Field Evaluation of On-Line Compressor Cleaning in Heavy Duty Industrial Gas Turbines

On-line compressor cleaning of heavy duty gas turbines in industrial cogeneration service has proven to be a cost effective method of reducing the rate of performance loss associated with compressor fouling. By selecting an injection system, and by varying the dosage, frequency, and cleaning products used, an optimum cost effective method can be achieved. This paper evaluates the online compressor cleaning system at two 300 Mw cogeneration plants (8 gas turbines) that have been using this system since 1986.
