Abstract
The ability to predict the behaviour of a gas turbine engine and optimize its performance is critical in eco-nomic, thermal and condition monitoring studies. Having identified fouling as one of the major sources of compressor and therefore gas turbine deterioration, a computer-based engine model was developed to optimize the performance of gas turbines. The paper thus presents an analysis of compressor hand cleaning, on and offline compressor washing to actualize the technique using a computer program in Visual Basic programming language with data collected over a period of fifteen weeks for 2 gas turbine plants GT1 and GT2. The results of the data collected, when collated, shows that after washing, the overall operational efficiency changed from 39.2% to 46.25%. To optimize the performance of gas turbine engines, it is therefore recommended that operators should perform a combination of compressor hand cleaning, offline and online washing simultaneously.
Highlights
Gas Turbines (GTs) have wide range of industrial applications
The compressor outlet pressure is an indication of fouling, as this menace causes a reduction of the pressure
It is reasonable to say that online water washing yielded a meaningful result but a combination of compressor hand cleaning during shutdown, online and offline washing resulted to a better performance
Summary
Gas Turbines (GTs) have wide range of industrial applications. Proper maintenance and operating practices can significantly affect the level of performance degradation and time between repairs or overhauls of a GT [1,2,3,4,5]. The correct construction and operation of the components of GT plants are necessary for proper understanding and monitoring. The function of a GT is the result of the fine-tuned cooperation of many different components of the plant. The emphasis of this work is on the turbomachinery or aerodynamic components of the GT. The special contribution of this work to GT operation and maintenance is that it helps to prolong the life of the turbomachinery components of the engine
