D1 - Knowledge and understanding. The course aims at providing the knowledge to assess the technologies used in the energy transformation processes. In particular, power plants are considered in all the operation mode (generation, cogeneration and trigeneration). D2 - Applying knowledge and understanding. Applying knowledge, understanding and skills in solving problems in new areas included in wider contexts related to the energy analysis of industrial processes. D3 - Making judgements. Develop the ability to complete knowledge and manage complexity. Ability to make judgment on the basis of limited/incomplete information including the analysis of the ethical and social responsibility. D4 - Communication skills. Develop the ability to communicate clearly the knowledge to specialist and non-specialist interlocutors. D5 - Learning skills. Develop learning skills that allow to continue the study autonomously.

Fundamentals of Engineering Thermodynamics (Fisica tecnica) and Power Plants (Macchine) are suggested.

Lectures supported by the use of a computer and a projector. During the semester are scheduled at least two technical visits to power plants.

Additional teaching material will be available for students on the Moodle platform.

Aim of the exam is to assess an adequate knowledge of the theoretical and practical topics discussed in the course and the ability to apply them to the solution of basic engineering issues regarding power plants and energy flows analysis in industrial plants. The exam consists of an oral examination, articulated in three extended questions. Grades are from 1 to 30. Minimum grade: 18.
