustion engine (Diesel, Otto, Wankel).
Attitude
The student constantly monitors his work, results and conclusions. The student seeks to routinely use equations that describe state changes in equipment. The student is constantly expanding his knowledge in the field of thermal power plants. The student is open to the use of information technology tools. The student seeks to learn about and routinely use the tools needed to solve problems with calorie machines. The student is susceptible to changes in science, economic and social systems. The student seeks to apply the principles of energy efficiency and environmental awareness in solving tasks related to energy machines.
Independence and responsibility
The student independently thinks through thermodynamic problems and problems and solves them based on specific resources. You will make a confident and informed decision using your extensive knowledge. In some situations, as part of a team, you work with your fellow students to solve tasks. With his/her knowledge, the student makes a responsible, informed decision based on his/her analyzes. The student feels responsible for the sustainable use of the environment and for present and future generations.
Teaching methodology
During the teaching of the subject, the lecture and practice are separated, both in terms of content and methodology. The lectures basically introduce students to the information defined by the knowledge competence elements using the technique of frontal education. The lectures in printed form and in the written study materials available online are complementary and are not sufficient to achieve adequate preparation. The practical sessions promote the application and skill-based acquisition of knowledge with a thematic theme. During the exercises, the knowledge previously acquired at home and independently is solved partly jointly and partly individually with the help of the practice leader.

General rules
There is only one faculty performance evaluation during the semester, at week 14. If the exam is successful (a sufficiently sufficient grade), the writing of the exam can be omitted, only the exam opportunity announced for the recommended fiancées should be taken. Learning outcomes are assessed on the basis of an optional summary written assessment. This is a complex, written way of evaluating the competence-type competence elements of the subject and knowledge in the form of a dissertation, the dissertation focuses on the application of the acquired knowledge, ie practical tasks must be solved, The oral performance evaluation of the exam is a complex, oral way of evaluating the competence-type competence elements of the subject and knowledge, it basically focuses on the application of the acquired knowledge, simple theoretical and practical (calculation) tasks must be solved. Preparation time 10 minutes.
Assessment methods

| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | The complex, oral way of evaluating the competence-type competence elements of the subject and knowledge, basically focuses on the application of the acquired knowledge, ie simple theoretical and practical (calculation) tasks must be solved during the performance appraisal. the available preparation time is 10 minutes. | |
The weight of mid-term assessments in signing or in final grading
The subject does not include assessment performed during the semester period.
The weight of partial exams in grade
| Type: | Proportion |

| Oral partial exam | 100 % |
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |
| very good (5) | Very Good [B] | 85 % - 90 % |
| good (4) | Good [C] | 72 % - 85 % |
| satisfactory (3) | Satisfactory [D] | 65 % - 72 % |
| sufficient (2) | Pass [E] | 50 % - 65 % |
| insufficient (1) | Fail [F] | below 50 % |
The lower limit specified for each grade already belongs to that grade.
Attendance and participation requirements
The lack of the value means that there is no attendance requirement.
At least 70% the exercises (rounded down) must be actively attended.
Special rules for improving, retaken and replacement
The special rules for improving, retaken and replacement shall be interpreted and applied in conjunction with the general rules of the CoS (TVSZ).
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
