Introduction: The inlet air to compressor may contain
dirt, dust, hydrocarbon fumes etc,. A large portion of these things can be
removed by inlet air filtration. The dry contaminates that pass
through filters as well as Wet contaminants such as hydrocarbons cannot be removed effectively so compressor must be washed with water-detergent solution
online washing. off line washing. Compressor washing frequency The frequency of compressor
washing depends up on the severity and type of atmospheric contamination
The recommended method for establishing the frequency is to monitor gas turbine performance
• Restoration of lost performance• Reduced turbine operating costs• Reduction of gas turbine fuel
13. Start GT and operate at FSNL for at least 5 mts. With 24 hrs wash3. Divert false start drains and exhaust plenum drain to effluent tank.
press the off line water wash off softswitch on the water wash contro display
Place the master operation switch 20TW in auto or remote mode
In the control panel on the skid set water temperature setpoint to cold and the operation selector switch to auto
The gas turbine is now available for commercial service and may be loaded
The inlet air containing dirt, dust, hydrocarbon fumes etc.attached to compressor blades can be removed by compressor washing and increase gas turbine performance.
