This course aims to provide knowledge about energy systems in the industry, and the energy efficiency of their processes. Students will be introduced to energy consumption in the industry, industrial policy in the EU and the Republic of Croatia, and recommendations and barriers for improving the energy efficiency in the industry. An overview of industrial processes and analysis of the industrial energy systems and their energy demands are given. The course provides knowledge on the connection between energy utilisation and industrial generation, but also the impact of industrial energy systems on the environment.

Student responsibilities:

Attending classes and participating in assignments. Making homeworks. Preparations of homeworks and seminars. Applying computer tools.

Grading and evaluation of student work over the course of instruction and at a final exam:

Continuous work through the semester by making homeworks.

Upon successful completion of the course, students will be able to (learning outcomes):

1 . Analyse energy consumption in the industry;

2 . Identify the primary energy flows in the industry;

3 . Analyse energy systems in the industry;

4 . Assess the quality of energy systems in industry in terms of energy efficiency and reduction of environmental impact;

5 . Analyse and recommend energy efficiency measures in the industry;

6 . Analyse integration of renewable energy sources into the industry;

7 . Assess the integration impact of renewable energy sources in the industry on current and future energy systems in the industry;

8 . Apply computer tools to calculate fuel combustion, boiler and industrial furnace efficiency, and maximum heat recovery;

9 . Utilize open databases to collect and process data related to energy systems in the industry.
