  • Publication number: 20020124874
    Abstract: The inside out gas turbine cleaning method is a new method to clean axial gas turbine compressors. This is done by inserting a specially and fabricated flexible hose with nozzles on it into the first several stages of an off line gas turbine compressor. High pressure hot water with detergent is supplied to the hose and as it is withdrawn from the compressor it blasts dirt from the airfoil surfaces in the compressor. Conventional cleaning sprays water in one direction down the throat of the gas turbine compressor, whereas the this method cleans form the back forward giving a different blast angle with higher pressure water (see FIG. 1). Using both the conventional cleaning method and this new process, the compressor can be cleaned better allowing for improved gas turbine power and fuel efficiency.
