The effect of inlet air filtration on the performance of two industrial gasturbines(GT)is presented. TwoGTsweremodeledsimilartoGELM2500þ and AlstomGT13E2-2012, using TURBOMATC Hand chosen to operateat environmental conditions of Usan offshore oil field and Maiduguri dessert in Nigeria. The inlet pressure recovered(Precov ) from the selected filters used in Usan offshore,and Maiduguri ranged between 98.36 P 99.51% recov ≤ ≤ and 98.67 P 99.56% recov ≤ ≤ respectively.At reduced inlet Precov by 98.36%(1.66kPa)and,atatemperatureabove15 °C (ISA),areductionof16.9%,and7.3%of power output and efficiency was obtained usingGT13E2-2012,whileadecreaseof14.8% and 4.7%exist for power output and efficiency with GELM2500þ. In addition,a reduction in massflow rate o fair and fuel under the same condition was between 4.3 m 10.6 air ≤ ≤ % and 10.4 m 11.≤ fuel ≤ 5% forGT13E2-2012andGELM2500þ, correspondingly.However, the GELM2500þ was more predisposed to intake pressure drops since it functione data high er over all pressure ratio.There sults obtained were found worthwhile and could be the basis for filter selection and efficient compressor housing design in the locations concerned
