Syllabus
Prerequisites: No prerequisites.
Knowledge of:
- thermodynamics: first and second law of thermodynamics, main heat exchange mechanisms, heat exchanger sizing, general energy balance and exergetic equations, energy and exergetic analysis of energy conversion processes; reference cycles for steam and gas systems (Rankine and Brayton Joule)
- energy conversion machines and plants: operating principles, characteristic curves and fields of use for turbomachinery, in particular gas and steam turbines.
Target skills and knowledge: Acquire familiarity with the main characteristics of combined cycle gas turbines and CHP plants, mostly from the point of view of performance and their link with users' requests.
Acquire the ability to size the heat recovery steam generator taking into account technological, economic, space constraints.
Learn to consult the relevant legislation, in particular regarding cogeneration plants.
Learn to work in a group, defining the role of each participant of the group itself.
Learn how to present the results of the work clearly and concisely.
Learn to use software for simulation and optimization of micro networks.
Examination methods: Oral
Assessment criteria: The oral examination on the whole program contributes 70% of the final grade for those who carried out the group project, 85% for the others. The presentation of the project is worth 30%, that of the exercise 15%.
By means of open questions, the understanding of the topics covered and the ability to apply the concepts proposed to complex cases are evaluated.
Regarding the presentation of the project or exercise, the ability to clearly and concisely show the results of one's work will be evaluated. Both the oral presentation and the power point (or similar) file will be taken into account. In particular, the candidate will have to make clear what were the starting data of the work, such as the constraints, such as the data he obtained from the literature or the catalogs of the manufacturers, such as his hypotheses, which criteria he used for optimization, which finally, the results obtained.
Course unit contents: - Combined plants (18 h): thermodynamic aspects and performance (8 h); the recovery boiler with one or more pressure levels: design and dimensioning (4 h) regulation (2 h); systems to increase flexibility (2 h); repowering and transformations in a combined system (2 h)
  Mixed gas-steam cycles (2 h)
- Cogeneration (20 h): regulations and general information; (4 h) Cogeneration steam plants (4 h) with description of the operating diagram; Cogeneration gas plants with turbines and with micro-turbines (4 h) and systems with internal combustion engines; ORC; cogeneration (4h)
- Sizing of a cogeneration plant for civil and industrial users (4 h):
- The Homer software (8 h): software description, simulation of cogeneration systems connected to the network, optimization of sizes and configuration, sensitivity analysis.
Planned learning activities and teaching methods: Frontal lessons. Some lessons (8 h) are carried out in a computer lab and involve the use of the Homer code. The course also includes technical visits to plants in the area (for example, an industrial cogeneration plant serving a cooking oven, a gas cogeneration plant for civil users, a combined large-scale and cogeneration plant for industrial users, a cogeneration plant service of a district heating network).
