Impianti di Conversione Energetica
Energy conversion plants Gabriele Comodi
Rankine and Brayton thermodynamic cycles; knowledge on main turbomachineries (pumps, compressor, hydraulic turbines, gas and steam turbines); steam generators; heat transfer.
KNOWLEDGE AND UNDERSTANDING:
The aim of this course is to provide students with advanced knowledge on energy conversion plants. The course completes the previous engineering education deepening the understanding of energy conversion systems in both industrial and energy fields. In particular, students increase their knowledge on the issues related to the systems involved in the production and conversion of energy also taking into account the different sources and their energy markets. The study of energy conversion systems under a technical and economic point of view provide the students with the awareness of the multidisciplinary context of the mechanical engineeringCAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
Students enhance their ability to assess both the main parameters affecting the design of energy conversion systems (both renewable and fossil) and their techno-economic-environmental impact. The main skills acquired in the course are: 1. Ability to assess, under technical/economic/ environmental point of view, the potentialities and limits of energy conversion systems; 2. Ability to choose the suitable energy conversion plant in order to reduce costs, energy consumption and environmental impact; 3. Ability to pinpoint the criticalities related to the external context of energy systems such as legislation and energy markets; 4. Ability to communicate with proper, high level, engineering terminologyTRANSVERSAL SKILLS:
The deepen knowledge of energy conversion systems will improve the judgement autonomy of students and their communications skills with particular regard to the use of a proper, high level, engineering terminology. The study of energy conversion systems under a technical and economic point of view provide the students with the awareness of the multidisciplinary context of the mechanical engineering so that they will be able to communicate and cooperate in different context both with engineers and non-engineers
Introduction to the global energy question; the Italian energy system (gas and electricity); big power plants (nuclear, gasification of coal, natural gas); IGCC, combined cycles and repowering of steam plants; distributed generation, cogeneration, absorption chillers and trigeneration, smart grid, energy storage; the energy markets and tariffs: electricity, natural gas; green certificats, feed-in tariff, white certificates, Emission Trading System; role of both Energy Service Companies (ESCOs) and energy manager in the industry and tertiary sector.
Development of the examination
LEARNING EVALUATION METHODS
The final exam consists in a written examination. Students must answer to several (usually 12) questions. Student could have the opportunity of taking a preliminary examination in order to get the final examination vote. Disabled persons with difficulties in writing or foreign students can take an oral examination.
LEARNING EVALUATION CRITERIA
Following criteria are used for the evaluation of the answers: 1) relevance with the question; 2) completeness; 3) correct use of engineering terminology; 4) clearness
LEARNING MEASUREMENT CRITERIA
Each answer will be evaluated with a vote ranging between 0-30
FINAL MARK ALLOCATION CRITERIA
The final vote will be calculated as the average of the votes of all the questions (both answered or not). To pass the exam, the average of votes must be equal or higher than 18/30.
