Steam condenser modules

摘要

An air-cooled steam condensing module with an integral vent condenser (10) has a steam header (12), and one or more rows (14) of condensing tubes (16) between the steam header (12) and a (generally lower) common condensate header (26). The module also has at least one row (28) of vent condenser or dephlegmator tubes located adjacent the condensing tubes (16) which connect the lower header (26) to a vent header (30). The dephlegmator tubes may be of the same or larger diameter than the condensing tubes (16).
