Abstract
In this article, a combined cycle power station (gas-steam) is analyzed, considering air cooling before entering the compressor. Currently what is sought are higher thermal efficiencies, which is why the combined cycle power plants have been chosen, since they make better use of the fuel, producing greater net power, all of which have led to innovative modifications in the combined cycle power plants, improving the performance of this. In this research work, a 243 MW combined cycle plant is taken as the base, whose air temperature when entering the compressor is 32 ° C. Knowing in advance that one of the factors that affects the operation of this plant is the condition of the air when entering the compressor, which when it cools will increase its density and with it its mass flow, obtaining an increase in the power of the gas turbine. In view of this, this work proposes that through the use of a mechanical refrigeration system, air cooling to 15 °C is carried out at the compressor inlet and with this achieve an increase in plant performance.
