Method and a washing system for washing turbines

摘要

A turbine washing system having a water making apparatus at a turbine site having a turbine. The water making apparatus extracts water from air. A water delivery system delivers the extracted water from the water making apparatus to the turbine to clean the blades of the turbine while the turbine is on-line. A water feeder is provided for feeding the extracted water from the water making apparatus to the water delivery system.;A method for cleaning turbines on-line comprises extracting water from air directly at a turbine site having a turbine and treating the air and the extracted water to obtain extremely clean water having a conductivity of less than 3. This extremely clean water is then fed to the turbine to clean the turbine blades while the turbine is on-line. Preferably the extremely clean water is fed through a deionizer before being fed to the turbine.

主权项

1. A turbine washing system having:
a turbine site having at least one turbine; a first component comprising: a water making apparatus at the turbine site near the turbine, the water making apparatus extracting water from air; the water making apparatus having: filtering and purifying means for filtering and purifying the extracted water to provide extremely clean water having a conductivity of less than 3 microsiemen/cm; and a holding tank in which the extremely clean water is stored over time until needed, the holding tank being at least large enough to wash turbine blades once; deionizing means selectively receiving the extremely clean water from the holding tank as needed and delivering ultra clean water having a conductivity of less than 1 microsiemen/cm; and a second component comprising a water delivery system directly connected to the deionizing means, the water delivery system receiving the ultra clean water and directing it as a liquid to the turbine during delivery and directly onto the turbine blades for a short period of time to wash the turbine blades while the turbine is on-line.
