The Effect of Media System on the Performance and Pollutant ‎Emissions of v94.2 Gas Generators in Ansaldo Unit of Yazd ‎Combined Cycle Power Plant

Due to the increasing importance of energy, optimizing power generation systems and reducing their internal energy consumption are essential issues. Analysis of power generation systems is necessary regarding energy and recognition of their functioning. The present study investigated the effect of media system on the performance and emissions of environmental pollutants in Thermoflow Software by modeling and simulating gas generators of Ansaldo Unit of Yazd Combined Cycle Power Plant. The results showed that Media System reduces the temperature of the inlet air to the compressor by 15 °C. Due to the constant volume of the inlet air, density increases and consequently discharge of the air inlet to the compressor increases by 20 kg/s. This results in an increase of 10 to 15 megawatts per generator and increases the efficiency of the gas cycle by 1%. One of the innovations in this research is the study of the effect of Media System on the emission of environmental pollutants. The results showed that this system decreases NOx and CO2 emissions by 20% per year, which can prevent social costs.
