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.  

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.
