ABSTRACT:
The present invention relates to apparatus and a method for using that apparatus for replacing an existing governor valve on a steam chest of a high pressure turbine that enables chemical foam to be input from outside the turbine for cleaning chemical deposits from the turbine. This device enables chemical foam to be input without penetrating the turbine's main steam loop. When the cleaning process has been finished, the original governor valve can be easily replaced in a short period of time. The apparatus includes an inlet for the chemical foam, a structure for attaching the apparatus to the steam chest of the turbine, and a structure which allows the foam to flow from the stream chest to the turbine.
