Technology development in gas turbine compressor washing over the last 10 years and today’s state of the art technology is presented in this paper. Based on various long term field tests and observations, correlation between rate of power degradation and atmospheric conditions can be established. Questions about compressor on line washing with water alone against the use of detergents, as well as washing frequencies are also addressed in this paper. Performance degradation behavior between gas turbines of different sizes and models can be explained with an index of sensitivity to fouling. The implementation of an optimized regime of on line and off line washing in the preventive turbine maintenance program is important. It will improve the plant profitability by reducing the costs of energy production and contribute to a cleaner environment.
