Interlocks promote safe hydrogen cooled generator purging
Don Horne
KIRK Eagle series valve interlocking products provide process safety control in hydrogen cooled generator purging operations. The company’s Eagle series trapped key valve interlocking systems ensure that users follow a pre-determined sequence of operation for startup and maintenance on generators in power stations, refineries, chemical plants, and other industrial applications. KIRK Eagle series valve interlocks integrate with its echanical and electromechanical trapped key interlock series to form a comprehensive process safety scheme. Purging generator rotating systems with hydrogen reduces drag and windage loss in the system. Improperly introducing air into the generator on startup, without first purging it with carbon dioxide or hydrogen, can create an explosion hazard.
