Programma dettagliato e risultati di apprendimento attesi

Main objectives and contents of the course

The course aims at two basic objectives:

1)         review relevant basic principles and tools for the analysis of energy conversion systems

2)         develop the capability to analyze, model and assess the performance of conventional as well as advanced systems for the production of electricity, heat, and refrigeration power

Among the energy conversion technologies, particular emphasis will be given to steam cycles, gas turbines and combined cycles, since they account for essentially all the electricity now generated by central power stations and are likely to maintain such role in the future.


Description of topics covered by the course

Energy scenario: seminar giving an overview of world energy demand, production, expected evolution.

Fuels and combustions: Basic properties of fossil fuels, stoichiometry and energy balance of combustion reactions, evaluation of parameters relevant for the assessment of the performance of fossil fuel-fired energy systems.

Pollutant formation and abatement: Kinetics of pollutant formation in combustion processes (CO, NOx, HC, PM). Basic principles of primary and secondary abatement technologies for steam cycles and gas turbines.

Steam Cycles: Basic thermodynamic features and configuration. Regeneration and reheat. Optimization of operating parameters. Interaction between cycle parameters, scale and turbo-machine performance. Architecture and basic issues of steam generators. Material issues. Modern Ultra-Super-Critical plants.

1st and 2nd Law analysis: Energy balances of energy conversion systems. Fundamentals of 2nd Law analysis. Applications to the basic processes encountered in energy conversion systems. Reactive systems and combustion.

Gas turbines and combined cycles: Basic thermodynamic features and configuration of Joule cycles. Regeneration, intercooling and reheat. Choice of cycle parameters vs type of duty and application. Material issues and blade cooling. Motivation and basic features of combined cycle configuration. Heat Recovery Steam Generators.

Economic analysis: Basic approach and tools to evaluate the cost of electricity. Comparative analysis of most relevant fossil fuel-based and renewable-source-based power plants.

Heat exchangers & steam generators: Architecture, basic features and issues of the heat exchangers utilized in large energy conversion systems. Case study on heat rejection by a large power plant.

Cogeneration: Meaning and motivation of cogeneration. Applications to steam cycles, gas turbine and combined cycles, internal combustion engines. District heating applications. Performance indexes.

Refrigeration cycles and heat pumps: Inverse thermodynamic cycles. Choice of working fluids and configuration. Multi-level arrangement.

Note Sulla Modalità di valutazione

The exam consists of a written examination divided into two parts. The first part consists of two numerical problems, the second part of two open, theoretical questions. Consulting books or lecture notes is allowed for the first part (numerical problems) but not for the second. One of the two theoretical questions will refer to the topics covered in the precepts,

The solutions of the numerical problems and the answers to the theoretical questions must be exclusively in English, in clear and ordered handwriting. Solutions or answers not in English will not be graded. Likewise for solutions and answers which do not show and explain clearly, in a comprehensible handwriting, the sequence of steps followed to address the problems and the questions.

The grade of each part will span the range from 0/30 to 30/30. The second part (theoretical questions) will be graded only upon obtaining an evaluation of at least 16/30 in the first part (numerical problems). The final grade is determined as the average of the grades obtainted in the two parts.

Solutions where either part one (numerical problems) or part two (theoretical questions) is completely missing, will not be graded.

Should a student get a final grade of 8/30 or lower, he/she will not be admitted to the subsequent exam session. 

In addition to the official exam sessions set by the School of Industrial and Information Engineering, two additional exam sessions will be offered in April and in November.

Students that took the exam of Sistemi Energetici LM in Academic Years antecedent to 2014-15 are allowed to write the solutions in Italian.
