CONDENSATE COLLECTION TRAY SYSTEM FOR IMPROVING DEAERATION IN A STEAM CONDENSER,

摘要

A condensate collection tray system for improving deaeration in a steam condenser consists of a plurality of trays (8) located in the cooling tube nests (3, 4, 5) of the condenser and are connected in between the supporting plates and tube sheet and welded to a plurality of supporting plates (11) for collecting the condensate falling down from the upper cooling tube bundle preventing it from falling down on to the lower cooling tube bundles. The trays are inclined towards the steam spaces (6, 7) between the condenser wall and tube nest or between two tube nests for directing the condensate collected on the trays (8) to fall into the steam spaces (6, 7) so that reheating of condensate droplets with steam is faster and more effective and extended into the steam space for restricting the condensate droplets to fall on the lower tube bundles.[IN-KOL-2009-00959A]
