Abstract
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 forcing a mist comprising a cleaning solution such as an aqueous surfactant solution through the compressor section. Contaminants resulting from fuel combustion and deposited in the combustion and turbine sections are removed by forcing a mist comprising a second cleaning solution through those sections. The second solution typically comprises an aqueous acid solution optionally including a corrosion inhibitor. The compressor section must be isolated from such acid solutions, e.g. by continuing to force the misted surfactant solution through the compressor section prior to and simultaneously with forcing the misted acid solution through the combustion section. A manifold suitable for providing a partial seal about the air intake of the compressor section and through which a misted cleaning solution can be pumped is also disclosed.
