Abstract

In this study, the performance of a twin-shaft Industrial Gas Turbine (IGT) at fouling conditions is simulated through a Simulink model based on fundamental thermodynamics. Engine measurements across a twin-shaft IGT system during compressor fouling conditions were considered to validate this study. By implementing correlation coefficients in the compressor model, it is possible to predict the performance of the IGT system during compressor fouling conditions. The change of compressor air flow and the compressor efficiency in the twin-shaft IGT during fouling conditions is estimated. The results show that the reduction of air flow rate is the dominating parameter in the decrease of power generation in an IGT under fouled conditions. The model can provide an insight into the effect of compressor fouling conditions on system IGT performance.
