Stop cooling-water flow in turbine
Whether you stop cooling-water flow through steam condenser when the turbine is slopped?
Expert
You must keep circulate the cooling water for 15 mill or more, so that the condenser has chance to cool down. Ensure to have cooling water flowing through condenser before starting up to prevent the live steam from entering the condenser until it gets cooled. Overheating may cause various leaks and other headaches.
