Argomenc dl curs
The Power Production, CHP and District Heating Systems course is a core teaching in the context of the Master in Energy Engineering and, specifically, it deals with the industrial plants used for electric and thermal power production both for small scale and community scale appliances. The course consists of two modules. The first module starts with the description of the main energy resources with a particular focus on renewable sources. Then, fundamentals of energy conversion are presented, along with the working principles and the main operational aspects of the most used cogeneration plants both for large scale and for small scale distributed generation. Thermochemical processes are analyzed by means of thermodynamic and kinetic approaches, as well as direct conversion technologies. Technical aspects of power generation systems and solutions to improve their energy and environmental performance are presented, dealing also with constructive aspects, plant operation and management issues and heat distribution networks. The second module introduces the fundamental concepts of cogeneration and presents the most used cogeneration solutions for civil and industrial applications. The working principles of the core devices of power production plants are presented. The main mechanical, fluid-dynamic and energy conservation principles and equations will be described and applied to the presented components of the power production plant. In particular, the following educational objectives will be addressed: constructive aspects, behavior of the fluid machines employed in power production plants, components, thermo-fluid-dynamic laws, evaluation of the plant performance in design and off-design operating conditions.

The student is asked to produce a project work on the design of an energy system (also integrating the topics of the other module of the course); this part of the assessment evaluates the ability of the student to apply the topics of the course in practical applications, the comprehension of the theoretical concepts and the ability to make judgments. The student is also asked to carry out an oral exam for each module of the course. The oral examination includes questions to assess the knowledge and understanding of the course topics and questions designed to assess the ability to transfer these skills to case studies of energy plants and thermal and electric energy production devices.

Criters de valutazion
Assessment language: English Students regularly enrolled in the 2nd year of the Master in Energy Engineering are eligible for the attendance of the lessons and the exam. Other exceptional cases have to be discussed with the Professor. Oral exam 鈥� theory (open-end questions): The oral exam on the theory assesses the knowledge and understanding of the course topics, the knowledge of the fundamentals of conversion technologies, of the operating principle and the design choices of energy production plants for community scale and small-scale cogeneration, as well as the ability to transfer these skills to case studies and to make judgment. The following criteria will be considered: - Correctness of the design choices - Correctness of the dimensioning procedure - Correctness of the numerical solution - Appropriate use of measurement units - Theoretical knowledge - Ability to provide examples/applications of the theoretical concepts Project work presentation: The following criteria will be taken into account: - Theoretical knowledge - Ability to provide examples/applications of the theoretical concepts - Communication skills and master of the technical language The final mark will be weighted as follows: oral exam (70%, equally weighted for each module), project work presentation (30%). It will not be possible to pass the exam if the oral exam of both the modules has not been positively evaluated.

Depl霉 informazions
Connections with other courses: The courses 鈥淎pplied Energetics鈥� and 鈥淔luid Machines Engineering鈥�, offered in the first semester, supply the main concepts of Engineering Thermodynamics and Fluid Machines. These topics are deepened in the Power Production, CHP and District Heating Systems course and specific and practical applications of power conversion systems are presented. The know-how acquired in the present course will be useful to follow the curricular courses 鈥淒istrict Heating System Design鈥� and 鈥淏ioenergy鈥� and the elective course 鈥淓lectric and hybrid mobility鈥�. Professional applications of the covered topics: The knowledge acquired through the first module (Thermal Power Production and Distribution) can be applied in the design and management of thermal plants and industrial energy systems. The related professional tasks are relevant to traditional and innovative technologies for thermal power generation, e.g. combustion, gasification and pyrolysis. The competences can be deployed in private engineering companies, in public agencies, in utilities companies, as well as in the industry. The contents of the second module (Thermal engines ) will be useful for all the professional tasks, in the industry or in the public sector, related to the use of power plants and fluid machines in the energy conversion process. Typical jobs can be related to the design of cogeneration systems, boilers, fluid machines for power conversion (steam and gas turbines, combustion engines), management and control of power plants. These competences are necessary in the companies designing, managing and maintaining power plants, in utilities鈥� companies and in the industries designing components and solutions for the power conversion.
