The aim of the course is to acquire principles of heat source choice, water and steam boilers' efficiency parameters and those increasing possibilities. The heat balance of boiler equipment and the influence of separate positions to efficiency are analysed. Students obtain the principles of efficiency increasing in heat production, distribution and utilization.
1. Knowledge - knows the factors influencing the efficiency of heat production and heat energy consumer equipment and systems, the possibilities to increase it – report.
2. Skills - is able to perform heat production and consumption equipment and systems, heat transfer systems, heat utilization criteria assessment, perform efficiency improvement analysis - report.
3. Competence - evaluation of energy flow in heat production, distribution, use, in application of efficiency improvement solutions - test.
1. Energy balance of heat production boiler equipment (Lecture 1h, Practical works 2h)
2. Choice of topic in the report, drawing up a plan (Lecture 1h, Practical works 2 h)
3. Parameters for determining the efficiency of heating equipment operation, their measurement (Lecture 1h)
4. Improvement of factors influencing the efficiency of heat production equipment (Lecture 1h)
5. Substantiation of engineering calculations of the report, choice of methodology, individual application to the topic (Lecture 1h, Practical works 4h)
6. Technical and economic evaluation of primary energy resources, its selection (Lecture 1h)
7. Losses in heat transmission and distribution, their reduction (Lecture 1h)
8. Presentation of the middle stage of the report (Practical works 3h)
9. Conditions for efficient energy use of a heat energy consumer (Lecture 1h)
10. Report presentation creation, conditions and rules (Practical works 1h)
11. Possibilities of heat energy storage, heat accumulation Practical works 3h)
12. Presentation of the report (Practical works 2h)
A report must be submitted and presented. Assessment - test
Independently writes a report, makes the necessary calculations.
The assessment is influenced by: the volume, content and quality of the report, the quality of the presentation, attendance of classes
