摘要：Abstract The effect of inlet air filtration on the performance of two industrial gas turbines (GT) is presented. Two {GTs} were modeled similar to {GE} LM2500+ and Alstom {GT13} E2-2012, using {TURBOMATCH} and chosen to operate at environmental conditions of Usan offshore oilfield and Maiduguri dessert in Nigeria. The inlet pressure recovered ( P r e c o v ) from the selected filters used in Usan offshore, and Maiduguri ranged between 98.36 ≤ P r e c o v ≤ 99.51 % and 98.67 ≤ P r e c o v ≤ 99.56 % respectively. At reduced inlet P r e c o v by 98.36% (1.66 kPa) and, at a temperature above 15 °C (ISA), a reduction of 16.9%, and 7.3% of power output and efficiency was obtained using {GT13} E2-2012, while a decrease of 14.8% and 4.7% exist for power output and efficiency with {GE} LM2500+. In addition, a reduction in mass flow rate of air and fuel under the same condition was between 4.3 ≤ m a i r ≤ 10 .6 % and 10.4 ≤ m f u e l ≤ 11.5 % for {GT13} E2-2012 and {GE} LM2500+, correspondingly. However, the {GE} LM2500+ was more predisposed to intake pressure drops since it functioned at a higher overall pressure ratio. The results obtained were found worthwhile and could be the basis for filter selection and efficient compressor housing design in the locations concerned.
