60. The purpose of the separating nozzle in the accumulator of a water-tube, coil-type, steam generator is to separate __________.

The separating nozzle in a steam generator accumulator separates dry steam from the steam and water mixture to ensure only dry steam is delivered to the system, preventing issues like water hammer and erosion in downstream equipment. This function is distinct from condensate separation, superheating, or sludge removal, which are handled by other system components.
