Abstract
A moisture separator reheater combination includes specially located perforated baffles which function to reduce components of steam fluid velocity flow which are substantially parallel to the cylindrical axis of the moisture separator vessel. These baffles counteract the effects of transverse vortices which produce local pressure variations and adversely affect the efficiency of the moisture separator elements. The use of the baffles of the present invention improves the uniformity of steam flow through the moisture separator elements.
Claims6
A moisture separator for removing moisture from steam flowing therethrough comprising:
- a horizontal substantially cylindrical, pressure-tight vessel having at least one steam inlet opening at the bottom thereof, and at least one steam outlet opening at the top thereof;
- a pair of banks of inertial moisture separator elements disposed within said vessel;
- structure defining means for directing the flow of steam between said at least one inlet opening and said at least one outlet opening through said inertial moisture separator elements;
- an impingement baffle opposed from said steam inlet within said vessel for promoting a first vortical flow pattern in steam entering said inertial moisture separator, said first flow pattern having a vortical axis substantially parallel to the longitudinal axis of said vessel;
- and
- a plurality of spaced-apart baffle means affixed to the inside of said vessel substantially perpendicular to the longitudinal axis thereof for inhibiting a second vortical flow pattern in steam entering said inertial moisture separator, said second flow pattern having a vortical axis substantially transverse to the longitudinal axis of said vessel.
