CODE 60220 ACADEMIC YEAR 2023/2024 CREDITS 6 cfu anno 2 INGEGNERIA MECCANICA 8720 (L-9) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/09 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER 2° Semester TEACHING MATERIALS AULAWEB OVERVIEW The main goal of this course is the explaination of the development of energy systems based on fossil fuels, nuclear fuels and RES. AIMS AND CONTENT LEARNING OUTCOMES The course presents the Energy systems field starting from the already students available thermodynamic knowledge. The main goal of the course is to give the capability to the student to understand and to evaluate in a preliminary way the energy systems performance, including general energy related aspects such as energy resources, environment protection, etc. AIMS AND LEARNING OUTCOMES The students will be capable to understand the different energy systems, their main aspects related to the energy transition PREREQUISITES Thermodynamic, Chemistry TEACHING METHODS Lectures and integrative activities SYLLABUS/CONTENT Worldwide and in Italy energy consumption; the different available energies. Fossile fuels and combustion Machines classification Efficiency: ideal, limit and real; adiabatic and politropic efficiency; global efficiency; impact of the auxiliaries. Steam cycles: efficiency definition; methods to improve the cycle performance: regeneration, superheating, re-heating. Condensation, cogenerative and extraction plants. Steam cycle components (condenser, turbine, pumps, boiler, ejectors, valves, extractions, etc.) Steam cycle control: condenser losses at off design conditions; steam flow rate control, Stodola elipse; Lamination and parzialisation; different boiler-turbine control rules. Gas cycle: ideal simple cycle, limit and real cycle; efficiency and specific work. GT components: compressor, combustion chamber, expander; advanced cycles. Cobined cycles; the heat recovery steam generator; pinch point, subcooling and approach point; the calculation of the optimal evaporation pressure; simple pressure and dual pressure HRSG; cycle efficiency. Internal combustion engine: classification; geometric parameters, cycle 2 and 4 strokes; limit cycle, real cycle. Valves and control; performance curves; emissions and their control or limitation.
