Abstract
An air-cooled steam condensing module with an integral vent condenser has a steam header, one or more rows of condensing tubes between the steam header and a (generally lower) common condensate header. The module also has at least one row of vent condenser or dephlegmator tubes located adjacent the condensing tubes which connect the lower header to a vent header. The dephlegmator tubes may be of the same or larger diameter than the condensing tubes.
Claims15
An air cooled steam condenser module with integral vent condenser comprising:
- (a) at least one row of elongated condensing tubes having a first end region coupled to a steam header for the passage of stem therethrough;
- (b) a common condensate header spaced from said steam header and coupled to a second opposite end region of said condensing tubes, said stem passing through said condensing tubes being partially condensed therein with the remaining uncondensed excess stem portion continuously flowing through said condensing tubes and into said common condensate header, said common condensate header being configured with no baffles or compartments therein which separate or divide the said rows of said condensing tubes;
- (c) at least one row of vent condenser tubes positioned adjacent and generally parallel to said condensing tubes within the condenser module, said vent condenser tubes having a bottom end region coupled to said common condensate header for the passage therethrough of said uncondensed excess steam for the complete condensation thereof, said bottom end region of said vent condenser tubes being slant-cut or tapered thereby forming an angle with respect to the longitudinal axis of said vent condenser tubes;
- (d) a vent header connected to an upper region of said vent condenser tubes;
- and
- (e) means for passing cooling air through the condenser module.

- (d) a vent header connected to an upper region of said vent condenser tubes;
- (e) means for passing cooling air through the condenser module;
- and
- (f) said condensing tubes, condensate header, vent condenser tubes and vent header being dimensioned so that steam entering said vent condenser tubes is at a velocity below the critical counter-current flow limit steam vapor velocity for the vent condenser tubes for reducing stem velocity in the vent condenser tubes and allowing condensation formed in the vent condenser tubes to return to the condensate header;
- and wherein the vent condenser tubes are dimensioned to have a diameter larger than the diameter of said condensing tubes.
