Abstract
Thermoelectric Plants have gained increased attention in the last decades at Brazil. The increase in demand for electric power generation and the search for reliability in the energy sector contributed for it. They have more flexibility and possibility of installation near consumption areas, instead of the Hydroelectric Plants which have to be installed near a river or large places because of their reservoirs. For being a non-renewable source of electric generation the thermoelectric plants have to cause less environmental impacts as possible, because of it a study of possible gains in electricity generation and efficiency in a combined cycle through the use of inlet air cooling system for the gas turbine compressor using a evaporative cooling method was performed in this work. The model utilized was validated for Rodrigues and Wander (2016) and was used as base for this study. To change the cooling method was designed an evaporative cooling system applied a TRY(Test Reference Year) for metropolitan region of Porto Alegre, Rio Grande do Sul and Mossoró Rio Grande do Norte, Brazil. The Preliminary results shows the influence of the inlet air cooling for an increase in electric power generation, and is possible to see this influence specifically at summer months which have lower relative humidity than winter ones, that is a great point since the generation is prejudiced mainly at higher temperatures.
