CODE 66066 ACADEMIC YEAR 2020/2021 CREDITS 6 cfu anno 1 INGEGNERIA MECCANICA - ENERGIA E AERONAUTICA 9270 (LM-33) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/09 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER 1° Semester MODULES Questo insegnamento è un modulo di: GASDYNAMICS AND POWER PLANTS TEACHING MATERIALS AULAWEB AIMS AND CONTENT LEARNING OUTCOMES The main goal of this course is the presentation of the gas turbine technology and related cycles. In particular attention will be posed on advanced gas turbine cycles, combined cycles, mixed cycles with particular emphasis on design and off-design operations. Some thermoeconomic aspects will be investigated taking into account the economic scenario of the energy market. For gas turbines detailed investigation of blade cooling design and influence on the whole cycle are presented. Also combustors operation and related environmental impacts are presented and discussed, including the emission reduction techniques used in land based gas turbine cycles. Some considerations on low BTU gas utilization are considered in the course. TEACHING METHODS The corse is based on lectures; some practical activities are considered such as the evaluation of GT based cycle performance using in house code (WTEMP); moreover, an experimental activity is planned at the Savona Lab. where a complex MGT test rig is installed. SYLLABUS/CONTENT Simple cycle gas turbine: GT market and system performance; technique to improve the GT cycle performance: inter-cooling, re-heating, regeneration, etc.; Combustion chambers: emissions and control; Blade cooling and TIT limits, blade cooling flow rate calculation;. Combined Cycles: heat recovery steam generator; one, two three pressure levels HRSG with or without re-heating; HRSG once through solution; post-combustion; cogenerative application of combined cycles; combined cycle control using IGV and constant TOT; flexibility operation of combined cycle. Mixed steam-gas cycles: STIG and Cheng cycles; HAT cycle; advanced mixed cycles. Off-design operation of single and two shaft gas turbine based cycles; start up and shut down of gas turbine plants.
