The present invention is directed to methods for cleaning films and particulates from the compressor section and combustion contaminants from the combustion and turbine sections of a combustion turbine. Particulate films and contaminants adhering to the internal components of the compressor section of a turbine are readily removed by pumping a foamed cleaning solution such as a foamed, aqueous surfactant solution through the compressor section. Contaminants resulting from fuel combustion and deposited in the combustion and turbine sections are removed by pumping a second, foamed cleaning solution through those sections. The second solution typically comprises a foamed, aqueous acid solution optionally including a corrosion inhibitor. The compressor section must be isolated from such acid solutions, e.g. by pumping the foamed surfactant solution through the compressor section prior to and simultaneously with pumping the foamed acid solution through the combustion section. A manifold suitable for providing a temporary seal about the air intake of the compressor section and through which a foamed cleaning solution can be pumped is also disclosed.

1. A method for cleaning a combustion turbine having a compressor section, a combustion section and a turbine section, comprising:preparing a stable foam by foaming a first cleaning solution suitable for removing contaminants produced during the combustion process and deposited on the internal surfaces of said combustion and turbine sections without harming said internal surfaces; pumping said foam through said combustion and turbine sections while preventing said foam from entering said compressor section; and removing said foam from said combustion turbine.
