ABSTRACT:
A feedwater heater in which a bundle of tubes is disposed in a vessel in the flow path of steam through the vessel. Feedwater is introduced into the tubes for passing in a heat exchange relation with the steam to condense at least a portion of the steam and to add heat to the feedwater. An impingement plate is disposed immediately below the inlet in the flow path for deflecting the steam in a direction transverse to the direction of flow of the steam, and at least one vane is disposed in the vessel in the path of the deflected steam for distributing steam more uniformly throughout the tube bundle.
