Resumen
En este estudio se realiza un análisis energético comparativo de una turbina de gas cerrada (TGC) con recuperación de calor, utilizando Helio (He) y Dióxido de Carbono Supercrítico (S-CO2) como fluidos de trabajo. El sistema recupera calor residual de los gases de escape de la turbina de gas simple (TG) 7F.04, que opera a diferentes cargas parciales. Al reducir la carga de potencia de la turbina de gas (TG) del 100% al 70% y al 50%, la potencia de la turbina de gas cerrada que utiliza He y S-CO2 disminuye en 52.6% y 80.53%; y 26.99% y 47.507%, respectiva-mente. Asimismo, la eficiencia térmica del sistema de turbina de gas simple y de turbina de gas cerrada que utiliza He y S-CO2 disminuye 15.855% y 30.69; y 8.64% y 19.095%, respectivamente. Para una carga del 100%, la turbina de gas cerrada que utiliza S- CO2 genera una potencia motor y alcanza una eficiencia térmica del sistema mayor en un 18.31% y 4.7%, respectivamente, en comparación con la turbina de gas que utiliza Helio.
This study performs a comparative energy analysis of a closed gas turbine (CGT) with heat recovery, using Helium (He) and Supercritical Carbon Dioxide (S-CO2) as working fluids. The system recovers residual heat from the exhaust gases of the simple gas turbine (GT) 7F.04, which operates at different partial loads. By reducing the gas turbine (GT) power load from 100% to 70% and to 50%, the power of the closed gas turbine using He and S-CO2 decreases by 52.6% and 80.53%; and 26.99% and 47.507%, respectively. Similarly, the thermal efficiency of the simple gas turbine system and the closed gas turbine using He and S-CO2 decreases by 15.855% and 30.69%; and 8.64% and 19.095%, respectively. For a load of 100%, the closed gas turbine using S-CO2 generates motor power and achieves higher system thermal efficiency by 18.31% and 4.7%, respectively, compared to the gas turbine using Helium.
