CALVO-GONZALEZ, Alberto E. et al. Ambient temperature influence on gas turbines in coastal subtropical área. Ingeniería Mecánica [online]. 2021, vol.24, n.1, pp. 29-37.  Epub 07-Jun-2021. ISSN 1815-5944.

In this work, the influence of ambient temperature in gas turbines in a coastal subtropical zone was studied, both under design conditions and after years of operation. Statistical methods, direct observation, and expert judgment were used during the study. The fundamental parameters of this machine were statistically processed and compared, depending on the variation of the ambient temperature, plotting their influence before and after maintenance, and with their original behavior. It was found that the high temperature produces a decrease in power of about 2.5 MW. As a possible solution, the cooling of the inlet air was evaluated by different methods, selecting the absorption cooling method, which has a positive impact on the environment, although the size of this equipment is disadvantageous. The economic convenience was verified by the cash flow method, resulting in 6 years of recovery.

Palabras clave : gas turbines; ambient temperature influence; inlet air cooling; economicanalysis; increase of power.
