Method and system for treating stator cooling water to prevent clogging of strainer in the cooling system of an industrial electrical generator

摘要

A method is disclosed to dissolve cupric oxide (CuO) deposits on a strainer (18) in a stator water cooling system (SWCS) (10) of an industrial electrical power generator. The method injects carbon dioxide (CO2) into the coolant (35, 34) to increase the CuO solubility of the coolant. By increasing the solubility, the CuO level in the coolant is less than saturated. The unsaturated coolant dissolves the CuO deposits on the strainer.
