Inlet and exhaust branches on top of turbine (Fig. 4)Steam inlet and exhaust branches located on top of the turbine should have provision for easy removal. This is necessary for inspection of the turbine.Care should also be taken that the whole steam piping system does not drain back into the turbine. The piping must be drained separately since water in the turbine could cause se- vere damage.An additional drain should be fitted to the exhaust line close to the turbine, particularly for condensing turbines, to reduce the flow of water through the exhaust casing as much as possible.
