Abstract: An extended water level range steam/water conical cyclone separator for separating steam from water in a steam/water mixture supplied to a steam drum of a boiler, has a housing comprising a conical portion with upper and lower cylindrical portions, and a conical vane plate. An open bottom extension sleeve portion for discharging water from the steam/water conical cyclone separator housing and connected to the lower cylindrical water outlet portion is provided such that the conical vane plate is located at an intermediate location between the upper conical portion and the open bottom extension sleeve portion of the lower cylindrical portion. Extended water level range capability is thus provided while maintaining adequate steam/water cyclone separator performance characteristics.
