摘要：

This work performs energetic and exergetic analysis of a CCPP, by using a full-scope simulator, which faithfully reproduces the operation of a real Brazilian CCPP. The analyses are performed for design and off-design conditions. The results present, for the design condition, a generated power of 820.6 MW, a first law efficiency of 51.54% and a second law efficiency of 49.32%. The equipment responsible for the main irreversibilities were the combustion chamber (70.24%), gas turbine (10.75%) and heat recovery steam generator (7.37%). In the off-design scenario, the first and second law efficiencies were decreased by 2.65% and 2.54%, respectively.
