This work presents a descriptive research on how the efficiency of a gas turbine is influenced
by the temperature of the inlet air. The research will analyze the operation of a turbine and show
the effects of the incoming air on the machine's drop in performance. The generating engine
object of this research is the GE LM6000PC aeroderivative gas turbine, located in an electric
power generation park located in Manaus-Am. Based on bibliographic research, information
collected in the generator park, the work developed as a descriptive research, and soon
afterwards, simulations were performed using the Engineering Equation Solver (EES)
thermodynamic function calculations program. The data generated in the EES were inserted in
a spreadsheet and a graph of temperature vs. yield was generated in MS Excel. The graph shows,
by means of variations in the parameters for decreasing the inlet air temperature, the
quantification of the increase, up to 7.00%, in the efficiency of the gas turbine.
Keywords: Temperature. Gas turbine. Efficiency.
