Abstract
The present work applies the energy analysis with the objective of determining the overall efficiency of the combined cycle thermoelectric plant installed in Panaíba, in the state of Piauí; as well as to determine the benefits and losses of energy by the different equipment that compose the system, which will be represented by a Sankey diagram of the systems without/with supplementary burning. Correction factors for shaft power, exhaust gas flow, relative humidity, among others, will be used in order to adapt the conditions to the operating location of the thermoelectric plant. It is seen that the energy analysis shows the advantages of the use of natural gas in a combined cycle, which presents a better efficiency of 50,81 % when the thermoelectric plant is without supplementary burning, compared to 47,39 % when the plant thermoelectric is with supplementary burning.
