Performance Study of an Aero-Derivative Gas Turbine System with a Coalescer Filter at Varying Operating Conditions [ READ ]
Fidelis I. Abam, Samuel O. Effiom
The performance of an aero-derivative industrial gas turbine (ADIGT) with a coalescer filter at varying operating conditions is presented. The study determines the aptness of an ADIGT for power generation in two extreme locations. The ADIGT was modeled to operate at conditions of Usan offshore oilfield and Maiduguri desert in Nigeria. For all operating conditions of decrease TET, corresponding decrease in AFR was observed. For ambient temperatures between 15 and 38OC in both environments the AFR, OPR, and IPD declined to above 0.5 %. Equally, for conditions below ISO and 1.8 % drop in TET, a 2.4% loss in AFR and 1.6% gain in OPR were attained. The estimated IPD and AFR values exist at about 90% validity with the experimental. However, for ADIGT to be suitable for power generation in these locations, it will require system modification and the use of inlet air pre-cooling system to bring the ambient air close to ISO.
